In this case, you might consider buying a fan controller. While SpeedFan covers a wide range of motherboards, there are still some that are beyond even its impressive reach. Here you can see a list of the motherboard’s fan controllers, with a drop-down list near the middle where you can choose each fan individually. When you’ve installed it, launch it and click on the Fan Control tab. This free app gives you an impressive amount of control over your fans which are connected to the motherboard, allowing you to choose how fast they spin at various temperatures. These are contained in something called the BIOS (Basic Input/Output System), which you can access and change. When you first turn on your PC it will run through various checks and settings before you can use it. So, if it’s stuck between boxes under your desk, buried amidst a pile of papers, or just in a poorly ventilated area, then you’re going to hear the whirring of those fans more often than might be necessary. It’s also a good idea to make sure that air can pass freely around your PC. AĬan of compressed air is another option here. You can use a vacuum cleaner to remove dust, just ensure that the plastic nozzle is fitted to the end and that you’re very careful not to touch any of the components. If you can, open the case of your PC and do a little spring clean. A build-up of the material in or around the fan ports can make it harder for hot air to escape, and thus make the fans worker even harder.
You should immediately see that it needs to be able to read sensor values and send signals to fans sensor chip makers are really secretive about how to address them, and hardware makers do their own shonky stuff, but if your particular sensor/fan configuration has been reverse-engineered enough that it works with lm-sensors then fancontrol will work well.Dust is a major problem with PCs, as they attract it like no one’s business. This is a simple service that reads values from your temperature sensors, looks up your preferences from a text file, then sends a signal to your fans. In the absence of that, or if the hardware fan curves aren't to your liking, you can have software control of your fans with the appropriately-named fancontrol. If your computer came with Windows, and the manufacturer has some application to harvest that sweet, sweet, user data that they want to encourage you to use, then they may have turned off hardware control by default, but if they aren't too user-hostile there will be a way to turn it on in your UEFI setup. The best way to control the fans is to have the hardware do it.
