The Best Gaming CPU Coolers
Five air coolers for gaming CPUs, from Noctua's NH-D15 to a low-cost Pure Rock Pro 3, compared on heatpipes, fans and warranty.
By The PC Journal editorial team
12 min read5 products evaluated
Gaming CPUs vary widely in heat: a 65W six-core needs far less than a 120W X3D chip. Match the cooler to the chip, then check height and RAM clearance.
We compared heatpipes, fans, height and warranty from each listing; we did not test these coolers.

Best for
- Most gaming builds.
Skip if
- Skip it if price comes first: the Pure Rock Pro 3 cost less when we checked.
Why we like it
At 160mm tall it fits mainstream ATX cases, and its fans spin to 2,150 RPM. It ships with mounting kits for AM4/AM5 and Intel sockets from LGA1150 to LGA1851. Thin ARGB lines frame the fans.
On heat pipe count it ties with the Dark Rock Elite at 7. On fan size it ties with the NH-U12S redux and the Pure Rock Pro 3 at 120mm. It also offers TRCC control software.
Check that your case offers at least 160mm of CPU cooler clearance before ordering. Its price falls between the Pure Rock Pro 3 and the NH-U12S redux, based on our last check.

Best Single-Tower Noctua4 of 5
Noctua NH-U12S redux on Amazon (opens in a new tab)
The NH-U12S redux is a slim single tower with one 120mm fan.
Best for
- Mid-towers with tight clearance.
Skip if
- Pass if a published heat pipe count matters; this one has none.
Why we like it
It sits clear of the RAM slots and suits 65W to mid-range CPUs in narrower cases. It is a lower-cost redux version of the NH-U12S, with an NF-P12 redux fan that is near silent at idle. It matches the Phantom Spirit 120 Digital EVO and the Pure Rock Pro 3 on fan size (120mm).
Check that your case offers at least 158mm of CPU cooler clearance before ordering. It was priced above the Phantom Spirit 120 Digital EVO and below the Dark Rock Elite at the time of writing. There is no published heat pipe count figure, whereas the Phantom Spirit 120 Digital EVO offers 7.

- Slim single tower that does not overhang the RAM slots
- Lowest height of the picks (158mm)
- A single 120mm fan at 158mm tall
Cons
- No published heat pipe count
- Costs more than the Pure Rock Pro 3 at the time of writing
Best Budget Cooler5 of 5
be quiet! Pure Rock Pro 3 Black on Amazon (opens in a new tab)
The Pure Rock Pro 3 is a black single-fan tower rated at 250W.
Best for
- Budget gaming PCs.
Skip if
- Skip it if heat pipe count matters most to you; the Phantom Spirit 120 Digital EVO offers 7.
Why we like it
It is easy to mount and leaves room around the socket. Six black copper heat pipes and a nickel-plated base sit under a Pure Wings 3 PWM fan. It is rated for 250W.
Its compact offset design improves RAM and VRM clearance, and the fan height can be adjusted. On heat pipe count it ties with the NH-D15 at 6. On fan size it ties with the Phantom Spirit 120 Digital EVO and the NH-U12S redux at 120mm.
It was the cheapest of the group when we checked; the Phantom Spirit 120 Digital EVO was the next step up. If heat pipe count is your priority, the Phantom Spirit 120 Digital EVO (7) is the stronger choice.
Key dimensions & specs
- Heat pipes: 6
- Fan size: 120mm
- Fans included: 1
Pros
- 250W TDP rating
- Pure Wings 3 PWM fan
- Six black-coated heat pipes

How We Chose These Gaming CPU Coolers
Each pick was assessed across 4 criteria weighted for real-world use.
- Sockets
- We checked that each maker names current AM5 and Intel LGA1851 support.
- Fit
- We compared listed heights and footprints, since case and RAM clearance decide what fits.
- Cooling hardware
- We noted heat pipes, fan size and fan count from each listing.
- Support
- We recorded warranty length where the maker states it.
What to Look for in a Gaming CPU Cooler
Key buying criteria so you get the right fit the first time.
Size the cooler to the CPU
A 65W chip runs well on a single tower or a good low-profile cooler. Chips rated at 120W to 170W need a dual tower or an AIO to hold their boost clocks without loud fans.
Check the cooler height against your case
Every case offers a maximum CPU cooler height. Tower coolers run from about 150mm to 170mm, and low-profile coolers from under 40mm to about 70mm.
Leave a few millimetres for the side panel.
Watch RAM clearance
Large towers and low-profile coolers can overhang the memory slots. Tall RAM heatsinks may force you to raise a fan or pick a slimmer cooler.
Makers publish RAM clearance figures; check them against your memory's height.
Warranty reflects fan life
Coolers have few failure points besides the fans. Longer warranties, such as Noctua's and Arctic's six years, cover the parts most likely to wear.
Confirm the mounting kit
Check that the cooler lists your socket: AM5 and AM4 share mounting, while Intel LGA1851 and LGA1700 share hole spacing. Older coolers may need a free or paid adapter.
Bigger fans can spin slower
140mm fans move the same air as 120mm fans at lower speed, so larger coolers are often quieter at the same load.
Fan curves in the BIOS matter as much as the cooler.

Frequently Asked Questions
Is an air cooler as good as an AIO?
A large dual-tower cooler matches many 240mm AIOs and has no pump to fail. AIOs help with very hot CPUs and free up space around the socket.
Do I need to buy thermal paste?
Most coolers include paste, and some ship it pre-applied. Buy a tube only if you plan to remount the cooler.
Do AM4 coolers fit AM5?
Yes, AM5 keeps AM4's mounting, so most AM4 coolers fit. Check the maker's compatibility list to be sure.
Which way should the fans face?
Point the airflow from the front of the case towards the rear exhaust fan. Most tower coolers mount this way by default.
What cooler does a 65W CPU need?
A single-tower cooler handles it easily; a good low-profile cooler works in small cases.
Will a tower cooler block my RAM?
Some do. Check the maker's RAM clearance figure against your memory's height, especially with tall heatsinks or RGB modules.
Bottom Line
The Phantom Spirit 120 Digital EVO is the best gaming cooler for most builds, and the NH-D15 suits the hottest chips. The Dark Rock Elite is the premium quiet pick, the NH-U12S redux fits tighter cases, and the Pure Rock Pro 3 is the budget choice.
