# Best AIO CPU Cooler 2026: 10 Ranked, and the Spec Numbers That Disagree Source: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers Published: 2026-09-19 | Updated: 2026-09-19 | Prices checked on Amazon UK on 2026-09-19 Shopping for the best aio cpu cooler means reading a specification table that often contradicts the marketing copy sitting right beside it. Corsair's NAUTILUS 360 RS ARGB quotes a whisper-quiet 20 dBA pump in its bullets but prints 36 dB in the spec field. MSI's MAG CORELIQUID A13 claims 31.1 dBA fans and a 3,800 RPM pump in the copy, while its own spec table says 20 dB and 2,000 RPM. Meanwhile the TZMRIT PF360's '320 watts' is a TDP rating pasted into a power field, since every other 360mm AIO here draws between roughly 2 W and 16 W. Its headline 165.1 CFM airflow is, by its own bullet, the combined figure for three fans — about 55 CFM each. None of this makes these coolers bad. But the loudest number on the page is rarely the one you can compare. We ranked ten of the best aio cpu cooler models on Amazon.co.uk on price, ratings volume, warranty length and whether each listing's own numbers hold together. Where a brand contradicts itself, we print both figures and let you decide. ## The ranking ### 1. ARCTIC Liquid Freezer III Pro 360 A-RGB - Price: £74.99 | Amazon rating: 4.5 from 1,924 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/arctic-liquid-freezer-iii-360 - Buy on Amazon: https://www.amazon.co.uk/dp/B0DLWFCVSD?tag=ranked10-21 The cheapest 360mm here with a 38 mm radiator, a six-year warranty and a 3.96 W quoted draw — plus a VRM fan no rival offers. This sits first because of what the specification field actually says: a quoted 3.96 W draw, 3,000 RPM maximum, 77 CFM and a six-year warranty that is the longest in this group. At £74.99 from 1,924 ratings averaging 4.5, it is also the best aio cpu cooler here for anyone who wants ARGB lighting without paying the Corsair premium. In practice, the 38 mm radiator is the thickest on this list, and the contact frame for Intel LGA1851 and LGA1700 is a real extra rather than a sticker. The integrated VRM fan is PWM-controlled and cools the voltage converters. The fan cables run inside the hose sheathing, which means only one cable reaches the motherboard. That said, 2.02 kg of filled loop plus a 38 mm radiator needs a case with genuine clearance, and the 4-pin pump header rules out daisy-chaining to a single fan header. If you have one CPU fan header and no hub, the non-RGB version ranked second is the same hardware with fewer cables and £7.50 less to pay. Pros: Six-year warranty — the longest of any cooler in this comparison; Quoted 3.96 W draw against 16 W for the white Corsair NAUTILUS; 38 mm radiator, the thickest here, plus an integrated PWM VRM fan; 4.5 from 1,924 ratings, with 80% of reviewers giving five stars; Fan cables run inside the hose sheathing, so one cable reaches the board Cons: 2.02 kg and a 39.9 cm radiator need real case clearance; 4-pin pump header means no daisy-chaining; Compatible Devices field lists Server as well as Desktop, which is a listing quirk; The ARGB version costs £7.50 more than the identical non-RGB cooler ranked second ### 2. ARCTIC Liquid Freezer III Pro 360 (non-RGB) - Price: £67.49 | Amazon rating: 4.3 from 2,380 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/arctic-liquid-freezer-iii-360-g85p - Buy on Amazon: https://www.amazon.co.uk/dp/B0DLWGG85P?tag=ranked10-21 Same 38 mm radiator and six-year warranty as the winner for £7.50 less, with more ratings behind it — 2,380 against 1,924. Second place, and £7.50 cheaper than the model above at £67.49, with more ratings behind it — 2,380 against 1,924. The trade is lighting: this version has none. For anyone who does not need ARGB, it is the best aio cpu cooler per pound in this article. Mechanically it is the same cooler: 38 mm radiator, 3,000 RPM quoted, 77 CFM, six-year warranty and an LGA1851/LGA1700 contact frame — which is why it earns a place among the best cpu liquid cooler picks at this price. The 'Compatible Devices' field lists Gaming Console instead of Server, which is a listing quirk rather than a design difference. However, it carries the lowest star average in the top five at 4.3, and it is still 2.02 kg of filled loop in a 39.9 cm frame. If you want the best liquid cpu cooler for am5 without paying for lighting, this is the value pick here. If you do want the lights, pay the extra £7.50. Pros: £67.49 — the second-cheapest 360mm in this article; Six-year warranty and a 38 mm radiator, matching the £74.99 A-RGB model; 2,380 ratings, the largest sample in this comparison; Quoted 3,000 RPM pump and 77 CFM airflow; Contact frame for Intel LGA1851 and LGA1700 included Cons: 4.3 average is the lowest in the top five, with 7 one-star ratings per 100; No ARGB lighting at all; 2.02 kg and 39.9 cm long — check case clearance before ordering; Compatible Devices field names a games console, which is plainly wrong ### 3. Corsair NAUTILUS 360 RS ARGB (White) - Price: £79.99 | Amazon rating: 4.7 from 812 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/corsair-nautilus-360-rs-argb - Buy on Amazon: https://www.amazon.co.uk/dp/B0DF7G8JFP?tag=ranked10-21 Highest-rated cooler in this article at 4.7 from 812 ratings — and the clearest example of one listing quoting 20 dBA and 36 dB for the same pump. Third, and the highest-rated cooler here at 4.7 from 812 ratings. The catch sits at the top of the page: the bullets promise a pump generating 'a whisper-quiet 20 dBA', while the specification field prints a noise level of 36 dB. Both numbers belong to the same listing, and 16 dB is not a rounding error. What you get is a 360mm radiator with three daisy-chained RS120 ARGB fans that need one 4-pin PWM header and one +5V ARGB header between them. The cold plate is slightly convex, with paste pre-applied. Meanwhile the quoted 16 W draw is the highest in this comparison — roughly four times the 3.96 W of the ARCTIC at number one. Either way, the white version costs exactly the same as the black one at £79.99, so the choice is cosmetic. If you want the best aio cpu cooler here for a white build, this is it. If you object to paying for ARGB you never switch on, buy the non-RGB ARCTIC instead. Pros: 4.7 average from 812 ratings — the highest star rating in this article; 16 W quoted draw, comfortably inside one 4-pin header's budget; Daisy-chain wiring: three fans, one PWM header, one ARGB header, no controller; Convex cold plate with pre-applied thermal paste; Five-year manufacturer warranty Cons: Bullets claim 20 dBA while the spec field says 36 dB — 16 dB apart; 16 W is the heaviest quoted draw here; No airflow figure published anywhere in the listing; Costs £12.50 more than the non-RGB ARCTIC ranked second ### 4. Corsair NAUTILUS 360 RS ARGB (Black) - Price: £79.99 | Amazon rating: 4.6 from 1,181 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/corsair-nautilus-360-rs-argb-4ypq - Buy on Amazon: https://www.amazon.co.uk/dp/B0DF7C4YPQ?tag=ranked10-21 Identical hardware to the white version for the same £79.99, with 1,181 ratings at 4.6 and a wattage field reading '10 Watt-hours'. Fourth by a whisker: same £79.99, same 36 dB spec figure, same convex cold plate, but 1,181 ratings at 4.6 against the white model's 812 at 4.7. It also carries the oddest single field in this comparison — a wattage listed as '10 Watt-hours', which is a unit of energy, not power. In practice the ARGB model here cools like the £99.98 LCD version below it, because the pump, cold plate and radiator are shared. The daisy-chain wiring is the real feature: three fans, one PWM header, one ARGB header, no separate controller box. For a tight aio cooler for intel lga 1700 build, that saves a genuine amount of cable work. That said, the 4.6 average includes four one-star ratings per 100, and the 36 dB spec figure is the number to plan around rather than the 20 dBA bullet. If your case sits on a desk beside you, this is not the best 360mm aio cooler for a quiet desk build — buy on the spec field, not the bullet. Pros: 4.6 from 1,181 ratings, the third-largest sample here; Same 36 dB spec figure and convex cold plate as the white model; Daisy-chained fans need a single 4-pin PWM and one +5V ARGB header; Five-year manufacturer warranty; Ranks 6th in Amazon's Fans & Cooling category Cons: Wattage field reads '10 Watt-hours' — a unit of energy, not power; Bullets still claim 20 dBA against a 36 dB spec figure; No airflow or radiator thickness given anywhere in the listing; Four one-star ratings per 100 across 1,181 reviews ### 5. Corsair NAUTILUS 360 RS LCD - Price: £99.98 | Amazon rating: 4.6 from 740 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/corsair-nautilus-360-rs-lcd - Buy on Amazon: https://www.amazon.co.uk/dp/B0FGDJ3QP1?tag=ranked10-21 The only Corsair here whose spec table matches its marketing — and £20 buys a 2.1-inch IPS screen on the pump cap. Fifth, and £20 above the non-LCD versions at £99.98. For that you get a 2.1-inch IPS screen on the pump cap. Crucially, this is the one NAUTILUS listing whose spec table agrees with its copy: the noise level reads 20 dB, not 36 dB. Worth noting, the power connector is listed as 3-pin while both cheaper Corsair units are 4-pin, and the quoted draw is 5 W — roughly a third of the white NAUTILUS. At 1.59 kg it is also the lightest of the three Corsair coolers here. The RS120 fans are the same ones used on the £79.99 models, so the cooling hardware is unchanged. By contrast, 740 ratings at 4.6 is a smaller sample than the black non-LCD version's 1,181. If you want the best aio cpu cooler for a case you actually look at, the screen earns its £20. If the case lives under a desk, it does not. Pros: Spec table and marketing copy agree: 20 dB in both; 2.1-inch IPS LCD on the pump cap; 5 W quoted draw, roughly a third of the 16 W white NAUTILUS; 1.59 kg — the lightest Corsair cooler in this article; Five-year warranty, same as the cheaper NAUTILUS models Cons: Power connector listed as 3-pin, unlike the 4-pin pumps on the other Corsairs; 740 ratings against 1,181 for the black non-LCD version; No airflow or fan speed figure published in the spec table; £20 more than the same cooler without the screen ### 6. NZXT Kraken Core 360 RGB - Price: £69.98 | Amazon rating: 4.7 from 198 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/nzxt-kraken-core-360-rgb - Buy on Amazon: https://www.amazon.co.uk/dp/B0FLTZ2SHM?tag=ranked10-21 Joint highest rating here at 4.7, but from 198 ratings — the second-smallest sample — for £69.98 with a confirmed 3,100 RPM pump. Sixth, and the joint highest rating here at 4.7 — but from only 198 ratings, the second-smallest sample in the group. Its best sellers rank of 154th in Fans & Cooling sits far behind the ARCTIC and Corsair entries, which are all inside that category's top ten. The single-frame fan design is the practical feature: three fans in one housing means fewer screws and one cable run. NZXT quotes a 3,100 RPM pump, and the spec table confirms 3,100 RPM, 31.9 dB and 75.05 CFM — an unusually clean case of a bullet and a spec field saying the same thing. At £69.98 it undercuts every Corsair on this page, which makes it the best aio cooler for gaming pc builds on a fixed budget. Even so, 198 ratings is a thin evidence base next to 2,380, and the 12.12 W quoted draw is three times the ARCTIC's 3.96 W. The five-year warranty matches Corsair but trails the six years ARCTIC offers. If you want a long track record before you commit, look at the top of this list. Pros: 4.7 average, joint highest in this article; £69.98 — cheaper than every Corsair here; 3,100 RPM pump confirmed in both the bullet and the spec field; Single-frame fan unit reduces screws and cable runs; Five-year manufacturer warranty Cons: Only 198 ratings — the second-smallest sample in this article; 154th in Amazon's Fans & Cooling category, against 5th for the Corsair LCD; 12.12 W quoted draw, three times the ARCTIC's 3.96 W; No socket list printed in the specification fields ### 7. MSI MAG CORELIQUID A13 360 - Price: £59.99 | Amazon rating: 4.6 from 394 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/msi-mag-coreliquid-a13-360 - Buy on Amazon: https://www.amazon.co.uk/dp/B0BSLK8VYH?tag=ranked10-21 The cheapest 360mm here at £59.99, with a listing whose bullets claim 3,800 RPM and 31.1 dBA while its own spec table says 2,000 RPM and 20 dB. Seventh, and the cheapest 360mm AIO in this article at £59.99. It is also the clearest case of a listing arguing with itself: one bullet claims a pump running 'up to 3800 RPM' and fans at 31.1 dBA, while the spec table underneath says 2,000 RPM and a 20 dB noise level. In practice the fan figures are the ones worth trusting, because they repeat: 500–2000 RPM, 2.361 mmH2O static pressure and 62.6 CFM, with the spec field confirming 62.6 CFM. The radiator uses a split-flow design and the fans arrive pre-installed. If you want the best aio cpu cooler under £60, this is the only 360mm at that price here. The catch is the warranty: three years, against five from Corsair and NZXT and six from ARCTIC. The 'Unit Count' field also reads 130.0 gram, which is not the weight of a 1.65 kg cooler. Skip it if you want a long warranty, or a listing whose numbers agree with each other. Pros: £59.99 — the lowest price of any 360mm in this article; 62.6 CFM airflow appears in both the bullet and the spec field; Enlarged copper cold plate with a split-flow radiator; Fans arrive pre-installed, which shortens the build; 4.6 average from 394 ratings Cons: Bullet claims a 3,800 RPM pump; the spec field says 2,000 RPM; Bullet claims 31.1 dBA fans; the spec table says 20 dB; Three-year warranty, short of the five and six years offered elsewhere; Unit Count field reads 130.0 gram for a 1.65 kg product ### 8. Thermalright FW360 SE ARGB V2 - Price: £69.90 | Amazon rating: 4.6 from 313 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/thermalright-fw360-se-argb-v2 - Buy on Amazon: https://www.amazon.co.uk/dp/B0F66J3QPC?tag=ranked10-21 The cheapest route to a 360mm AIO with a screen at £69.90 — and a listing that states its own weight as 200 g. Eighth. At £69.90 it is the cheapest route to a 360mm AIO with an LCD — a 2-inch screen against the 2.1-inch panel on the £99.98 Corsair. The spec table quotes 28.2 dB, 68.9 CFM and a 3 W draw, all of which sit inside the range set by the bigger brands here. The three TL-M12Q fans daisy-chain and run to 2,000 RPM, which keeps cable clutter down. It is a practical 360mm aio cpu cooler for AM4, AM5, LGA1851 and LGA1700 boards, and the LCD accepts system data, images and animated GIFs. At 28.2 dB it is also the second-quietest figure quoted in this article, after the 20 dB of the Corsair LCD. However, the item weight is listed as 200 g. A 360mm aluminium radiator with three fans and a screen does not weigh 200 g — the TZMRIT cooler below weighs 2.25 kg. That field is wrong, and it is the kind of error that makes every other number on the page harder to trust. If weight matters for shipping or mounting, confirm it before you buy. Pros: £69.90 — the cheapest 360mm AIO here with an LCD screen; 28.2 dB quoted noise, second-lowest in this article; Three daisy-chained TL-M12Q fans running to 2,000 RPM; 2-inch LCD accepts system data, images and animated GIFs; 3 W quoted draw, among the lowest here Cons: Item weight listed as 200 g, which cannot be right for a 360mm cooler; 68.9 CFM quoted airflow is below the NZXT Core's 75.05 CFM; No warranty period given anywhere in the specification fields; 313 ratings, a smaller sample than the Corsair or ARCTIC entries ### 9. NZXT Kraken Plus 360 - Price: £129.98 | Amazon rating: 4.4 from 388 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/nzxt-kraken-plus-360 - Buy on Amazon: https://www.amazon.co.uk/dp/B0F5SZK3WX?tag=ranked10-21 The most expensive cooler here at £129.98, with a 1.54-inch LCD, Zero RPM mode and the shortest warranty in this comparison. Ninth, and the most expensive cooler here at £129.98 — nearly double the £67.49 ARCTIC. For the money you get a 1.54-inch square LCD, a 30 dB noise figure and a 2.16 W quoted draw, the lowest in this group. At the same time, Zero RPM mode stops the fans completely under light load, which no other cooler here advertises. The Turbine pump, pre-applied thermal paste and a single breakout cable from the pump cap keep installation tidy, and the tool-free brackets cover AM5 and LGA1851. The catch is the warranty: two years, the shortest in this article by four years against ARCTIC. It also carries the second-highest share of one-star ratings here, at 7 per 100. If you want the best aio cpu cooler for the long haul rather than the nicest screen, spend less and buy six years of cover instead. Pros: 2.16 W quoted draw — the lowest of any cooler in this article; Zero RPM mode stops the fans entirely at low loads; 1.54-inch square LCD with NZXT CAM control; Pre-applied paste and a single breakout cable from the pump cap; Tool-free brackets covering AM5 and LGA1851 Cons: £129.98, nearly double the £67.49 ARCTIC ranked second; Two-year warranty — the shortest in this article; Seven one-star ratings per 100, the second-worst split in this group; No airflow or pump speed figure printed in the spec fields ### 10. TZMRIT PF360 360mm AIO with 5.5" LCD - Price: £99.99 | Amazon rating: 4.1 from 187 ratings - Full review: https://www.ranked10.co.uk/tech/best-aio-cpu-coolers/tzmrit-pf360-aio-360mm - Buy on Amazon: https://www.amazon.co.uk/dp/B0FLJ7G3L2?tag=ranked10-21 Lowest-rated cooler here at 4.1 from 187 ratings, with a 320 W 'wattage' that is a TDP figure and a 165.1 CFM airflow its own bullet splits across three fans. Tenth. At £99.99 with 4.1 from 187 ratings, this is the weakest-rated cooler in the article, and 12 of those 187 reviews — roughly 6% — are one-star. It has the largest screen in the group at 5.5 inches and 480 x 960 resolution, both well beyond the 1.54-inch and 2-inch panels on the coolers above. The listing is also where the numbers stop meaning much. 'Wattage: 320 watts' is a TDP rating dropped into a power field: every other 360mm cooler here quotes between 2.16 W and 16 W. Its headline 165.1 CFM airflow is, by its own bullet, the combined figure for three fans — roughly 55 CFM each. Meanwhile the pump is quoted at 2,700 RPM and the noise at ≤30 dB. None of that makes it a bad cooler, but if you want the best cpu water cooler for the money, £99.99 buys a Corsair with a five-year warranty and a spec sheet you can read. Skip this one if a long warranty, or a verifiable airflow figure, matters more than a large screen. There is no warranty period printed in its specification fields at all. Pros: 5.5-inch LCD at 480 x 960 — the largest screen in this article; Magnetic screen mount with 270° rotation; Pump quoted at 2,700 RPM across AM4, AM5, LGA1851, LGA1700, 1200 and 115X; ARGB lighting synced to a 5V 3-pin motherboard header; £99.99 for a 360mm AIO with a screen this size Cons: Wattage field reads 320 watts — a TDP rating, against 2.16–16 W for every other cooler here; 165.1 CFM is the combined total for three fans, about 55 CFM each; 4.1 average with 12 one-star ratings from 187; No warranty period given in the specification fields ## Verdict For most builds, the £67.49 ARCTIC Liquid Freezer III Pro 360 is the sensible buy: 2,380 ratings, a six-year warranty and a quoted 3.96 W draw. If you want lighting and a higher star average, the £79.99 Corsair NAUTILUS 360 RS ARGB delivers 4.7 from 812 ratings and a documented 36 dB rather than a claimed 20 dBA. And if you need a display on the pump, the £99.98 LCD version is the cheapest Corsair here with one. Either way, decide which number you trust before you pay: the best aio cpu cooler for your build is the one whose spec table matches its own marketing. Read the wattage field first — 320 W and 2.16 W cannot both be pump power, and the best aio cpu cooler listings are the ones that do not ask you to guess.
