Computer processors have become extremely fast in the present day, and in order to control the temperature, users want a high-quality CPU cooler. These coolers’ fans can fail at any time, and many people are unsure how to replace them.
So, in this article, I’ll show you how to change the fan on a CPU cooler and what you need to know before doing so.

How to Replace the Fans on a CPU Cooler
To change the processor fan, just unscrew the bolts around the CPU using a screwdriver, then gently take out the fan from above the heatsink. Then, using a bolt of the exact size, install a replacement fan of the exact length, and secure the nuts until they are firmly attached.
A few factors should be considered before putting a new fan over the heatsink, as a CPU cooler is an absolute necessity.
First, ensure that you have the same fan size as the old one. You must also ensure that the fan’s connector supports the motherboard fan pin, or your freshly fitted fan will not function properly.
Here are the steps for changing the fan on a CPU cooler:
- Remove all of the nuts from the fan.
- Disconnect the fan’s power source from the motherboard.
- Remove the fan that is attached to the CPU cooler.
- Put the new fan above the heatsink.
- Secure the screws and make sure the fan is not moving.
- Plug the power cord from the motherboard into the fan.
After you’ve installed the fan, run a load testing on your processor and check the CPU temperature. If it gets too hot, check the fan connection and replace the thermal paste between the heatsink and the processor.
You should also clean the old Thermal Paste off your CPU and add a new one before mounting your CPU cooler. Because the new paste will transfer the heat more effectively.
Now that you have successfully replaced the fan let’s see what to do with your old CPU cooler.
Can You Use Other Fans as CPU Coolers?
Yes, you can use other fans as a CPU cooler, but the fan must match the size of the previous cooler, and the motherboard must support the connector. Also, ensure the fan can run at greater RMP because newer processors get quite hot and require more air pressure to cool down.
Since modern processors run at much faster memory clock speeds, they generate more heat than older generations of CPUs. A larger pressure fan would be required to cool down that much heat. So, if you want to replace your CPU fan, make sure you get a fan that can run at a higher RPM.
You should also ensure that the fan on your CPU cooler is the correct size. The cooler’s official website has the correct sizing chart.
For example, I use a Deepcool Gammaxx 400 CPU cooler. If I wanted to know the fan size my cooler supports, I could simply find out by going to the DeepCool website and searching for the cooler model I have. 
According to the webpage, my cooler supports 140 mm fan sizes. You may also determine the size of your cooler’s fan by following the same technique.
We can also get the cooler air flow rate and the cooler air pressure rate from the website specifications, which might be useful information for you while replacing your old cooler.

FAQs
Should I replace my CPU fan?
If your fan is broken or damaged, the answer is simple: replace it. If a fan appears to be functional, but the joints within it are worn out, it may still be experiencing rotor velocity issues and thus not performing well.
How long do CPU cooling fans last?
The majority of fans are rated for 25,000-45,000 hours of continuous usage, or 3.0-5.5 years. This does not, however, imply that all fans will survive the same period of time.
What causes CPU fan failure?
A CPU fan fault on startup is frequently triggered by physical damage to the fan, wrong settings, or external causes that cause the pc to overheat and cause the fan to run at abnormally high rates.
Conclusion
Although changing a CPU fan is not a simple process, it can save you from buying a new CPU cooler just to replace the fan.
