I simply can't do it. I just installed my 2nd Core2Duo that uses the pushpin installation and once again I'm left one with one the pushpins shattered. So as a result I'm left with the processor not making as good of contact as it could. The little manual clearly stated that you do 2 pins at the same time (ones across from eachother), and then the other 2. No matter how I do it, 3 pins go in, 1 stays out. I'd spend 20 minutes trying it in every different combination possible to get it to fit, and then out of frustration I'd just force in the final one and it snaps. Anyone care to explain how to install these properly so I don't break my next heatsink too?
