How
to fix the computer Fan is Not Working properly?
Method
1: Restart your computer
The CPU fan can easily be stopped
with a finger. To prevent the fan wiring from frying or any other damage, your
fan will stop spinning even if you remove your finger. Restart your computer to
clear this error.
Method
2: Clean your fan by blasting it with compressed air
Fans usually get clogged with dust.
The buildup could reach the fan blades and prevent them from spinning. You can
disassemble your fan and clean it. Make sure that your fan does not get to high
RPMs (Revolutions per minute) since it may damage the fan.
Method
3: Clear any wiring from the fan blades
Since CPU fans do not produce a lot
of torque, wiring going into the fan motor can block the blades from spinning.
Take down your fan and make sure that there are no wires. Secure the fan wiring
onto the side using epoxy to ensure they do get in the way of the fan blades.
Method
4: Reset/Flash your BIOS
Your BIOS controls your fan. Resting
it will clear any misconfigurations and get your fan working. To reset the
BIOS:
1.
Shut down your PC
2.
Press the power button and press F2 to enter into BIOS setup
3.
Press F9 to reset your BIOS
4.
Press Esc or F10 and select “save and Exit” press Enter and
allow your system to restart then check if the fan now works.
You can also reset your BIOS by
removing all power cables, battery, and removing the CMOS battery and pressing
the power button for 30 seconds.
Method
5: Replace your fan
If you have tested your fan on
another PC and it doesn’t work, then you will need to get a new fan.
Method
6: Replace your motherboard
The only sure way to know if your
motherboard is the problem is to test a working CPU fan on your PC. If it also
doesn’t spin, then you will need to replace your motherboard.
Make sure that your motherboard fits
with your power supply unit and other components or you will have extra costs
replacing the other components too.
Method
7: Replace your power supply unit
Desktop computers have a separate
power supply unit that supplies 3V, 5V,
10V and 12V to your motherboard. If the 5V or 12V supply is dead, your fan will
not work. This will therefore need your to replace the PSU.
Make sure that the PSU you are
getting has similar supply ports with your replacement PSU otherwise they will
not be compatible.
