I have received all my parts to put together my new system P5Q-E Q9550 etc. except for my backplate for the motherboard. Is it ok to put together the system for a few days just using the pins with no backplate on this cooler? I've read that it does not actually need the backplate but have also read that you really do need it. I know if I install it this way I'll have to rip out the motherboard when the backplate comes to install it but really want to test my new setup. Is it difficult to remove the pushpins once they are installed?
