This might seem obvious, but an air cooling setup relies on cooler air outside the case than inside. Fans on the rear and of the case are usually exhaust fans, expelling the hot air warmed up by the components back into the room. The fans on the front of your PC’s case are typically intake fans, drawing in the relatively cool air of the surrounding room to lower the temperature inside the case. As the components in your computer operate, they build up heat, which can lower performance and eventually damage the hardware if it goes unchecked. The central concept of air cooling is very simple.

The Basics: Cool Air Comes In, Hot Air Goes Out But there are a lot of great fans out there, so dig around sites like Newegg to see what you can find. If you don’t want to do a ton of research, we highly recommend Noctua fans for great noise-to-performance ratio-though some of their models are on the pricier side (not to mention the standard line is butt-ugly). Splurge on LED fans if you want, or save some money and keep your build low-key. These look cool-especially when coupled with a “tricked out” overall build-but don’t add or detract from performance in any meaningful way.

Static pressure fans are designed to pull or push air with extra force, which is ideal for areas with more restricted airflow-like a water cooling radiator or a large CPU cooler with lots of fins. Airflow or static pressure: Case fans generally come with two types of fins: those designed for airflow, and those designed for static pressure. Airflow-optimized fans are quieter and great for unrestricted areas, like the front of your case.

Some fans and cases even come with manual switches for basic fan control. With a compatible motherboard or a fan controller, though, you should be able to adjust your fans’ speed for the perfect balance, so this won’t matter as much. Faster fans move more air, but slower fans are much quieter.

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.
