Fixes For An Acer Predator Helios 300 CPU Fan Not Spinning

Here is how you can fix a Predator Helios 300 CPU fan not working:

Restart Your Laptop

Before you try other fixes, you might want to restart your computer. A slight obstruction can cause your CPU fan to stop, and the only way to turn it on is to restart the PC.

Clear The Fan Dust

CPU fans are notorious for collecting dust on the blades. The dust can accumulate on the fan blades and prevent the fan from spinning. In that case, you should clean your fan to get rid of the dust.

The best way to clear the dust is to disassemble it and blow air through the fan. If you don’t want to disassemble the fan, squirt compressed air through the fan vents.

Re-oil the Fan bearings

The fan bearings must remain lubricated for the fan to spin. So, if the lubricant runs low, you’ll need to top it up.

In this case, you should use an electric lubricant spray to avoid damaging the fan or other parts. Just squirt a little lubricant on the bearings and check whether it will solve the problem.

Reset BIOS

Since the BIOS controls your CPU fan, you might want to perform a reset to ensure that the configurations are okay. Here is how to do it.

  • Shut Down Your Laptop
  • Press the power button and keep hitting the F2 button to enter the BIOS setup
  • Once the BIOS menu loads, navigate to Load Setup Defaults using the arrow keys
  • Hit Enter to begin resetting your BIOS
  • Save Your Changes to Exit BIOS

The laptop should restart with your CPU fan working normally

Check the Connections

If the CPU fan does not connect to the motherboard as required, you’ll definitely have problems.

You need to disconnect the fan carefully and reconnect it back to ensure there’s good contact between the connector and motherboard.

If you still can’t get your CPU fan to work, have it checked by a technician to determine whether it’s faulty. In case it cannot be repaired, you’ll have to purchase a new CPU fan and have the technician install it.

Final Thoughts

Once you determine that your CPU fan is not working, cease using the laptop until you get the problem fixed.

Also, if your Predator Helios 300 is still under warranty, take it back to an Acer Service Center to have the CPU fan replaced by the technicians.

Attempting to open the laptop and fix the fan can void the warranty. So never do it unless the warranty period has expired.
