The 7 Best Computer Heatsinks
This wiki has been updated 19 times since it was first published in February of 2019. If you want to ensure the long life of any computer, whether it's an always-on server, a heavily overclocked gaming rig, or an ultra-compact Raspberry Pi, heat management should be among your chief concerns. Luckily, no matter the component or its purpose, there are products available to mitigate excess thermal energy. One of these heat sinks will be a great first step to protecting your system.

Editor's Notes
January 21, 2021:
Some of the most useful applications of these are inside Raspberry Pis and other similar single-board computers. The Lanpu Kit and EasyCargo ES-V10, for example, come with enough varied sizes to accommodate a wide range of projects. The Cosmos Lost Ocean and Enzotech BCC9 are both good choices for PCs, and can help to keep VRAM, VRM, and other chips from overheating. The Arctic Alpine Passive is a good choice for low-power CPUs, while the NoFan CR-80EH is surprisingly effective for a fanless CPU cooler. The EK Water Blocks EK-M.2 is an even more specialized unit that's built specifically for NVMe SSDs, which is especially useful for anyone running a custom water loop.

Excess heat is the bane of computers, whether they're built to play high-end games, or perform a single function without wasting much space. And while some people are okay with whirring fans or buzzing pumps, there are some situations where those noises aren't acceptable (and people who simply won't accept distraction). For those times and users, there's a huge selection of heat sinks on the market, though it is a bit of journey to wade through them all. If you're trying to replace your CPU fan with a solid-state cooler, well, you're a much braver soul than me, and you should consider the NoFan and the Arctic Alpine. We at EZVid wish you the best of luck at not frying your processor. The GDSTime is extremely versatile, as its approximate 40mm by 40mm size will fit a decent range of use cases. On the other end of the size spectrum, the Enzotechs are super useful, partially because of those extra-long fins. Of course, if you're elbow-deep (knuckle-deep?) in IoT devices like the Raspberry Pi or anything Arduino, we've got you covered. Depending on your needs, the Lanpu, Lost Ocean, and either EasyCargo will almost certainly be able to help you out. As far as actual user PCs go, the Arctic Accelero accommodates mid-range GPUs quite well, and often better-so than the stock heat sink could. Also, don't forget one of the newest, ultra-hot components: if you've installed a blazing-fast NVMe drive, you may want to slap an EK Water Blocks sheath on it, to ensure your data stays safe.
Special Honors
SilverStone HE02 Essentially the same as a high-end CPU cooler but just without the fan, this powerful option is outfitted with six soldered heat pipes and a huge stack of fins to dissipate heat. It's one of the few that can allow some efficient desktop processors to actually run at their full speed without throttling. silverstonetek.com
