Something seems odd to me. My cooling is in my sig. Before I got the P4 adapter plate for my water block, I was using an all copper CoolerMaster HSF. Load temps were 62 - 63C at 3415Mhz and 1.6V. Now, with my watercooling back up and running, my load temps are 42 - 43C with 1.65V at 3.6Ghz. The H20 temps seem very realistic to me... But, the aircooling temps seemed VERY high, I lost 20C between air and water. Does anyone use an HSF that uses the 4 holes in the board as opposed to the stock clip? Im wondering is there is an issue with the stock mounting mechanism in regards to the amount of pressure it is exerting on the CPU.
