Stay frosty with our pick of the best air coolers on the market
Best CPU Air coolers
29 Dec 2021
Keep your chip cool and quiet with one of PC Gamer’s recommended air coolers.
By Chris Szewczyk
These days all-in-one liquid coolers seem to get all the attention. I get it, they look awesome and really add some personality to your rig. But let’s say you don’t have the budget for a liquid cooling solution but still need to cool your CPU. Here’s where the best CPU air coolers come in. Even the most expensive air cooler is nowhere near the cost of an AIO liquid cooler, and they offer simplicity and reliability.
Following the bigger is better mantra is a good start towards finding your ideal air cooler, but you need to make sure it fits in your case. Noctua’s NH-D15 is a mighty beast, to say the least. There’s also some leeway on style here. While maybe not as flashy as some liquid coolers, some air coolers do come with RGB lighting to add some pizzazz to your rig.
DEEPCOOL AS500 Plus Review
A fantastic all-round cooler
DEEPCOOL AS500 Plus CPU Air Cooler, Universal RAM Height Compatibility, Two 140mm...
- Single tower CPU cooler 142x98x164mm maximize the heat sink for mighty heat dissipation
- Pure copper botom with five pieces 6mm nickel plated heat pipes maximize thermal conductivity
- AS500 powerful 220W TDP cooling capacity supports even overclocked CPUs in compact PCs
- Single tower CPU cooler 142x98x164mm maximize the heat sink for mighty heat dissipation
- Pure copper botom with five pieces 6mm nickel plated heat pipes maximize thermal conductivity
- AS500 powerful 220W TDP cooling capacity supports even overclocked CPUs in compact PCs
- Dual-fan 140mm PWM 1200RPM offers 70.81CFM each to build a summit air cooling system
- AS500 keeps noise level under 29.2dB(A) even in its full load capacity for quietness needs
- CPU air cooler with 5V-3Pin ARGB motherboard SYNC to build a fabulous world of lights
- Controller in package allows quick lighting adjustment without installing additional software
- Standing 164mm tall, please check your PC case CPU cooler hight limit before buying
- Adapting Intel LGA2066/2011-v3/2011/1700/1200/1151/1150/1155 AMD AM5/AM4
The Deepcool AS500 received worthy attention when it was released, but the AS500 Plus with its additional fan elevates it to the point where it can compete with any single tower cooler on the market. At the same time, it undercuts competitors in price. Even if you spent double the money on a premium single tower cooler, your cooling performance won’t be a lot better.
Its cooling ability belies its compact dimensions. Only more expensive dual tower coolers beat it, but not by a lot. Its dual fan design no doubt helps, though it’s also quiet. Cooling and low noise levels are welcome, then add to that great build quality and subtle ARGB good looks and there’s nothing to complain about. It even comes with its own ARGB controller, and there’s a white version too if you like. The Deepcool AS500 Plus punches above its weight. Short of stressing it with an overclocked high-end processor, the AS500 Plus ticks all the boxes.
BE QUIET! Pure Rock 2 Review
An affordable and effective cooler that’s very quiet
be quiet! Pure Rock 2 Black, BK007, 150W TDP, CPU Cooler, Elegant...

- WARRANTY: Supported by a reliable 3-year manufacturer’s warranty.
- German Design I German Engineering I German Quality I German Performance
If the brand name didn’t already give it away, the Be Quiet Pure Rock 2 really is quiet! It’s a single tower cooler equipped with the company’s highly regarded Pure Wings 2 PWM fan which carries a low 26.8 dB(A) noise rating. That means it’s very quiet indeed. It feels really solid too, an indicator of good build quality, even at its low price. We wouldn’t describe the Pure Rock 2 as the most beautiful cooler on the market. But if you do have a windowed case, you could consider the smarter black version for a more polished look instead. The Pure Rock 2 is primarily designed to cool, unseen and unheard.
Though perhaps its 15OW TDP is a touch optimistic, and at least an Intel Core i5 11600K or AMD Ryzen 7 5800X won’t present a problem for the Pure Rock 2. For anything other than high-end CPUs the Pure Rock 2 will keep your chip cool and quiet. If you’re not interested in bling and want something that’s a step up from bundled coolers, this is great.

- Renowned Noctua quality backed up by 6-year manufacturer’s warranty, deluxe choice for Intel Core & Core Ultra (e.g. 285K, 265K, 245K) and AMD Ryzen (e.g. 9950X, 9900X, 9700X, 9600X)
The Noctua NH-D15 3 Chromax Black is considered by many to be the best air cooler on the market. We really love it too. It performs brilliantly, it’s got excellent fans that are a welcome black color, and its build quality is fantastic. Really only 360mm AIO coolers outperform it. If you want an air cooler that can handle any consumer CPU on the market, you might find one to match the Noctua flagship, but you won’t find any that truly beat it. Under normal operation the NH-D15 can be considered silent, but when pushed hard it becomes louder than you might expect. Though we don’t mind having some optional cooling headroom when needed.
Its expense, and sheer size, are the only things that count against it in my eyes. Notably, though, Noctua has a tradition of support for new sockets, and LGA 1700 support will either be included in the box or available to you as a free kit, depending on when that NH-D15 was made.
NOCTUA NH-P1 Review
Quiet computing enthusiasts, look here

- Recommended for CPUs with low to moderate heat dissipation (see CPU compatibility list), e.g. Intel 285K, 265K, 245K or AMD Ryzen 7900, 7700, 7600, etc.
Noctua’s NH-P1 passive cooler is very much a niche product, and one that fans of quiet computing have been looking forward to for some time. It’s expensive, bulky, and generally limited to CPUs in the 65W range. Sounds like a dud? Hell no. Its appeal may be limited, but if you’re a user who values silence above anything else, then the NH-P1 will be exactly what you’re looking for. The NH-P1 is a great match for something like an AMD 5700G. That way you could omit a discrete GPU and play esport titles in silence. The NH-P1 will keep this class of CPU boosting to its max, but only if you have at least some airflow. The chances are you have a rear case fan that’s not far away from it anyway. If you want, you can still opt to attach a fan, too.
The NH-P1 is built for a specific purpose. If you sleep near your PC or run a lounge room media center, the NH-P1 will go a long way to ensuring that your PC is truly silent. Clearly it’s not meant for everyone though.
When it comes to AMD Ryzen desktop CPU support, things get a little easier. Aside from the aforementioned Threadripper chips, all other Ryzen CPUs use the same AM4 socket. That means that any CPU cooler that lists AM4 support is good right the way up to the current Ryzen 5000-series CPUs.
CRYORIG C7 Review
A great choice for a truly tiny system
CRYORIG C7 Cu - 47mm Tall, SFF Mini ITX Full Copper CPU...
- CPU-Cooler
- Air Cooling
- CPU-Cooler
- Air Cooling
The Cryorig C7 has 5 been on the market for sometime, but it’s been updated to support newer sockets. It’s perfect for a truly compact small form factor system thanks to its 47mm height and adherence to ‘keep-out’ zones, where it will not interfere in any way with other system components.
The C7 destroys the stock Intel cooler. It’s rated for up to 100W but is better suited to 65W class CPUs. This leaves it a bit of headroom for Turbo bursts. If you’re overclocking, or using a high core-count processor, you can give it a pass, but that’s to be expected. With the right CPU it will stay surprisingly quiet for its compact size. Its top flow design will help to cool the VRM and M.2 SSD, too, something that can be neglected in compact systems.
The Cryorig C7 is a niche cooler, but for the tiniest builds, the C7 does an admirable job. If you want a little bit of extra TDP headroom, there are copper and graphene coated versions, too.
BE QUIET! Dark Rock TF 2 Review
Cooling for your whole system
be quiet! BK031 Dark Rock TF 2, 230W TDP, CPU cooler, Intel-1200/2066/1150/1151/1155...
- Socket compatibility AMD: AM5 / AM4.

- Two heat sinks with anti-vibration rubber inserts
Keeping your CPU cool 6 is vital, but so is overall system cooling. A cooler like the Be Quiet Dark Rock TF 2 blows air downwards, which helps to keep hot running M.2 drives, and your vital motherboard VRM, running cool. This is something that can often be overlooked in AIO cooled systems that lack good airflow over the motherboard, particularly if you have a GPU heating up everything around it. The Dark Rock TF2 performs much like other single tower air coolers, and though it’s on the pricey side, it’s not unreasonably so given the inclusion of two high-quality fans. Its ability to mount a fan above or below the heatsink (or both) adds a lot of installation flexibility. You can use it in all kinds of systems from powerful gaming PCs through to compact SFF systems.
In the Be Quiet tradition, the Dark Rock TF 2 is very quiet, particularly under low loads and with a rating of up to 230W, it can handle all modern CPUs, though overclocking will be beyond it.
