I water cooled my PC today. It does not leak, but I think I may have done something wrong. Before with the heat sink and fan I got about 30C on all cores Now I get about 28-30C on 2 cores (0 and 3) and 32-40 on 4 cores (1, 2, 4, and 5) I am using CPUID HWMonitor to watch the temps. It also jumps up about 20C under load. Not sure if I messed up on the thermal paste or if the block is does not sit on the CPU just right. I am getting ready to start overclocking my PC but I wanted to make sure the new cooling system would work correctly 1st. I will update my PC info for today's changes.
