I put on my new Taisol hsf a couple days ago. I have no complaints, this thing is nice. Idle 28C. However, my full load temp seems to be changing. At first, it was around 45. But it has gone up by 1 every couple days. It seems to have leveled off at 48 now. Why would it do this? I'm using a taisol 742092 and heat sink compound from the shack. I also have 2 80mm fans, one in one out. Any ideas?
