I just got all the parts for my new pc yesterday, and am currently putting it together. I've heard a lot about putting pressure on different parts, so I've come a problem. I'm trying to put my Zalman CNPS7000B on the processor. However, when I set it on the CPU, there is perhaps 3/8 of an inch between the retention braket and the nipples. I'm afraid to tighten it down like that, as I think there will be too much pressure on the processor. What should I do???
