How to Change CPU Fan Speed without bios

How to Adjust CPU Fan Speed

Now that you know how to adjust CPU fan speed in two simple methods and now that we have learned that BIOS is a method of adjusting CPU fan speed, it is essential to mention that there are times when BIOS doesn’t work as expected.

This could be due to several system problems, which leads us to find other ways of changing CPU fan speed without using the BIOS method.

There are two (2) methods by which you can adjust the CPU fan speed without the BIOS, namely: fan control software and an external fan controller.

Using the Fan Control Software

Apart from using the BIOS control, fan control software for the CPU has been a good recommendation. This method has proven to be a convenient and accurate method of adjusting the CPU fan speed.

Fan control software is an easy way to adjust or control the CPU fan speed as it wastes no time in delivering it. This software method of CPU fan speeds regulates itself to the normal and best by adjusting the processor when hot and vice-versa.

Examples of fan control software are Speedfan, Real temp, H.W. Monitors, smcFanControl, etc.

Using the External Fan Controller

Another method on how to adjust the CPU fan speed without using the BIOS is the external fan controller.

This method is also known as the “manual fan control method.” It helps maintain your CPU temperature and manually start/stop or increase/decrease the fan speed accordingly.

With an external controller, there are a few things to keep in mind before choosing this method, such as its pin socket flexibility, how many fans can be monitored at once, its channels, and its controls.

Examples of external controllers include Corsair’s Commander Pro and Thermaltake Commander F6.

To make your computer fan run at its speed, check the R.P.M. frequently using the fan control software. If your P.C. fan starts making loud noises while running, it is probably because of dust or bearings.

Check-in with a professional if your fan speed and running problems do not subside after trying these classic methods to control the CPU fan speed on Windows 10.

CPU Fan Control

Your P.C. should be able to run its activities without having noisy fans distracting you. With CPU fan control, you will get adequate cooling even while performing intensive graphics card operations.

With the use of CPU fan control, you improve the cooling of electronics. You can connect your P.C.s to your motherboard. Unlike those on the motherboard, which are controllable according to temperature, those connected directly to the power supply may run only at a fixed speed. The method for controlling them will depend solely on how powerful they are. Take the side panels off your P.C. and have a look. It’s good to turn off the switch on the power supply (or at the wall) but leave the wire connected to the P.C. with a ground connection. You don’t want to damage anything with static electricity.

Fan Speed Controller

The fan speed controller is simple and can be controlled using a thyristor or transformer speed controller.

Thyristor Speed Control:

Thyristor speed controllers have high control efficiency and accuracy and provide easy manual motor speed and airflow control. It performs its operation based on output voltage control with a triacoltage regulator.

When operating in low-speed mode, the fans with thyristor speed control may generate an unusual noise, so the thyristor speed controllers are not recommended for low-speed applications. Low-voltage motor applications result in reducing bearing service life. The recommended speed control range is 60% to 100%.

 Transformer Speed Control.

The transformer speed control operation is on a five-step power transformer that regulates power supply voltage to the fan motors at a permanent voltage frequency.

Transformer controllers are for voltage-controlled motors. Several fans are connected to one power transformer if their total current does not exceed the maximum permissible controller current.

When operating in low-speed mode, the fans with transformer speed control generate no unusual noise. However, the continuous low-voltage operation mode can extend the motor bearings’ service life (speed 1 or 2).

Windows 7 Fan Speed Control

How to Adjust CPU Fan Speed

Before commencing on Windows 7 Fan Speed Control, you must turn off your P.C. before handling.

Windows 7 fan speed control. It is done manually by opening your CPU and using a controller that is close to your fan.

Fortunately, there are several ways to adjust your fan, and when people are searching for how to adjust CPU fan speed, they can easily pick which one of these methods best fits their budget.

You may choose to run it manually or automatically through the use of software and tools. While manual adjustment is cheaper and more affordable, it could be less effective and demand more time and energy to execute.
