You might need to change CPU fan speed without bios because sometimes, bios does not allow changing it.
In order to cool down your system when it is overheating, you will need to increase the fan speed. You need control over fan speed for other reasons as well as overheating. In some cases, you might need to use one of the methods described here in order to reduce your fans’ speed if they are running at full speed without any reason.

How to Modify CPU Fan Speed without Bios?
A BIOS setting that allows you to adjust CPU fan speed is one of the best ways to do so. Unfortunately, some BIOSes do not allow you to do so. In addition to BIOS, there are two other ways you can control your fans.
- Fan Control Software
- External Fan Controller
1.Using Fan Control Software
The various software that can control fans includes Corsair Link, Notebook FanControl, HWMonitor, Argus Monitor, SpeedFan, et al.
We will show you how to control your fan speed with SpeedFan today. Although it is a good idea to try out all of them.
Exactly what is SpeedFan?
The software can monitor fan speed and temperature of CPU components through Speed Fan, a free Microsoft Windows application. Manually controlling the fan speed is possible, as well as using the automatic fan speed feature that controls the speed based on the temperature of the components.
Note:
Step 1: Download & install SpeedFan.
Install SpeedFan by visiting this website. Open the application once it has been installed and downloaded. It will then scan your motherboard for all the buses once it has been launched.
Step 2: Configure fan control.
The first thing you should do is to configure the PWM controls so you don’t change the fan speed right away.
- You’ll find another window opening up once you click “Configure”.
- Select ‘Advanced’ now.
- You must then select “Chip” from the drop-down menu after clicking on “Advanced.”
- To find your PWMs, go to the menu and click on all the chip dropdown items (if you’re not sure where they are).
- Pick the ones you wish to control from your PWMs once they have been found.
- In the Set to dropdown, select either “Manual” or “Software-controlled.” After you select the PMW, you can change its settings.
- Please click on “Remember it” to save your settings. (Spedfan will be able to control your fans.)
- You can now view PWM1, PWM2, PWM3, PWM4, and PWM5, as you would see them in the main window. Change fan speed using the toggle buttons or manually typing the PWM settings you configured.
Step 3: Set up automatic fan control.
The speed of the fan is controlled manually in step 2. Speedfan can also automatically increase the fan speed when your CPU gets overheated and automatically lower it when it is cool.
If you click on “Configure”, click “Fan control” and check advanced fan control, the fan will run automatically.
2. Using External Fan Controller
You can use a fan controller to ensure that your fans are maximized via thermal paste and cooling, but you can also use a thermal paste and cooling system.
There are some motherboards that do not support Speedfan. If you have one of them, you can use a fan controller like the Cooler Master Hyper 212 or CORSAIR Commander PRO.
A pretty popular external fan controller, Cooler Master Hyper 212 looks classy because of its RGB colors. Six fans can be monitored simultaneously with its three-pin socket. You can see the temperature, fan speed, and other information on the device’s RGB LCD display. Six control knobs and six temperature sensors are also onboard, as well as a warning alarm.
FAQs about reducing or increasing CPU Fan Speed
- Can a Computer run without a graphics card?
- Can I connect Bookshelf speakers to my PC?
Games and video editing software that utilize the CPU heavily can increase CPU temperature and so computer fans start spinning at high RPMs to help cool the system.
Most computer fans run loud when they are dirty. It’s better to use compressed air cans, an electronic vacuum, or a damp cloth to clean computer fans. Dust can damage fan bearings, and they make loud noises. The Computer hope website has a guide for cleaning a computer system fan.
You can keep your PC fan speed between 50 and 70% when it is being casually used. In any case, when gaming, creating 3D models, or editing videos, your CPU can overheat. If the temperature reaches 60 – 70°C, set all the fans to 100%.
A heat sink or temperature sensor may be to blame if your CPU fans run continuously at full speed. Occasionally, this issue occurs due to faulty temperature sensors, but it can also be a result of processor-related problems.
