Summer has come and gone, and the cold weather of winter is basically here. So, now that you’re going to be spending considerably more time indoors, you might want to think about buying one of the best CPU coolers, so that your CPU stays as cool as the weather. And, if you’re the type of PC gamer who is way too obsessed with building and overclocking the best gaming PC, it only makes sense to buy the top CPU cooler you can get your hands on. Even if you’re not super into overclocking, or you’re just dabbling in the arcane art for the first time, it’s definitely worth looking into ideal CPU coolers either way.
The best CPU coolers are available in an extremely wide variety of shapes and sizes, and are available to a wide breadth of different budget levels. If you want to drop a ton of cash, you can pick up an amazing liquid cooling solution and, if you want to save a few bucks, a fan and heatsink can still go a long way. Either way, if you have one of the best processors, you should take a look at all the coolers that we’ve tested and ranked below – along with pricing, specs, and a brief description of each – we’re sure that you won’t be disappointed.
But, enough with the introductions, let’s dive into what you’re all here for – the best CPU coolers in 2017. Regardless of your budget, no matter what kind of cooler you’re looking for, no matter the aesthetics, we’re confident you’ll be satisfied with our choices here. So, whether you’re in the market for an elaborate, complicated beast like NZXT’s Kraken X62, or you want something a little more subdued and inconspicuous like the Noctua NH D15, you’ll find something here. We’re sure of it.

Six-year manufacturer’s warranty
Too big for some PC builds
The Noctua NH-D15 tops our list for one simple, yet compelling reason: it may not be a liquid cooler, but it can perform just as well as – if not better than – some all-in-one coolers. Now, you might not be overly familiar with Noctua’s name, they’re relatively small in the CPU cooler game, but their entire business is centered around designing coolers, so you know that when you buy one of their products, you’re getting a product by people who really know their craft. Not only will you get stellar cooling performance from this thing, but you’ll also get extremely diminished fan noise as well. When you combine all of that with their six-year warranty, you have a recipe for one of the best CPU coolers you can imagine.
Cooler Master Hyper 212 EVO
Type: Fan and heatsink | Compatibility: Intel LGA 775 – 2066; AMD AM2 – AM3+, FM1 – FM3+ | Rotation frequency: Up to 2,000 RPM | Noise volume: 9dBA – 36dBA | Dimensions (W x D x H): 120 x 120 x 25mm | Weight: 1.26 pounds (0.57kg)
Balanced cooling performance
Heat pipes ideal for conduction
AM4 bracket sold separately
For $29 (£30, AU$43), the Cooler Master Hyper 212 Evo is one of the most affordable CPU coolers you can buy. Given, too, that most online stores offer a rebate on this fan and heatsink combo pack, the Hyper 212 EVO is a prodigious value. Although it only features four heatpipes and aluminum fin structure, this legendary CPU cooler has proven itself to be as efficient as liquid-coolers two-to-three times more expensive than it. These air-coolers are designed to make heat dissipation, quite literally, a breeze, whether you’re playing at max settings or watching YouTube videos in a web browser.
Best low-profile CPU cooler
Type: Fan and heatsink | Compatibility: Intel LGA 1156/1155/1151; AMD AM2/AM2+/AM3/FM1/FM2 | Rotation frequency: Up to 2500 RPM | Noise volume: 14.8dbA – 23.6dbA | Dimensions (W x D x H): 206 x 184 x 37mm | Weight: 1.03 pounds (0.47kg)
Six-year manufacturer’s warranty
Only 92mm fan
This CPU cooler is among one of the smallest we’ve ever used for our own Mini ATX builds. It come from an Austrian company as our best CPU cooler that specializes entirely in PC coolers and fans, which means no compromises are made in the way of quality assurance despite its low-profile form-factor.
NZXT Kraken X62
Type: Liquid cooling system | Compatibility: Intel 2011 – 2066; AMD AM2 – AM4, FM1 – FM2+ | Rotation frequency: Up to 1,800 | Noise volume: 21dBA – 38dBA | Dimensions (W x D x H): 315 x 143 x 30mm | Weight: 3.2 pounds (1.45kg)
Dead silent and high performing
RGB lighting is gorgeous
Price range out of bounds for some
Known best for its cases, such as those produced in collaboration with Asus and Razer, you may be surprised to learn that NZXT’s CPU coolers are every bit as impressive as the hardware which encloses them. The Kraken X62 is no exception, being one of the few 280mm all-in-one liquid coolers to feature RGB lighting. Given that the radiator comes pre-attached and the thermal paste pre-applied, the NZXT Kraken x62 is awfully easy to set up too. The packed-in CAM software, which lets you tweak settings on the fly, is merely icing on the cake.
Arctic Liquid Freezer 120
Best budget liquid-cooler
Type: Liquid cooling system | Compatibility: Intel LGA 2011 – 2066; AMD AM2 – AM3+, FM1 – FM2 | Rotation frequency: Up to 1350 RPM | Noise volume: 22.5dBA | Dimensions (W x D x H): 120 x 120 x 25mm | Weight: 2.65 pounds (1.2kg)
For less than 70 big ones in both US dollars and British sterling, the Arctic Liquid Freezer 120 is a deal you can’t pass up if you’re on the prowl for a liquid cooler that won’t break the bank. While it lacks the bells and whistles of pricier, more extravagant liquid coolers, like the NZXT Kraken, the Arctic Liquid cooler is enough to get you by, not to mention it’s still a massive step up from the classic fan and heatsink pairing. So, while you can’t expect RGB lighting or software – or even hardware-based fan control, the 120mm variant of the Arctic Liquid Freezer will keep your system refrigerated at a (mostly) quiet volume.
Corsair Hydro Series H5 SF
Best low-profile CPU liquid-cooler
Type: Liquid cooling system | Compatibility: Intel LGA 115x; AMD FM2 – FM2+ | Rotation frequency: Up to 1,800 RPM | Noise volume: 36dBA – 42dBA | Dimensions (W x D x H): 167 x 57 x 84mm | Weight: 2 pounds (0.91kg)
Guaranteed leak-free tubing
Compact, all-in-one form factor
Blower style cooler
Even if you have a budget that allows for some of the more serious liquid cooling solutions, even some of the sweetest PC cases don’t permit the sheer mass of a bulkier, dual-fan or even a single 120mm radiator. That’s where the Hydro Series H5 SF proves building small doesn doesn’t mean you have to give up on liquid cooling. NZXT Kraken X62
Type: Passively cooled heatsink | Compatibility: Intel LGA 775 – 1156; AMD AM2 – AM3+; FM1 | Noise volume: 0dBA | Dimensions (W x H x D): 180 x 148 x 180mm | Weight: 1.6 pounds (0.73kg)
You won’t hear a peep
Works well with low-power CPUs
95W TDP limitation
Unless you’re already neck deep in the rabbit hole that is silent PC assembly, you’ve probably never heard of NoFan, a South Korean component company that specializes in helping enthusiasts reach that 0dBA silent sweet spot. In doing so, of course, you can count on severely limiting yourself in terms of power, with its CR-95C fanless solution being limited in compatibility to processors whose TDP fall below 95W. Still, the NoFan CR-95C is worth a shot for those sporting low-power rigs that prioritize tranquility over raw horsepower.
