No, the paste isnt here yet, i was jsut trying to put it on to see how hard it is before i do it with the paste..
It just seems hard i dont wanna break anything when trying to re attach it.
Sounds a sensible approach to me (IMG:

The main pain is holding the heatsink square whilst you do the clamps. GPU first, CPU 2nd.
The best way to do this is by resting the heatsink on a raised platform (block of wood etc) so that the mobo is being held in the air by the heatsink legs. Place the clamp in place making sure it's the right way around ... make sure that middle plastic bit is all lined up with the holes etc.
Now pressing just on the middle bit of the clamp - press BOTH arms diagonally opposite each other first until they snap over the legs. CHECK that they are securely in the grooves of the legs. Now do the remaining two arms - they will be tighter than the first two. Don;t be afraid to use a bit of pressure - just make sure you always do it on BOTH diagonally opposite arms at the same time - ie keep the pressure square. Double check all your clamp arms are in the heatsink leg grooves before proceeding to the CPU - same method, but this time you can remove the wooden block etc and just rest the heatsink on a table or whatever as it's the highest item on the board.
I hope this helps.
