2.2. CPU Overheat Error - Intel Fan

Sometimes a PC may give overheat warnings as well as make louder than normal fan noises.  This is generally caused by one of the CPU mounts popping loose.  To repair, follow these steps.

1) Remove power, open the side of the PC and locate the CPU fan.

2) Check to make sure the fan can spin freely with no wires or other obstacles blocking it.  If blocked, remove obstacle and retest.

3) If the fan passes the spin test, locate the four posts that surround the fan.  See below.

4) Make sure the screwdriver slot on all four post point to the center as shown.  If they point 90 degrees to the side, turn the post until it points to the center.

5) Look at the base of each post and make sure it sits flat on the motherboard.  See below.

If they do not look as above, or look like pictures below, the heatsink/fan will need to be remounted.  See remounting procedure.

 

6.  If all post are sitting correctly, press each one down.  You should hear an extra click when pressing one or more posts.  When the posts are completely down, they should have a little extra "bounce" when pressing on them.

Once you are sure all four posts are clicked down, replace the side, connect to power and test.  The temperature and noise levels should go back to normal.  If not, you may need to remount the heatsink/fan assembly
