The most you would have done with the screwdriver was scrape some paint off the board.
Now just screw the push pins onto the heatsink and pop it on there.
Lol, so quick question should I have the fan (blade side) facing towards the back of the pc or towards the front? Seems like the back would be best seeing as there is another fan on the back right where it would be... Or would it be best to be facing the front so it has a fan hitting on both sides?
