To have better efficiency and good performance of your whole operating system monitoring the speed of your fan matters a lot. As your processor fan runs at different speeds it helps to keep your device cool enough to do all tasks efficiently.
So in this blog, we will cover what should my CPU fan speed be. Can you control and monitor it or not?
What Should Be the CPU Fan Speed Be
There are many factors on which the speed of the processor fan depends. Typical CPU fan speed depends on the dimensions of a fan. Thanks to the lower RPMs larger fans are quieter as compared to smaller fans and rotate at a slower speed than smaller fans while pushing the same amount of air.
So let’s have a look at different ranges of processor fans depending on the size of the fan you have.
- 140mm fans 400 to 1200 RPM
- 120MM FANS 500 to 1500 RPM
- 92mm fans 600 to 2000 RPM
- 80MM fans 800 to 2500 RPM
A normal CPU fan can run at different ranges of speeds but can be in between 600 RPM TO 3000 RPM for a clear view, you can check it on a product page and user manual.
Therefore, ideal processor fan speed is a middle ground in between:
- Fan noise/wear
- Higher speed /RPM = cooler higher CPU performance
So there are diminishing returns to higher your fan RPM. If you double your CPU fan Rpm, a CPU won’t be cooled down twice.
This is due to the fact there is more than one factor to consider while calculating the processor fan speed. For making your processor cool, the radiators, ambient air pressure, thermal paste, heat spreader, and heat pipes are the important factors that play a vital role.
Moreover, a fan itself is an important factor or consideration.
According to my personal experience of many years of benchmarking and testing, the ideal CPU fan speed is halfway to two ⅔ of the maximum CPU fan RPM.
This factor will keep our processor cool while keeping it quiet.
Does CPU Fan Speed Really Matter
If you are worried about the health and performance of your processor you should pay attention to the speed of the fan.
If you are a PC gamer, a professional creative user, or a heavy PC user, and using your operating system at higher-end render workloads you should have optimal CPU fan speed that just gets you at higher performance.
If the speed of your processor fan is too high, you might face an engine-like noise which is no fun at all.
While if you are running sock CPU fans with higher RPM you need to replace them frequently. Also, you should clean them because they can collect dust and debris faster.
For better performance, you can overlock the processor fan so that’s why the processor can run much cooler and last longer too.
Similarly, you can replace your stock processor fan with something customized that can run at a higher RPM so you cannot face annoying noise.
How to check the speed of the CPU fan
There are many ways to check the speed at which the processor fan is running but the most common are the below ones:
Use of Software
To check the fan speed of the processor the most common way is to go for software as it can just read other sensors on your motherboard and offer helpful information on speeds, voltages, and temperatures. All these are within your operating systems.
Speed fans do this by reporting technology and monitoring analysis that works in your motherboard.
To use the speed fan:
- Download and install the app on your computer
- Open the app main window, and click on configure button
- Select the fan tab and select the CPU fan
Use of BIOS
The motherboard BIOS monitors and controls all fans of processors that are attached to them including the fans.
To access the BIOS:
- Shut down and restart your system
- Depending on the system brand you need to delete, Escape F2, F10, F11, and F12 to reach the BIOS MENU
- On the BIOS menu search for the BIOS settings that can be seen in the hardware monitor section.
- Here you can view the speed of the fan of your processor
Frequently Asked Questions
What should my CPU fan setting be?
For light PC use, you need to set the fan curve to a value that is pleasant concerning fan noise. While it keeps the fan and CPU at a comfortable temperature.
Should I run my CPU fan at full speed?
To run your CPU fan at a full or higher speed will cause a problem because the motors die before the bearings.
To wind up the blog what should my CPU fan speed be?
The typical good range of fan speed for your processor coms to be in between 600 to 3000 RPM. But you should check the user manual to have a clear picture of what conditions you ae allowed to run your processor at god speed and avoid damage.
