I just built my new pc last night, and I haven't had time to test like I wanted to. My question is I am using the XIGMATEK HDT-S963 to cool my E7200. I left the pc running last night and this morning using the motherboards temp it was reading 24C. can this be right. I always get very nervous when I have to install a heat sink. Also I came close to lapping it but with the exposed heat pipes I was thinking that it would be a bad idea, should I lapp it?
