when i build my machine here shortly, i would like to know if is hould get a shim or not.

I have put plenty of fans and heatsinks on CPUs and have only had a problem with the one i am planning on puting in my machine.

The Thermaltake 2 or 6 is what i will put in, but they are a bitch to get it, the spring part is very high tention and i don't want to bust the core.

Any help would be great.
