So i might be thinking my random POST and OS freezes are due to the HSF becoming separated from the CPU heatspreader. now when i say "separated" what i mean is that the HSF is twistable in its clamps. pulling it outwards away from the CPU there's no give. so my question is, is this what is causing an over-heat causing a freeze in Windows? i'm using an Arctic Cooling Freezer Pro 7 HSF on an Intel QX6800. a couple of years ago i decided to lap both the CPU and the HSF copper base in an attempt to get it mirror smooth and efficiently transfer heat better. would the lapping have caused the gap that i'm experiencing when twisting the HSF, and would applying more TIM solve the problem?
