Alright, nothing is "fool" proof, but hopefully this helps. I've installed push pin coolers many, many, MANY times. I've even re-used push pin coolers many, many, MANY times. I've only ever had ONE problem (turned out it was just faulty aftermarket push pins, not stock Intel push pins). Other notes: The pins can be rotated 90°. If it is rotated counter-clockwise, it is in the OPEN position for removal from motherboard. If it is rotated clockwise, it is in the CLOSED position for installation on motherboard. When it is on the motherboard, the easiest way to rotate it is to use a slotted screwdriver. The method I use to get the clip into the motherboard mounting hole without the pin pushing down prematurely is to push down on it very slightly while wiggling it very slightly. It really helps to get ALL FOUR of the clips seated into the holes before pushing down on any of the pins. Also, push down the pins in a cross fashion (opposite corners). So, anyone think this is worthy of a sticky?
