Was building my computer today with a friend and I was installing a hyper 212 evo cooler. I put a bit too much thermal paste (maybe 2 peas worth instead of 1), and when i pressed the cooler down on the processor, a tiny bit came out from between the cooler and the CPU and became visible. It didnt touch anything else, it just became visible. However, a very minuscule and extremely hard to notice amount dropped on the pcb of the CPU (top side, not near the pins).
My question is, should I worry about this? or am I fine?
Unless you are overclocking i wouldn't bother reapplying the thermal paste to be honest, you may see a few degrees increase with that amount of thermal paste but really with that cooler it should not be a problem.
