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 (gamers, we’re looking at you), the CPU might fail.

If you encounter a CPU fan speed error on Windows 10, check out this guide to solve it like an expert.

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 it’s 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 can I control my CPU fan speed in Windows 10?

  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 matters into your own hands, there’s nothing as suitable as SpeedFan.

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

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

  1. Download SpeedFan for free
  2. You should see the CPU and GPU fans in the left panel
  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 an extended period of time.

This means that you’ll be safest at around 50 degrees, where the risk of critical damage due to overheating is quite low.

Most users don’t know what to do when their laptop is overheating. Check out this amazing guide and always be a step ahead.

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

Even though SpeedFan is a slick tool, you don’t need to orchestrate the 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 & securityupdate & security windows 10 settings
  3. From the left pane, select Recovery
  4. Under the Advanced Startup, click Restart Nowadvanced 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, you 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 one, 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. 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.
