Big or little: Generally bigger fans can move the same amount of air as smaller fans at lower revolutions per minute.You’ll need to make sure they’re sized right to fit the screw mounts on your case, obviously, but beyond that you’ll also want to consider: That said, cooling fans come with a surprising amount of variation. Deciding on a cooling approach that matches your case and your components before you go shopping for fans and coolers can be helpful. Pick the Best Fans for Your PCĪny desktop PC with standard case fan mounts will work (80mm, 120mm, 140mm, 200mm-it doesn’t mater as long as they’re consistent).

But there are a few basic principles you can apply to almost any build to get optimal airflow, and thus, optimal cooling. We’re talking about physics, thermodynamics, all sorts of fun stuff. It’s often explained as “LEGO for adults.” But managing the air cooling system within a PC is considerably more complex. Building a modern desktop PC is surprisingly easy, thanks to modular parts and a lot of solid engineering.
