Recently many PC users are complaining that their PC fans are making a loud noise or running at higher RPM while playing games. On the other hand, some users complain about the opposite. Their CPU fan speed is lower even at higher CPU temperatures.
So the genuine question arises what is the recommended RPM or speed for CPU fan. Is there any specific range that a CPU fan must maintain.
In this article we are going to explain;
- What is the ideal CPU fan speed?
- Should I set CPU fan speed at 100%?
- Does CPU fan speed even matter
- Is 1000 – 1200 RPM is a normal CPU fan speed
Why would you increase your CPU fan Speed?
Before we explain what is the ideal CPU fan speed it’s important to explain why would you increase fan speed.
Honestly, it’s not a good idea to change the CPU fan speed. The fan settings must always be left to Auto mode. Mainly it’s the BIOS that handles fan control settings. The default fan control settings automatically sync when the CPU temperature rises.
The reason for being left to Auto is that you aren’t going to monitor the CPU temperature all the time. Even if you have the best PC temp monitoring tool, you clearly cannot watch it’s temp status when surfing or playing games.
If you do want a quieter computer, the best option is to invest in the best aftermarket CPU cooler. They are far superior to the standard CPU in cooling and quieter.
Those who still don’t want to buy CPU cooler they need to tweak their BIOS settings and can use software to change the PC fan speed. At the same time, they must put clear focus that this speed must remain at all times within normal limits.
What is the ideal CPU fan speed while playing games?
The idea of monitoring CPU fan speed only pops up in mind when you are playing games and you started hearing loud noisy fan sound.
That’s when most users get worries they instantly install fan control software to monitor Fan RPM.
While looking at the main window of any fan control program you might see fan RPM around 2000 to 3000. Is it normal CPU fan speed?
For gamers when their CPU temperature reaches 70C, setting RPM at 100% is the ideal CPU fan speed. At 50C to 55C the normal CPU fan speed should be around 50% of total RPM.
Then again those who have installed MSI Command Center to manually control PC fan speed. This tool sets CPU fan speed at different temperatures. For instance:
- 0-40 degrees: 20% fan speed
- 40-55 degrees: 20% – 35% fan speed
- 55-70 degrees: 35% – 60% fan speed
- 70-100 degrees: 60% – 85% fan speed
This fan speed range may seem ideal to you but it’s wrong. A good rule of thumb is that when your CPU temperature reaches 70C that when you need to take precautions and increase CPU fan speed to 100%.
Does PC Fan Speed even Matter?
Yes, a CPU fan is a very important hardware component that mainly focuses on preventing CPU overheating. It manages to speed accordingly to heat which builds up so to make ideal CPU temperature within the case. The CPU fan speed proves to be the two-edged sword for fan;
If the CPU fan runs at high RPM –
- CPU runs cooler at a normal temperature, life span increases, overclocking possibilities
- makes loud noise
- uses more power
- reduces the life span of the CPU fan
- Needs frequent cleaning
If Runs at a low RPM then –
- Remains quiet
- CPU overheats, shorter CPU life span, More possibility of malfunction at high temperatures.
- uses less electricity power
- Longer CPU life span
- less frequent cleaning
Should I set CPU Fan Speed at 100%?
- Ideal CPU fan speed highly depends upon the design of your PC case.
- The optimal fan speed of the CPU should be sufficient to prevent overheating and keep the temperature within its’ safe zone at full load.
- There are many CPU fan speed controller software such as SpeedFan, MSI Afterburner, and dozens of manufacturer-specific motherboard control panels that allow you to configure the fan speeds.
- Usually, these tools configure PC fan speed either at a fixed percentage of max speed or a curve based on the temperature readouts. The latter mode is more preferable than the former.
- When your CPU is at high temperature i.e 80C or more, the CPU fan speed should remain 100% constantly until CPU cools itself down.
- Below that range, you can decide for yourself – at idle CPU temperatures, the ideal CPU fan speed must remain low enough to reduce the noise.
Is 1000 – 1200 RPM is a normal CPU fan speed?
Most CPU fans run at the speed of 5000 RPM. In that case, the 1000 to 1200 RPM is a bit low if you want your system to be cool at once.
To efficiently cool down your PC the normal RPM for your CPU fan should be around 3000 to 4000 RPM. This is
Then again it all depends upon the size of the fan. The RPM range may vary for small and large CPU fans. For instance, small fans might run at 3000 to 4000 RPM and transfer the same amount of fresh air that a large fan does at 1000 to 2000RPM.
