Not all motherboards support this, so you’ll probably have to check your motherboard’s manual or search the web for answers. If your motherboard only has 3-pin connections, though, you can sometimes control the fans by changing the voltage supplied to the fan. Having a 4-pin fan connected to a 4-pin socket is ideal, since 4-pin connections allow your fans to be controlled through pulse-width modulation, or PWM. In addition, your motherboard can either have 3-pin sockets or 4-pin sockets (or both!). Motherboard-connected fans come in two varieties: those with 3-pin cables, and those with 4-pin cables.

If you can connect them to your motherboard, however, you may have options. If they’re connected to the power supply (usually through a Molex connector), there’s no way to control them through software-you’d have to hook them up to a hardware fan controller. The fans in your computer can get power in one of two ways: From the motherboard, or directly from your computer’s power supply.

The Different Ways Fans Connect to Your PC This is especially common (and necessary!) with home-built computers, but can sometimes work on pre-built desktops and laptops as well-though your mileage may vary. Depending on your computer, you may be able to change how hard and how often the fans run to cool down your PC. If your computer is constantly working hard due to a runaway program, its fans are going to run much more often.īut let’s say you’re still not satisfied.

If you’re using a desktop, make sure there’s some space around the case, not pushed up against a wall or in a closed cupboard.

Make sure your computer is well ventilated.

We have entire guides on cleaning out desktops and laptops. If it’s dusty, clean it out (especially the fans) with some compressed air.

Open your computer and check for dust buildup.

RELATED: How to Thoroughly Clean Your Dirty Desktop Computer If your computer is getting hotter than you’d like, or your fans are louder than you’d like, you should do a couple of other things first: If you are using a laptop or other off-the-shelf computer (like a Dell), chances are your computer automatically controls its fans to some extent already. Let’s start with a really simple question: Do you really need to customize your fan control? How you control your fans depends a lot on your computer, your fans, and how everything is put together, so let’s start with some basics. But there’s nothing quite like automatic fan control, where your PC ramps up the fans when things get hot, and turn them down when it’s business as usual. Sure, you could connect a manual fan controller to your PC, with knobs that set fans to different speeds. Here’s how to control your PC’s fans for superior cooling when it’s working hard, and silence when it isn’t. A good set of fans can keep your computer from overheating, but they can also make your computer sound like a wind tunnel.
