Hello, my MOBO is NEO2FR MS-7512, I put my X5460 in there. With the stock cooler, temp. while idle was around 65 degrees C, sometimes slightly under when the room gets cold. So I bought a used Arctic Freezer 7 pro to solve that issue, but now it's even worse, average temp. (idle) was around 75 C and the last two cores were even going above 80. I don't get understand why, this cooler is supposed to be good or at least better than stock.
