Im planning to buy a Zalman 9500LED cpu cooler but I have one question before i go and buy it. Right now I have the Intel stock heatsink/fan from the E6750. So if i take out the Intel stock one, the thermalpaste will be left over on the cpu. I heard a lot of ppl say use the nail polish to clean it but will it damage the CPU? Cause I thought any water that touches the CPU will damage it? or?
