How to Control Fans on PC

Fans on your computer can power in one of two ways: from the motherboard, or directly from your computer’s power supply. Did you ever control fans on PC?

Control Fans on PC

If they are connected to a power supply (usually via a Molex connector), there is no way to control them with software.

You need to connect them to the hardware fan controller.

If you are hearing your PC fans working, and that voice is annoying you, then before controlling their temperature, check a few things.

Heat is not good for electronics like PCs and laptops. The fans that keep your PC working in good condition, make sure that all the hot air is pushed out of the casing while providing a good breeze for the PC’s internal elements.

The motherboard controls this whole process, and it even detects when the components become hot.

Manufacturers might become enthusiastic with fan settings so that their electronic device doesn’t get hot after a few hours, which is why there are ways for users to adjust them.

Clean the Dust

Open your computer, if possible, and look if there is dust inside it. If it is dusty, then clean it, particularly the fans using compressed air. Secondly, you need to make sure that the PC you are using, is well ventilated.

If you are using a desktop, then make some space around it, and don’t push it directly against a wall. You need to make sure that it has enough breathing space, and this means you can’t keep in a closed cupboard.

In case you are using a laptop, then put it on a flat surface with rubber feet, so that the air can pass under it. Don’t use it on a mattress or a blanket, because that is a bad idea.

Software Tweak

Control Fans on PC

When there are a lot of programs running on your PC, then the number of system resources being used will increase. These programs can make a PC heated, which would cause the fans to make more noises.

To keep the machine cool, close applications or uninstall them, if you are not using them daily.

You can decrease the number of applications that start, right when you open your PC. In simple words, it would be wrong to overburden your computer.

Adjusting Fan Settings

Adjusting Fan Settings

  • The first way to adjust fan settings on your PC is through BIOS.
  • BIOS stands for Basic Input Output System.
  • When you access BIOS, you can easily change the fan settings.
  • When you open your PC, a black screen will appear, where you are given the option to press a particular key, which will take you to the setup screen.
  • You have to be fast to press that key, or else the PC will load fully, and you might have to restart it again.

The screen will show you the following options (may differ as  per model):

  • Startup Menu.
  • F1 System Information.
  • F2 System Diagnostics.
  • F9 Boot Device Options.
  • F10 BIOS Setup.
  • F11 System Recovery.
  • Enter-Continue Startup.

From these options, you have to choose BIOS Setup, so press F10. This will take you to another screen, which will have basic information about your PC.

There is a system configuration option that the user should look for, use the arrow keys to navigate to that option, and then look for a setting that is related to PC fans. Usually, such a screen will have the following options:

  • Language.
  • Virtualization Technology.
  • Fan Always On.
  • Action Keys Mode.
  • Intel Smart Connect Technology.
  • Intel Rapid Start Technology.

Chose the fan always on option < and then press F10 to save and exit from the menu. When the PC reboots, the new changes will be executed, and hopefully, the fans won’t be as noisy as before.

Third-Party Software

Third-Party Software

If the above method is somehow confusing to you, then you can use third-party software to control the fans on the PC. This third party software will be particularly helpful for those, who have the BIOS option disabled on their PC. Download the SpeedFan software, because it is free software and gives a lot of control over the fans.

This is a powerful tool, and it can be a bit overwhelming to use at first if you don’t have the proper guide for it.

  • This software doesn’t have support for all motherboards, and you have to check if it supports yours before downloading it.
  • You can check its manual on Google, so that you don’t waste your time installing it, only to know that it doesn’t work on your PC.
  • The best part of this software is that it helps you control a fan’s speed just through one window.
  • Even if someone doesn’t have that much technical knowledge, they can still operate this software without fail.
  • When you see the control screen, there will be a list of fans on your computer, along with their RPM.

The GPU, HD, and CPU temperatures are the ones you should focus on and watch closely. Some things might not be labeled right or show the temperature in negative; this might happen if the value is not assigned to any component.

Adjusting Speed

You must learn about appropriate fan speeds, before adjusting them.

Adjusting Speed

This is because, if you set the temperature too low or too high, then that will impact the machine you are using. Nobody likes the sound of fans, but simply shutting them off is going to lead to overheating them.

When you set the temperature for your fans the first time, make sure you monitor the temperature closely and the performance of your PC as well.

If you see any abnormal changes, like the PC is not working as it used to, or is overheating, then you can adjust the temperature again.

Fans are very important for a PC, and even if they make noise, it is still important to have them. Clean the inside of your PC regularly, and make sure that you are not overloading it.

Should I run my PC fans faster?

Running the fans at full speed is better for your other components, as it will keep them cool.

This can shorten the life of the fans, especially if they are sleeveless fans.

What is the good fan speed of PC?

Well, I recommend the whole fan speed by 70c. Although 40c (104) is the start of the ramp, although I start, it is okay to raise the initial target to 37C, even if you adjust it where you hit 100% through 70c (158 F), depending on the fans.

How fast they take the ramp depends on how you decide the middle ground.

How can I control my computer fans?

Use the arrow keys on your keyboard to scroll from the BIOS menu to the submenu named “Monitor,” “Status” or something similar (this will also vary slightly by manufacturer).

Select the “Fan Speed ​​Control” option from the submenu to open the fan controls. Scroll down to the “Fan Speed ​​Control” section of the page.
