I have a thermalright sk6 and when I install it one edge is resting on the upper ledge of the white zif socket. Is this right? The way it is designed with the clip it is impossible to put the heatsink entirely on the cpu. Thus the heatsink doesn't make contact with the core. This is my first system and I'm guessing that you have to have contact between the cpu and heatsink. What do I do? I will try to post pictures. Also, is it recommended to remove the pads and use just a plain shim?
