Very helpful guide! I replaced the GPU fan, got it all put back together, and freaked out a bit when it didn’t power on at all… then I realized there was an important note in the conclusion to PLUG IT IN first. Phew!

Very helpful instructions. However, Step 6 indicates that you should remove 5 screws, but really you only need the 2 on the left that are actually connecting the fan to the system board, the rest are unnecessary. In fact, the machine I replaced this on only had the one screw in the top-left.

Agreed 100%. Good thing I looked at this comment before I ran into major trouble. Thank you!
