Do you think I could get away with pulling off the foam shim, or should I just leave it be; because after I tried to reseat it, it seems to be rubbing up against the chip set core...dampering my temperatures. They were 26 degress, celcius, and that was before I added Artic Silver 5. After they are around 30 and these are just the idle temps. I know that the foam shim is really making alot of un nescessary contact with the core and fore the looks of it its really starting to take its tool. I guess what I'm trying to ask here is: is the shim really needed, or will I crack the core if i take it off?
