So I can get a reasonable over clock to near enough 3.8ghz. I have managed 4.2 with a little voltage jump but still reasonable for the CPU. After a short time a short time a whine builds up and the vrm heatsinks get very hot. As soon as the CPU load drops and the load the whine goes away. Now would it be worth reapplying the thermal paste on the heatsinks? I know redoing paste on a gpu can have good results could I see similar gains? If I even get slight gains so that there's no whine under normal use only on full stress testing is it safe to the use?
Reapplication of TIM will have no impact on the whine. However you could cool the VRM better with a directed fan. Maybe something like the Antec Spot Cooler.
