The collaboration of software and hardware is what makes your system working as intended.

Let’s take the CPU as an example. An essential part of a PC configuration, small but remarkably sturdy. However, if exposed to abnormal temperatures for an extended period of time (gamers, we’re looking at you), CPU might fail.

Now, there are various ways to avoid that (extra cooling fans is probably the best of those), and today we’ll show you one that’s rather important —  how to increase the speed of the CPU fan.

This is the first line of defense, and, even though your motherboard controls the CPU fan’s speed, sometimes is the best to tend to that on your own. If you’re not accustomed to changing the CPU fan’s speed, make sure to check the steps we provided below.

How to control your CPU fan speed in a few simple steps

  1. Use SpeedFan
  2. Check BIOS for fan speed options

1. SpeedFan – the best third-party solution for fan control

Most of the time, the CPU fan speed is controlled by built-in resources. However, if you want to take the matters into your own hands, there’s nothing as similar as SpeedFan.

There are some conditions you’ll need to fulfill in order to use it and the configuring isn’t exactly a walk in the park, but it once you get the hold of it — SpeedFan will become the indispensable part of your everyday workflow.

The conditions we mentioned are considering motherboard support for fan control. However, that’s in question only if you decide to add extra cooling fans. In regards to CPU and GPU fans, you should be able to control them without any problems. Laptops are an exception, and SpeedFan won’t be of any use with portable computers, except for monitoring.increase cpu fan speed software SpeedFan

Here’s how to regulate the fan speed on your PC with SpeedFan:

  1. Download SpeedFan from the official site for free.
  2. You should see the CPU and GPU fans in the left pane.
  3. There, you can choose the percentage of fan speed (100% is full throttle). On the right side, you should see the current temperatures of CPU cores individually.
  4. Regulate speed as you like manually or you can automatize SpeedFan to increase the RPM (revolutions per minute) once the temperatures surpass the acceptable values.

Your CPU speed should never cross 70 degrees Celsius, and around 60 degrees is an acceptable limit for the extended period of time. Meaning that you’ll be safest with around 50 degrees, where the risk of critical damage due to overheating is quite low.

2. BIOS settings – built-in way to control CPU fan speed

Even though SpeedFan is a slick tool, you don’t need to orchestrate speed of a CPU fan from the Windows interface. That can be done through the BIOS settings, as well. At least, most of the time. Even though different motherboard manufacturers call it differently, there’s always a fan setting hidden within the BIOS.

With some of those, you can regulate the speed, while others need to be disabled in order to make your CPU fan run with maximum effort.

Here’s how to access BIOS in Windows 10 and tweak fan-related settings on your own:

  1. Press Windows + I to open Settings.
  2. Open Update & security.update & security windows 10 settings
  3. From the left pane, select Recovery.
  4. Under the Advanced Startup, click Restart Now.advanced startup windows 10
  5. Click Troubleshoot.
  6. Select Advanced options.
  7. Choose UEFI Firmware settings.
  8. Click Restart.
  9. Your PC should boot in BIOS/UEFI settings.
  10. Once there, should have an easy time finding the fan configuration settings.

As we already stated, some settings allow you to change the RPM while others are made to make fans silent. For the latter, we advise you do disable it if you’re having overheating issues. That way, your CPU cooling fan will always run at full speed and thus make your PC a bit louder but much less prone to overheating.

With that, we can conclude it. There’s so much more to say about cooling systems in PC’s, but we tried to keep it concise and concentrate on the CPU fan. In case you have questions or suggestions regarding the CPU fan control, feel free to toss them at us in the comments section below.
