Eight coolers from $17.90 to $119.95, and a number that explains the whole category: one cooler on this page holds 45 percent of all the ratings on it. Two of them together hold 77 percent.
- Check the socket before anything else. Only three of our eight explicitly list Intel’s newest socket.
- Air wins on value, and it is not close. The best-value air cooler here costs $85.05 less than the best air cooler.
- Measure the height. Our top pick is 168mm tall and will not close some cases.
- Prices verified August 26, 2026.
Choosing the best CPU cooler is the component decision most likely to go wrong for a reason that has nothing to do with cooling. A cooler can be excellent, well reviewed and well priced, and still be the wrong purchase because it does not fit your socket, does not clear your memory, or does not physically close your case.
The eight below run from $17.90 to $119.95, averaging $57.09, with 29,970 ratings between them. Five are air coolers and three are 240mm liquid units. That split is deliberate and it reflects where the evidence actually is.
One statistic frames everything else on this page. The Noctua NH-D15 alone accounts for 13,513 of those 29,970 ratings, or 45 percent. Add the CoolerMaster ML240L and two products hold 77 percent of the review volume in this entire category. Cooling is a market with two enormous defaults and a long tail of things most people have never tried.

13,513 ratings at 4.8 stars. That is not merely the largest sample on this page, it is the largest sample behind any single product we have covered anywhere on this site. When a component has been bought that many times and still averages 4.8, the remaining uncertainty is close to zero.
It is a dual-tower air cooler with six heatpipes and two 140mm fans, and the chromax.Black version solves the one complaint people had about Noctua for years, which was the beige and brown color scheme. The accessory kit is genuinely comprehensive rather than nominally so.
The number that matters most is 168mm. That is its height, it is stated plainly in the listing, and it is taller than a good number of mid-tower cases will close on. Check it against your case before you order; our PC case guide covers why cooler height is the constraint people discover last.
- 13,513 ratings at 4.8 stars, the largest sample we have seen on any product
- Dual 140mm fans move more air at lower speed, so it is genuinely quiet
- Publishes its height, which most coolers here do not
- Comprehensive mounting kit covering Intel and AMD
- $119.95, more than three times our best-value pick
- 168mm tall, which will not fit every mid-tower
- The listing does not name Intel’s newest socket specifically
- A dual-tower this size can foul tall memory heatsinks

This is the cooler that rewrote the category. Six heatpipes and two 120mm PWM fans in a dual-tower design for $34.90, which is $85.05 less than the Noctua, and 3,239 ratings at 4.7 stars say it is not a fluke.
It also has the better socket list of the two, explicitly naming AM4, AM5 and Intel LGA 1700, 1150, 1151, 1200 and 1851. If you are building on Intel’s newest platform, this cooler tells you it fits and the Noctua listing does not.
For the overwhelming majority of builds, including both of ours, this is the cooler we would actually fit. The Noctua is better. It is not $85.05 better for a processor that is not being pushed to its limit.
- $34.90 for a genuine six-heatpipe dual-tower cooler
- 3,239 ratings at 4.7 stars, the second-largest air sample here
- Explicitly lists LGA1851, which our top pick does not
- Dual 120mm PWM fans included, not sold separately
- Still a large dual tower, so check memory and case clearance
- Thermalright’s fans are good rather than exceptional
- Mounting hardware is fiddlier than Noctua’s

be quiet! builds its entire product line around one property, and this cooler is the mid-range expression of it: six 6mm heatpipes using direct-touch technology and a single 120mm quiet PWM fan, at $54.90 with 4.7 stars from 433 ratings.
A single fan is a deliberate choice rather than a cost saving. Two fans move more air; one good fan makes less noise. If the machine sits on the desk beside you rather than under it, that trade is usually the right one, and it is the same reasoning we applied to the be quiet! unit in our power supply guide.
One caveat to read carefully. The socket list stops at LGA1700 and does not include LGA1851. On AMD it covers AM4 and AM5 without issue.
- Genuinely quiet, which is the whole point of the brand
- Six heatpipes with direct-touch contact
- 4.7 stars from 433 ratings
- Single-fan design is easier to fit around memory
- Socket list stops at LGA1700, so check before buying for newer Intel
- $54.90 buys more raw cooling elsewhere
- 433 ratings is a modest sample next to the Thermalright

The cheapest thing on this page by $12.09, and it holds 4.7 stars across 1,769 ratings, which is more review volume than five of our other seven picks. Four heatpipes, one 120mm PWM fan, and a socket list that includes AM4, AM5 and Intel up to LGA1851.
This is the cooler for a mid-range processor that is not being overclocked, and it comfortably outperforms the stock cooler that came in the box with your chip. On a budget build it is close to free relative to what it replaces.
Do not put it on a high-end processor and expect miracles. Four heatpipes and a single fan is a specification with a ceiling, and past that ceiling you want the Peerless Assassin for seventeen dollars more.
- $17.90, and 1,769 ratings at 4.7 stars behind it
- Lists AM4, AM5 and Intel through LGA1851
- Vastly better than any bundled stock cooler
- Small enough that clearance is rarely a problem
- Four heatpipes and one fan is a real performance ceiling
- Not suitable for a high-end or overclocked processor
- No lighting, if that matters to your build

Five heatpipes, dual 120mm PWM fans and a 220W rating for $29.99. What earns it a place here, though, is a phrase in the listing that nothing else on this page uses: “Full Memory Clearance.”
Large air coolers overhang the memory slots. If you have bought tall RGB memory, that overhang decides whether the sticks go in at all, and it is almost never stated. A manufacturer willing to make the claim explicitly is telling you they designed for it. Cross-check the height of whatever kit you chose in our RAM guide.
- States full memory clearance, which nothing else here does
- Dual 120mm fans and five heatpipes at $29.99
- Rated to 220W, ample for mid-range processors
- 4.6 stars from 491 ratings
- Socket list stops at LGA1700
- 4.6 is the joint-lowest rating among our eight
- Build quality is functional rather than refined

9,603 ratings at 4.6 stars makes this the second most reviewed product on the page and the default 240mm liquid cooler for most of the market. Gen3 dual chamber pump, 240mm radiator, two SickleFlow 120 ARGB fans, AM5 and AM4 on the AMD side, LGA1700 and 1200 on Intel.
At $89.99 it costs more than every air cooler here except the Noctua, and that is the honest comparison to make: this is $55.09 more than the Peerless Assassin and the performance gap does not match the price gap for a typical gaming processor. What you are buying is the radiator at the top of the case rather than a tower over the socket, which frees memory clearance and looks the way many people want a build to look.
- 9,603 ratings, second only to the Noctua on this page
- No tower over the socket, so memory clearance is a non-issue
- Gen3 dual chamber pump with ARGB fans included
- The safest liquid choice if you want liquid
- $55.09 more than the Peerless Assassin for no guaranteed gain
- Socket list stops at LGA1700
- A pump is a moving part that an air cooler does not have
- Needs a case with 240mm radiator mounting

MSI has built closed-loop coolers for years and the Coreliquid line is the quiet workhorse of that range. The A13 240 with A-RGB lands at $69.99, which undercuts the CoolerMaster by $20.00 while carrying the same 4.6 rating.
The listing does the opposite of sparse. It states LGA1851 support out of the box, AM5, AM4 and LGA1700 brackets in the same carton, a split-flow radiator with the pump built into it rather than the block, and a pump rated to 3,800 RPM on ceramic bearings. Our reservation is the sample instead: 159 ratings is the thinnest evidence behind any cooler on this page.
- $20.00 cheaper than the CoolerMaster at the same 4.6 rating
- LGA1851 supported out of the box, which the CoolerMaster is not
- A-RGB lighting included at a sensible price
- AM5, AM4 and LGA1700 brackets all in the box
- 159 ratings, the thinnest sample behind any cooler here
- A pump is a moving part that an air cooler does not have
- Needs a case with 240mm radiator mounting

A 240mm all-in-one liquid cooler for $44.90, which is only $27.00 more than the cheapest air cooler on this page and less than the be quiet! single-tower. It has two PWM ARGB fans on S-FDB bearings, a PWM-controlled pump, and it lists AM4, AM5 and Intel up to LGA1851.
Thermalright doing to liquid cooling what it already did to air cooling is the short version, and 4.7 stars from 469 ratings suggests it is working. If you want the AIO look and the clear memory area without paying $89.99, this is the entry point.
- $44.90 for a 240mm AIO, less than several air coolers
- 4.7 stars, the highest rating of our three liquid picks
- Explicitly lists LGA1851
- PWM-controlled pump rather than a fixed-speed one
- 469 ratings is a modest sample for a product with a pump in it
- Budget AIO components are budget components
- Still needs a case that mounts a 240mm radiator
Where the ratings actually are
Air or liquid: the honest answer
For most gaming builds, buy air. It is cheaper, it has no pump to fail, it needs no radiator mounting, and at the performance level most gaming processors actually run at, a good dual-tower air cooler matches a 240mm liquid unit. Our best-value air cooler is $55.09 cheaper than our most proven liquid one.
Liquid earns its place for three specific reasons, and appearance is a legitimate one of them. The second is memory and slot clearance: a radiator at the top of the case removes the tower that overhangs your RAM. The third is a genuinely high-power processor, where the extra dissipation is real.
The reasons that do not hold up are that liquid is quieter, which depends entirely on the fans and the pump rather than the format, and that liquid is safer, which it is not. An AIO has a moving part and a finite service life. An air cooler is a lump of metal with a fan on it.
Socket compatibility is the thing that actually bites
This is the same failure mode as the AM4 trap in our motherboard guide and the back-connect trap in our case guide: a specification mismatch that no amount of product quality can rescue.
AMD’s AM4 and AM5 use the same cooler mounting, which is a rare piece of good news, so most coolers cover both. Intel is the problem. LGA1700 and the newer LGA1851 need different provision, and four of our eight listings explicitly name LGA1851: the Peerless Assassin 120 SE, the Assassin X120 Refined SE, the Aqua Elite 240 V3 and the MAG Coreliquid A13 240.
The Noctua does not enumerate sockets in its listing at all, and three others stop at LGA1700. That does not always mean incompatible, because manufacturers frequently supply a free mounting kit on request, but it does mean you cannot assume from the listing alone. Check the processor you chose in our CPU guide against the cooler’s own support page before ordering.
Height and memory clearance
Two measurements decide whether a cooler physically fits, and most listings give you neither.
Height determines whether the side panel closes. Our top pick states 168mm, which is genuinely tall, and it is the only one of the eight that publishes the figure. Every case has a maximum cooler height in its specification, and that is the number to match.
Memory clearance determines whether your RAM goes in beside the cooler. Large air coolers overhang the first slot or two, and tall heatsinks on RGB memory are exactly what they collide with. Only the ID-COOLING states full clearance outright. A liquid cooler removes this problem entirely, which is a better argument for an AIO than most of the ones in the marketing.
The same cooler at three prices
While researching this guide we found one product listed three times at three prices. The CORSAIR iCUE Link Titan 240 RX appeared at $62.30, $79.99 and $119.99, a spread of $57.69. Two of the three listings share an identical 4.7 rating and an identical 1,415 review count, which is what happens when Amazon links product variants together. The third carries only 6 ratings.
We have not included it as a pick because we cannot tell you with confidence which listing represents which configuration. We are including the observation because it is a general hazard rather than a Corsair one. When a cooler you want appears more than once, open every listing, compare the review counts, and check what is actually in the box. A shared review count across two prices means Amazon considers them the same product family, not that they contain the same thing.
What we left out and why
The be quiet! Dark Rock 5 was going to be our quiet pick. It returned an empty price and no usable rating when we validated it, twice, so we replaced it with the Pure Rock Pro 3 from the same range. A product we cannot price is a product we cannot recommend.
A Lian Li Galahad 240mm AIO was dropped for the same reason: no price available at validation.
Several color-variant and digital-display versions of the Thermalright coolers were excluded as near-duplicates of picks already on the list. Where a variant is genuinely different rather than cosmetic, we would have kept it.
How we chose these eight
Thirty-three distinct coolers came back across twelve searches, and every one was a genuine cooler rather than an accessory, so nothing was filtered on that basis. Notably, the first six searches returned nothing but air coolers, including two that asked specifically for 240mm and 360mm liquid units. We ran six more searches aimed at liquid cooling to build a fair comparison, which is how the three AIOs here were found.
Each candidate was then validated individually against the retailer page for price, rating, review count and availability on August 7, 2026. That step removed two products that looked fine in search results and had no live price behind them.
The eight that remain span $17.90 to $119.95 and cover the decisions people actually face: air against liquid, quiet against cheap, and clearance against raw capacity. Neither of our build guides currently specifies a cooler, since the $1,000 build uses a processor that includes one and the $2,000 build budgets for the stock solution. For either machine, the Peerless Assassin 120 SE is the upgrade we would make first.
Frequently asked questions
Do I need a CPU cooler if my processor came with one?
Not strictly, but almost every aftermarket cooler is a large improvement. Stock coolers are built to keep a chip within specification at minimum cost, not to keep it quiet or cool under sustained load. Our cheapest pick is $17.90 and comfortably outperforms any bundled cooler.
Is liquid cooling better than air cooling?
For most gaming builds, no. A good dual-tower air cooler matches a 240mm liquid unit at the loads gaming processors actually run at, costs less, and has no pump to fail. Liquid is worth it for appearance, for memory and slot clearance, or for a genuinely high-power processor.
Will any cooler fit my motherboard?
No, and this is the most common mistake. AMD AM4 and AM5 share a mounting system so most coolers cover both, but Intel LGA1700 and the newer LGA1851 need different provision. Only three of our eight listings explicitly name LGA1851, so check the cooler’s own support page against your processor.
How tall a cooler can my case take?
Every case publishes a maximum cooler height, and that is the figure to match. Our top pick is 168mm, which is taller than a number of mid-towers will close on, and it is the only one of our eight that states its height in the listing. Measure before you order.
Will a big air cooler block my RAM?
It can. Large air coolers overhang the first memory slots, and tall heatsinks on RGB memory are what they collide with. The ID-COOLING SE-225-XT is the only pick here that states full memory clearance outright. A liquid cooler removes the problem entirely, which is one of the better arguments for an AIO.
How many heat pipes does a CPU cooler need?
More pipes generally means more heat moved, but the number alone is not a ranking. Four pipes with one fan suits a mid-range chip; six pipes with two fans handles almost anything a gaming build will do. Our $34.90 pick has six pipes and dual fans, which is why it competes with coolers costing three times as much.
Do AIO liquid coolers leak?
Sealed all-in-one units very rarely leak, but they do have a pump, and a pump is a moving part with a finite service life. That is the real difference from air cooling rather than leak risk. If you want a component you never think about again, buy air.
What size AIO radiator should I get?
240mm suits the large majority of gaming builds and is what all three of our liquid picks use. Larger 360mm radiators help with high-power processors but need a case that mounts them, so confirm radiator support in your case specification before choosing.
What is the best CPU cooler for the money?
The Thermalright Peerless Assassin 120 SE at $34.90. It is a six-heatpipe dual-tower cooler with two 120mm PWM fans, it holds 4.7 stars across 3,239 ratings, it lists every current socket including LGA1851, and it costs $85.05 less than the highest-rated cooler on this page.
The bottom line
There is no single best CPU cooler, only the one that fits your socket, your case and your memory. With that said, buy the Thermalright Peerless Assassin 120 SE at $34.90. It is a six-heatpipe dual-tower cooler with 3,239 ratings behind it, it lists every current socket including LGA1851, and it costs $85.05 less than our top pick.
Buy the Noctua NH-D15 if you want the best air cooler made and your case clears 168mm; 13,513 ratings at 4.8 stars is as close to a settled question as this site has found. Buy the be quiet! Pure Rock Pro 3 if noise is the priority. Buy the Thermalright Aqua Elite 240 V3 at $44.90 if you want liquid without paying liquid prices.
And before you order: check the socket, measure the height against your case, and look at your memory. The rest of the build is covered in our processor, case and power supply guides, and if you would rather buy a machine already assembled, our prebuilt guide covers that.
Prices and ratings on this page update automatically and were last refreshed on August 26, 2026. Every other figure was accurate on August 7, 2026 and carries no guarantee beyond that. Component prices move quickly. Check each one before you buy.
Here is the clearest evidence that cooling does not scale with budget. Our $3,000 build fits the same $34.90 Peerless Assassin we would put in the $1,000 machine, and it is 1 percent of that build. An 8-core X3D processor is not a thermal problem, and the best air cooler made would have cost $85.05 more for no useful gain.
