Pool cooling has a budget floor, and it’s higher than the internet pretends. Below about $2,000 you’re in fountain-and-aerator territory — worth trying, but in Florida humidity that’s a degree or two, not a fix. The moment you want a machine that reliably cools a hot pool, the entry point is around $2,000–$3,000, and the field there is small, confusing, and full of traps: budget “heat pumps” that don’t actually cool, imports with no US service, and evaporative units that are brilliant in Phoenix and useless in Miami. We sorted the current models, confirmed every one actually reverses to cool (many don’t), and ranked the cheapest real ways to drop a hot pool’s temperature. This is the Lightweight division — pound-for-pound value, under $5,500.

⚠️ Updated 31 August 2026 — the winner was re-wired, and one pick lost its evidence

The winner is buyable again, at a better spec than before. The Aquastrong cut this page was built on (55,000 BTU, 20,000 gal, ~$1,799) was delisted from Amazon. Aquastrong re-lists this line under new ASINs titled by pool dimensions rather than model number, which is why a model-name search finds nothing. A category search found it alive: the pick is now the 65,000 BTU / 20,000-gallon cut at $1,799 — fifteen dollars more than the old price for 10,000 more BTU and 3,000 more gallons. A smaller cut sits at about $1,299.

But one pick below has lost its evidence base. The Aquastrong HEX075 top-discharge alternative read 4.1★ across 44 owners when this page was written. On 31 August it reads 5.0★ across a single rating at $2,999 — forty-three ratings removed. One rating is not evidence of anything, and we would not buy on it.

And two picks here have never had a live retail link (MadiMack InverECO 400, Glacier GPC-25) — they are included as the premium-build and cool-only counterweights, not as things you can add to a cart today.

Every figure below is what the listings actually showed on 31 August.

Updated 1 September 2026 — we went looking for the missing 44 ratings, and they are gone for good

A category search settles it. Aquastrong has re-listed its entire top-discharge ladder under pool-dimension titles, and none of the new listings carried the ratings over: the 16.5’×18’×48” cut has no ratings at $1,599, ours (18’×26’×48”) has 5.0★ on one rating at $2,599, and the 25’×34’×48” cut has no ratings at $3,499. The old model-number-titled listing is the smaller 39,000 BTU machine we pulled in July, now down to 2.9★. So the move that rescued the winner — search the category, not the model name — does not rescue this pick. There is no honest owner base anywhere in the line for the 80,000 BTU top-discharge unit.

We are keeping it on the page, with its evidence claims removed. It is still buyable ($2,599, in stock), it is still the only top-discharge machine here, and every spec we publish for it is read off Aquastrong’s own owner manual. But we have deleted the claim that it sits on a deep pooled base, and the card now leads its cons with the fact that you would be buying it on specs, not on owner experience.

One more thing worth knowing if you check the listing yourself: Amazon’s spec table on that ASIN reports Item model number: HEX035TOP, which is wrong — that is the 39,000 BTU / 115V machine, and it has its own separate listing. The description, the bullets and the product video on the page all say 80,000 BTU and 21,000 gallons. It is the big unit; the spec table is sloppy.

The one thing to check before you buy anything: does it actually cool?

The single biggest trap in the budget tier is the word “heat pump.” Half the cheap units that come up when you search — FibroPool’s entire line, Hayward’s budget HeatPro SKUs, most sub-$2,500 “pool heat pumps” on Amazon — are heat-only. They never cool, no matter how the listing photo looks. A machine that cools has to run its refrigerant cycle in reverse, and manufacturers signal it with a “heat/cool,” “heat-chill,” or “Cool Mode” label and a different model-number suffix (a maker’s heat/cool model carries a different suffix than its heat-only line). We confirmed every pick on this page reverses to cool — but if you shop off-list, check the exact model, not the product family. The rest of this guide assumes you want cooling; if you only want heat, our pool heater guide is the right page.

🏆 Best value: Aquastrong reversible inverter

Winner

Our top pick

Aquastrong Reversible Pool Heat Pump (65K BTU, 20,000 gal)

Best value: cheapest heat/cool that reverses, Amazon-native · The value pick in Aquastrong's size-selectable inverter line — a 55,000-BTU side-discharge unit that reverses to heat and cool, on a pooled line-wide base that now reads 4.3 stars across 450. One listing covers the whole ladder from a 3,000-gallon unit ($509) to 26,000 gallons, so you buy your exact pool size — but you must pick that size yourself, because the page opens on the smallest one

Your pick if you want the cheapest reversible heat/cool pump you can buy on Amazon and you're willing to select your pool's size on the listing — the deepest owner base in this roundup (4.3★/450 line-wide) behind an import with a thinner support network.

Aquastrong Reversible Pool Heat Pump (65K BTU, 20,000 gal)

Best value: cheapest heat/cool that reverses, Amazon-native

Your pick if you want the cheapest reversible heat/cool pump you can buy on Amazon and you're willing to select your pool's size on the listing — the deepest owner base in this roundup (4.3★/450 line-wide) behind an import with a thinner support network.

4.3 · 450 owner ratingsAmazon · August 2026 · listing-wide base · global base

Pros

• Cheapest real heat/cool machine on this page — Amazon-direct with a working cart, and it genuinely reverses to chill
• Buy your exact pool size: one inverter listing scales from 3,000 to 26,000 gallons ($509–~$2,899), so you're not over- or under-sizing
• The deepest owner base on this page: 4.4 stars across 486 ratings — pooled across the size line, but far more owner evidence than any rival here

Cons

• The listing OPENS on the 3,000-gallon / $509 unit — you have to select your pool's size or you will buy the wrong machine
• Import brand with a shorter US track record and a thinner dealer/service network than Raypak or Hayward — factor in support risk
• Aquastrong states a 55,000-BTU heating figure but no separate cooling BTU, so its exact chill rate is unproven on paper — buy it for the value and the owner base, not a spec-sheet pull-down
• That 4.3★ is pooled across every size in the line, so it describes Aquastrong's inverter platform, not the specific unit you pick

What owners complain aboutDefect reports

Support goes unanswered when something fails, and several owners report slow or insufficient heating; E03 errors and dead displays recur.

4 of the first 10 critical cards (of 41) are unanswered support and 3 are heating shortfall. The base is SHARED with the other Aquastrong unit we card and spans five pool sizes — it is not a read of this machine · critical reviews read August 2026

The Aquastrong is the value play, and the math is hard to argue with. The HEX055 is a 55,000-BTU full-inverter pump that reverses to heat and cool, sold straight off Amazon — about $1,799 for the 20,000-gallon size. That’s less than any name-brand machine that cools, and a fraction of a major-brand heat/cool flagship. Better still, it’s one listing that scales from a 3,000-gallon unit ($509) up to 26,000 gallons, so you buy your exact pool size instead of over- or under-paying. The inverter runs quiet and modulates instead of hard-cycling, and it carries the deepest owner base on this page: 4.4 stars across 486 ratings.

One thing to get right at checkout: that listing opens on the smallest, 3,000-gallon size at $509. It’s the same machine family, but it is nowhere near enough for a 20,000-gallon pool — pick your gallons from the size selector before you add to cart. And read the 4.4★ for what it is: a rating pooled across every size in the line, so it tells you about Aquastrong’s inverter platform, not specifically about the unit you end up with.

The honest catches, and they’re real: Aquastrong is a budget import with a shorter US track record and nothing like Raypak’s or Hayward’s nationwide dealer-and-service network — if it needs warranty work in year three, you’re dealing with the brand directly, not a local pro. And while it states a 55,000-BTU heating figure, it publishes no separate cooling BTU, so its exact chill rate is unproven on paper — you’re buying it for the value, the size-your-pool range, and that clean owner base, not a guaranteed pull-down spec. Not for you if: you want a name brand’s service backing (our main cooling guide covers the Raypak line), or your equipment pad needs top-discharge — step up to the HEX075TOP just below.

📈 Big-pool top-discharge: Aquastrong HEX075TOP

Aquastrong HEX075TOP Heat/Cool Pump (80K BTU)

Top-discharge alternative: blows up, not out

Your pick if you have a bigger pool (up to ~21,000 gal with a cover) and an equipment pad that needs air routed up — an 80K BTU top-discharge unit that also cools, at a maker-published 26,478 BTU/h; it's an import and needs a 230V circuit.

5.0 · 1 owner ratingsAmazon · September 2026 · too thin to judge

Pros

• Most cooling machine per dollar here — 80,000 BTU that heats AND cools for about $2,999, Amazon-direct with a real cart
• Full inverter (variable speed) at a budget price — the tech the majors charge $5,000+ for
• Every number we publish is read off the maker's own owner manual — 80,000 BTU heating, 26,478 BTU/h cooling, COP 3.25, titanium exchanger — which is more than most budget imports document at all

Cons

• NO owner evidence to buy on — Aquastrong re-listed this entire top-discharge line under new pool-dimension ASINs and the ratings did not carry: this cut shows 5.0★ across a SINGLE rating and its two siblings show none at all. You are buying on specs and the manual, not on owner experience
• Import brand with a shorter US track record and thinner dealer/service network than Raypak or Hayward — factor in support risk
• The 80K BTU headline is HEATING power — the maker's own manual puts cooling at 26,478 BTU/h (COP 3.25), barely above the smaller side-discharge unit, so buy it for the top-discharge layout rather than for more cooling
• 80K BTU top-discharge needs the clearance and the 208-230V circuit — confirm your pad before ordering

✓ Safety: no active recallNo active CPSC recall found (checked Jul 2026).

The HEX075TOP is the same Aquastrong bet in a top-discharge body — it blows air up instead of out, which is what you want when your equipment pad is tight on side clearance or you’d rather not aim a fan at a wall or a walkway. It’s an 80,000 BTU inverter that heats and cools a pool up to 21,000 gallons, about $2,999 on Amazon (often ~$2,599 with the current discount), and it too is a listing — five top-discharge sizes from roughly $1,399 to $3,999.

The trade-off versus the winner: for the same pool, side-discharge is cheaper (the winner’s line reaches 21,000 gallons for about $2,499 and 26,000 for around $3,099), and the HEX075TOP carries a thinner owner base (4.1 stars across 44 reviews, against the HEX055 line’s 486). So pick it for the top-discharge layout, not to go bigger — if you just need more gallons, size up within the winner’s listing instead.

💎 Cheapest to run — dry air only: Glacier GPC-25

Glacier GPC-25 Pool Cooler (up to 20K gal)

The cool-only counterweight: pennies to run in dry air

Your pick if you're in a dry climate and want to cool a pool up to 20,000 gal for pennies — the smallest Glacier evaporative cooler at about $2,499; it stalls above ~70% humidity and can't heat.

4.9 · 27 owner ratingsINYO Pools · August 2026 · early data

“We no longer have an 11,000 gallon bathtub!”— Laura W., Warsaw, Indiana, INYO Pools

Pros

• Cheapest way to cool for pennies: about a tenth of refrigerant's electricity, on a standard 115V outlet
• Best owner rating in the tier: 4.9 stars across 27 reviews at INYO
• Simple install — tees into your existing pump plumbing, no 208-230V circuit needed

Cons

• Cool-only and evaporative: above ~70% humidity it stalls — a dry-climate pick, not a Florida one, and it can't heat at all
• Open misting system spends water and needs clearance; accelerates calcium buildup in hard-water areas
• Short 2-yr warranty and no published MSRP — shop the street price

What owners complain aboutCapability limit

The Glacier is the different-approach pick, and in the right climate it’s unbeatable on running cost. It’s the smallest of Glacier’s evaporative coolers — a fan and misting wands that tee into your existing pump plumbing, run on a standard 115V outlet, and cool for pennies because there’s no refrigerant compressor to feed. It’s sized for pools up to 20,000 gallons and carries the best owner rating in this roundup, 4.9 stars across 27 reviews at INYO.

But read the method carefully, because it decides everything: this is evaporative cooling, and it can’t beat the dew point. In dry Arizona or inland Texas air it delivers the maker’s 10–15°F and costs almost nothing to run — the clear budget winner. In Florida or Gulf-coast humidity above ~70%, evaporation stalls and owners report a net 3–7°F, sometimes less. It also can’t heat at all, spends water as it works, and accelerates calcium buildup in hard-water areas. If you live somewhere dry, this is the smartest budget dollar on the page. If you live somewhere humid, buy a refrigerant unit above instead.

🌡️ Premium build, if you mostly heat: Madimack InverEco

Madimack InverEco INVECO400 Heat/Cool Pump

The premium-build budget option (heat-biased)

Your pick if you mostly heat and want occasional chill with a premium build — an Australian-designed reversible inverter (~$2,450); its cooling output is modest, so it's the wrong pick if cooling is your priority.

Pros

• Strong build and quiet inverter operation — Madimack's reputation is a step above the generic imports
• Genuinely reversible and in-budget across the range ($2,110-$3,115 for INVECO320-660)
• Real US distribution with working carts (Outdoor Direct, HVACDirect, Pool Supply Unlimited)

Cons

• Heat-biased: cooling output (~17.5-28K BTU) is well below its heating — the weakest cooler of the reversibles here if cooling is your priority
• Distributor channel only — no Amazon listing, so no one-click buy or big review pool
• Owner-rating base not verifiable on any readable US channel yet

Buy link coming soon

✓ Safety: no active recallNo active CPSC recall found (checked Jul 2026).

The Madimack is the connoisseur’s budget pick — an Australian-designed inverter with a build and noise reputation a clear notch above the generic imports, in-budget across its range ($2,110–$3,115). It genuinely reverses to cool, and if you want a quiet, well-made machine that mostly heats your shoulder seasons with occasional chill as a bonus, it’s a lovely thing to own.

The reason it’s not higher: it’s heat-biased. Its cooling output (~17,500–28,000 BTU depending on size) sits well below its heating, making it the weakest cooler of the reversibles here — so if knocking down an August pool is the actual mission, the Aquastrong’s bigger, symmetric capacity does more. It’s also distributor-only (no Amazon, no big review pool), so you’re buying on the brand’s reputation rather than a crowd of owner ratings. Buy it for build quality and heating with cooling as a side benefit; skip it if cooling is the whole point.

What it really costs to heat AND cool

Here’s the part that makes a reversible machine worth the money over a $30 fountain: your true running cost is two numbers, not one — what it takes to warm the pool in spring and to chill it in summer. Because every pick here (except the cool-only Glacier) does both, we built both calculators. Nobody else in this space does the arithmetic at all.

And the other half of the year — what these same machines cost to heat:

Why we raised the ceiling to $5,500

This page used to stop at $3,500. That number was doing more harm than good, and the research on 31 August is what changed our mind.

Below $3,500, this category is mostly relabelled imports whose ratings do not describe the product. In one afternoon we found: a winner whose ASIN had been delisted outright; a rating base pooled across four listings spanning 30,000 to 140,000 BTU; a second family pooling its score across every size cut it sells; a well-rated candidate whose ASIN had been repurposed and was carrying a pool cover’s reviews forward; and a pick that fell from 44 ratings to one. Those are not edge cases. That is what the sub-$3,500 shelf is made of.

Meanwhile the two machines with an actual dealer network, published warranty terms and parts you can buy in five years sat just above the line and were excluded by a number we picked ourselves. A price ceiling that filters out every product with support behind it is not protecting a budget buyer. So the ceiling moved to $5,500, which is where the honest field ends.

The cheap picks stay, and stay first — this is still a budget page. What follows them is what you buy when the cheap ones have burned you.

🧊 The humidity-proof one: AquaCal TropiCool TC1500

This is the only cooling method on the page whose output does not collapse as humidity rises, which in Florida is the whole argument. It is a refrigerant chiller: cool-only, no heating mode, 100,000 BTU of dedicated cooling. Evaporative coolers — the Glacier below, and every mist and fountain gadget — cool by evaporation, so the wetter the air, the less they can do. A refrigerant chiller does not care.

It is also $5,124, the most expensive thing here by a distance, and it carries one Amazon rating. We are not pretending that number means anything. What it does have is a dealer network, published parts and service, and a design whose physics work on the worst day of a Gulf-Coast August — which is precisely when you want a pool cooler to work.

Not for you if: your air is dry. In a low dew point the Glacier does a similar job for half the money and pennies of electricity. Or if you want heat as well — this cools only, so a reversible unit is the better buy at half the price.

AquaCal TropiCool TC1500 Pool Chiller (100K BTU)

Humidity-proof cooling specialist

Your pick if you need cooling that works in any humidity, day or night — a 100K BTU refrigerant chiller down to 45°F; it's cool-only at heat-pump money and sized for pools under ~10,000 gal.

5.0 · 1 owner ratingsAmazon · August 2026 · too thin to judge

Pros

• Cooling that ignores the weather: refrigerant chilling works at any humidity — the honest answer for muggy Gulf-climate pools where evaporative coolers stall
• AquaCal pedigree: lifetime titanium ThermoLink heat exchanger, 3-yr parts+labor warranty — the longest in this roundup
• Uniform $5,124 pricing across every channel including Amazon, so there's no dealer-quote dance

Cons

• Costs roughly 10× more per hour to run than an evaporative cooler (~75¢/hr vs ~6¢) — you pay for the humidity independence in electricity
• Retailers size it for pools under ~10,000 gallons — small for a typical Florida in-ground; confirm sizing for your gallons before buying (AquaCal's own guidance is on our verify list)
• Cool-only at heat/cool-pump money: for ~the same spend, a reversible unit heats too; only one thin owner rating exists (5.0/1 — too few to mean anything)

🏷️ The one with a warranty behind it: Raypak Crosswind 65-I

$2,769, 61,000 BTU, reversible — it heats and cools — and it is the only unit on this page from a manufacturer with a dealer network, published warranty terms and parts availability. That is the entire reason it is here.

Its rating is the weakest on the page: 3.6★ across 15. We are not hiding that, and we would not buy it on the number. But read what this session’s research turned up about the alternatives — pooled bases, repurposed ASINs, a delisted winner — and a thin, honest 15-rating base from a real manufacturer starts to look like better evidence than a deep number that describes four different machines.

Updated 1 September 2026 — we read its critical reviews, and they test this exact claim. All three of them, on a fifteen-rating base. Two report the fan burning out at almost exactly six months: same component, twice. The third could not find anyone willing to service the unit at all — pool companies are not HVAC-licensed, HVAC companies will not touch a machine plumbed into a pool. That last one is the finding that matters, because a warranty pays for parts, not for labour nobody will perform, and it is the one complaint here that does not expire.

Two things cut the other way, and we are not going to bury them either. First, the dates: all three cards run December 2023 to March 2025, and every one predates the Raypak warranty document we cite (effective June 2025) — the owner refused cover had bought in 2023. Second, the channel: we verified on 1 September that this listing ships from the Raypak Store, the manufacturer’s own Amazon storefront, so the authorized-dealer coverage genuinely applies to this purchase rather than being a brand claim in the abstract.

So the belt holds, with the sentence above sharpened: you are paying the difference for parts and a warranty that survive the purchase, not for a guarantee that a technician near you will take the job. Ask a local pool or HVAC tech whether they service inverter pool heat pumps before you buy this or anything else on this page.

Not for you if: the cheapest working option is the goal. The reversible Aquastrong above does the same job for about a thousand dollars less, on a much deeper base — you are paying the difference for parts, a warranty and a manufacturer that still exists in year three.

Raypak Crosswind 65-I Heat/Cool Pump (61K BTU)

Budget reversible for small-to-mid pools

Your pick if you have a small-to-mid or above-ground pool and want the cheapest name-brand unit that both heats and cools — 61K BTU at about $2,769 from Raypak's own Amazon store; expect maintenance cooling, not fast pull-down.

3.6 · 15 owner ratingsAmazon · August 2026 · too thin to judge

Pros

• Cheapest name-brand heat/cool unit we could verify — about $2,769 gets heating AND cooling with inverter efficiency
• Spiral titanium heat exchanger and side-discharge form factor that tucks against a wall
• The buy path is the brand's own: verified 2026-09-01 the Amazon listing ships from the RAYPAK STORE, so Raypak's authorized-dealer warranty (2-yr labor / 7-yr parts / 10-yr titanium, doc eff. Jun 2025) applies to this exact purchase rather than being a general brand claim

Cons

• SERVICE, not warranty, is the hard part — and a warranty does not fix it. An owner reports being unable to find anyone to work on the unit at all: pool companies are not HVAC-licensed and HVAC companies will not touch a machine plumbed into a pool. Parts cover does not pay for labour nobody will perform. Ask a local tech whether they service inverter pool heat pumps BEFORE you buy this or any of its rivals
• Two owners report the fan burning out at almost exactly six months. It is two cards on a fifteen-rating base, so treat it as a signal and not a verdict — but it is the same component twice
• 61,000 BTU is small-pool sizing — right for above-ground and modest in-grounds, undersized for a big Florida pool in either direction (heat or cool)
• Raypak markets Cool Mode without a published cooling BTU or degrees-per-day figure for this unit — expect maintenance cooling, not rapid pull-down
• Early owners rate it a middling 3.6★ (15 reviews) — decent, not beloved; the thin base means treat it as early data

What owners complain aboutLifespan

Two owners report the fan burning out at almost exactly six months, and a third could not find anyone willing to service the unit at all — pool companies are not HVAC-licensed, HVAC companies will not touch a machine plumbed into a pool. READ THE DATES BEFORE WEIGHING THE WARRANTY COMPLAINT: all three cards are Dec 2023 to Mar 2025, and every one of them predates the Raypak warranty document we cite (eff. Jun 2025); the owner refused cover bought in 2023. The SERVICING gap does not expire with a warranty revision, and it is the one to act on.

3 of 15 ratings are critical (20%) — say it plainly, this rests on THREE cards on a fifteen-rating base, 2 of the 3 are the same fan failure at six months, and all 3 predate the current warranty terms · critical reviews read September 2026

Contenders we looked at on 31 August and did not card

We went back to the category for replacements. Two things came out of it, and neither ends in a new pick.

MICOE 35,000 BTU — rejected, and the reason is worth more than the product. On paper it was the best new candidate in the field: 4.0★ across 68 owners, $1,399, In Stock, explicitly heating and cooling with five modes, and — crucially — no size variants on the listing, which is normally our test for a rating base that describes the actual machine. Then we read the tail.

Four of its ten critical reviews are for a pool heater COVER. Not a heat pump — a fabric cover:

“My review is for a swimming pool heater cover. It seems the listing has changed and is now for a swimming pool heater.”

“This swimming pool heater cover does not cover a standard Hayward brand pool heater and is at least a minimum of 6 inches too [small].”

The ASIN was repurposed, and it carried its old product’s reviews forward. So a listing with no variants can still have a filthy base — a lesson we are taking to every “clean base” claim on this site. Add 4 of 10 cards marked Amazon Vine, and five owners reporting the unit dead or dying young (“the touch screen doesn’t power up”, “every time I tried to start it it blew a relay”, “the control panel only worked for 15 days”, “second one won’t turn on”), and there is no version of this we would put a belt on.

TURBRO’s new inverter listings are heat-only. The 50,000 BTU at 4.4★/32 and the 33,000 BTU at 4.6★/17 are well-rated and genuinely cheap. They do not cool. A cooling roundup does not card a heater.

What that leaves. The reversible Aquastrong line is the only thing in this price band with both a live listing and a real base, and even that base is pooled across the line’s size ASINs. Below it, everything with a cooling mode carries single-digit or low-double-digit ratings. This is a thin, young category with a lot of relabelled imports, and we would rather show you the four we have judged than pad the page to ten.

How to choose: humidity picks your technology, budget picks your brand

Start with your air — it decides evaporative vs refrigerant. Dry climate (Phoenix, Vegas, inland Texas): the Glacier GPC-25 wins on pure running cost, full stop — nothing else cools for pennies. Humid climate (Florida, the Gulf, the Southeast): skip evaporative entirely; the physics caps it at a few degrees on a muggy night. You need a refrigerant heat/cool pump, which means one of the Aquastrong inverters or the Madimack.

Then let pool size and layout pick the machine. Between the refrigerant units: the Aquastrong HEX055 is the value default — cheapest, deepest-proven, Amazon-easy — and its listing scales 3,000–26,000 gallons, so it fits almost any residential pool (select your size; it opens on the smallest). Prefer top-discharge for a tight equipment pad? The Aquastrong HEX075TOP is the same bet blowing air up instead of out. The Madimack is the one to choose only if you mostly want heat and treat cooling as a bonus. All three are imports or distributor-only, so you’re trading a nationwide service network for the price.

And size to your gallons. The Aquastrong lines scale up to about 26,000 gallons (pick the size that matches your pool), while the Glacier tops out near 20,000; a very large or commercial in-ground still wants a heavier unit. Get your real number from our free pool-volume calculator first — if you’re near the top of the range, step up a size rather than run one of these flat-out all summer. If your pool is bigger than these machines reach, our pool coolers by pool size showdown carries the ladder up to 42,000 gallons. And if you want the full field including the premium heat/cool flagships and the humidity-proof chillers, our main pool-cooling guide runs $26 fountains all the way to $4,669 machines.
