I have a simple question really. I want to replace the stock NB heatsink on DFI LP DK P35 board. The heatsink is attched via couple of pushpins. Basically i'd like to know if can i use screws to attach the aftermarket heatsink instead of pushpins? Reason i ask is because i suspect that pushpins are being used for a reason: in order not to put too much pressure on the NB and i'm afraid that if i use screws that I may damage it. Can anyone clear this up for me?
