Whether you’re aiming for record-breaking overclocks or just to build a PC that doesn’t get loud under load, you should choose the best CPU cooler you can afford. Picking the best cooler for your best CPU is a key decision in any processor upgrade or new PC build. The best CPU cooler will make a substantial difference in temperatures, noise, and even performance -- especially if you're overclocking. 

If your CPU cooler can’t keep up with the heat your processor is generating, that could result in lesser performance or even a shorter lifespan for your processor--and no one wants that.

Don't forget to consider thermal paste or another thermal interface material (TIM), though. Nearly all coolers will come with some kind of paste, either in a syringe or pre-applied to the cold plate. But to make sure you're getting the most efficient thermal transfer between your CPU and cooler plate, check out the many thoroughly tested products in our roundup to find the best thermal paste for your CPU.

Best CPU Coolers For You

If you’re not sure if you want to go the air cooling route (a hefty metal heatsink with fans) or opt for a liquid-cooled AIO (a pump attached to a radiator and fans), there are a few things to consider. Big air coolers tend to take up more internal space in your PC case, or at the very least they need more vertical clearance off your best motherboard, which can limit your case options. Air coolers can also be louder and less efficient than liquid coolers at moving heat away from your CPU and out of the chassis, although these days that’s not always true. If you can go the extreme route, there are fanless air cooling options like Noctua's Colossal NH-P1.

Air coolers usually cost less than AIOs, though that line is blurring as well. AIO coolers are getting increasingly affordable, while high-end air coolers reach toward and sometimes above the $100 range. While it's an extreme case (in price, size and cooling abilities), the Ice Giant Prosiphon Elite has an MSRP of $170, which competes with many large AIO coolers.

If money isn't a major concern and silent operation and low temperatures are important to you, you may want to consider a custom cooling loop. For more on how these can perform (and how good they look), check out our Blue Shift build feature. But know that custom cooling loops are always much more expensive than most other cooling alternatives.

Quick Shopping Tips

When choosing the best CPU cooler for your needs, consider the following:

  • Own a recent Ryzen CPU? You may not need to buy a cooler, but it depends on the model. Most Ryzen 2000 and 3000-series processors and some older Ryzen models ship with coolers, and many of them can handle moderate overclocks. Note, though, that the most-recent Ryzen 5000 CPUs don't ship with coolers in the Ryzen 7/9 range. If you want the best CPU clock speed possible, you’ll still likely want to buy an aftermarket cooler anyway. But for many Ryzen owners who don't plan to push their silicon to the limit, the best CPU cooler might just be the free one in the box.
  • If opting for a large air cooler, be sure to check clearances before buying. Big coolers and low-profile models can bump up against tall RAM and even VRM heatsinks sometimes. And tall coolers can cause clearance issues with your case door or window. Be sure to check the dimensions and advertised clearances of any cooler you're considering and your case before buying.
  • Remember that, all else being equal, more fans equals better cooling, but more noise. The coolers that do the best job of moving warm air away from your CPU and out of your case are also often the loudest. If fan noise is an issue for you, you’ll want a cooler that does a good job of balancing noise and cooling. If you can set your cooler's fan speeds based on temperatures in your motherboard's BIOS, that should also help.

Cooler Master has pulled out all the stops to release an excellent option in the large heatpipe cooler arena. The MasterAir MA624 Stealth trades blows with some of the best CPU coolers we’ve tested. It even comes with a third 120 mm fan to use when tall DIMMS create clearance problems. The MasterAir MA624 Stealth doesn’t glitter with RGB lighting, which many will find refreshing. But it does shine on merit, as an effective near-silent thermal solution for some of the most potent desktop CPUs from both Intel and AMD--as long as you don’t count Threadripper.
