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. Open up Windows’ Task Manager and see if there are any programs working hard that shouldn’t be.

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.
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. And I just want to say thank you as well for your hard work on making this feature possible.A good set of fans can keep your computer from overheating, but they can also make your computer sound like a wind tunnel. And since it's new, I don't want to make it overheat by mistake.
I tried undervolting, disabling TurboBoost, official Dell power manager but none of these solutions kept it quiet. Sorry If I am asking too much questions but I recently purchased this laptop (DELL G3) and the fans get really loud during light usage. And I just want to say thank you as well for your hard work on making this feature possible. For "Custom Auto", which sensor should I use? (screenshot attached) Should I keep it unchecked?ĥ.There is so much temperatures being monitored, which one is the most important one to check if the laptop is overheating? (attached a screenshot for my laptop).Ħ.
I figured most of it but I have a couple of questions, if I may ask.ġ.Does "System Auto" reset the fan controls to the manufacturers default?Ģ.Does shutting down and restarting the computer reset the fan controls to the manufacturers default?Ĥ.Is the "Respin period" for HWInfo to regain control of fans in case the manufacturers default take control? I find that my manual settings are not being overridden for my laptop.
