This wiki has been updated 5 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

February 21, 2019:

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.
