I don't know if I'm missing something, but these heatsinks seem incredibly hard to install and remove. After messing with it for a while (and coming close to hitting my motherboard with the screwdriver a couple times) I was able to get it on. Recently I got my hands on some arctic silver 5 and was about to remove the heatsink and use AS5 instead, I found it very difficult and eventually gave up in fear of damaging my motherboard. The clip is extremely tight, and I don't see a way to easily get it to unclip. Any tips, possibly sites with pictures on how to do this? Thanks.
