What Size Case Fans Do I Need For My PC?

We stock several sizes of case fans and PC cooling fans here at Ebuyer. However, most computer cases nowadays only support 120mm and 140mm case fans. These strike a good balance between cooling and acoustic performance. So, if you're looking to build a brand-new system, you can safely rule out a lot of the smaller sizes of case fans, like 60mm and 80mm. For the most part, they're for older desktops and rack-mounted servers. A few small form-factor cases still use them, too.

For a small fan to move the same amount of air as a large fan in the same amount of time, it must spin at a faster, louder revolutions-per-minute (RPM). If you've ever heard a gaming laptop running at full tilt, then you'll know just how loud small, high-RPM fans can get. So, the larger the fan, the slower you can run it while still achieving decent cooling performance. Going all-in on 140mm case fans, as opposed to 120mm case fans, is worth it if you want the quietest system possible. This is important if you're, say, a streamer who doesn't want any background noise picked up by their microphone.

How Many Case Fans Do I Need?

As a rule of thumb, the more power-hungry your computer's hardware, the more case fans and PC cooling fans you'll want. Your everyday office desktop PC, one with a power-sipping chip and no dedicated graphics card, doesn't exactly need a slew of case fans to keep adequately cool. On the contrary, it wouldn't be the wisest move to equip a powerful, high-wattage gaming PC with a lone exhaust fan.

Most computer cases include at least one case fan, usually mounted toward the rear to exhaust hot air produced by the processor. Those building a gaming rig will ideally want another two case fans in the front to channel fresh, cool air over the CPU and GPU. Of course, this is just a starting point. You can always add more case fans to meet the demands of your hardware.

That said, you shouldn't focus too much on the number of case fans, but rather how they're positioned in your case for optimal cooling performance. Go overboard and install too many case fans and they'll all work against each other, blowing air in any which direction without properly cooling the hardware itself. In other words, more case fans don't necessarily equate to better cooling.

Instead, what you should strive for is airflow with a strong sense of directionality. As covered on the computer cases page, you want what's known as a 'push-pull' configuration. This is where intake case fans 'pull' air through the case's panels, dust filters, radiators, and so on, and exhaust fans 'push' hot air out of the case, thereby ensuring a constant flow of air is passing in-and-out of the case and its components.

Airflow Fans vs Static Pressure Fans

Broadly speaking, there are two types of case fans: airflow fans and static pressure fans. Corsair offer both 'AF' airflow fans and 'SP' static pressure fans, for example.

An airflow fan's objective is to move the most amount of air in the shortest amount of time. How much air a fan can move, or displace, is measured in cubic-feet-per-minute (CFM). And if you look at the spec-sheet of an airflow fan, its CFM will more than likely be greater than a static pressure fan's. However, an airflow fan won't displace air with much force. When something's blocking its path - an all-in-one water cooler's radiator, for example - it will struggle to force air through it. A static pressure fan, on the other hand, is stronger and better equipped to force air through a point of resistance.

As a result, you want to mount static pressure fans to heatsinks and radiators, and airflow fans to your case's intakes and exhausts. More and more computer cases are being designed with high-airflow mesh panels, offering very little resistance for airflow fans. A bulky drive cage or even a dust filter can be enough to lessen the effectiveness of airflow fans, in which case you'd be better off with static pressure fans.
