I just downloaded nTune, and was checking out my temps, and my CPU idle temps are at 53C!!!! thats HIGH seeing as i've read of people overclocking and running stress tests with it running at 50C! How can i fix this. Planning on re-seating the CPU but what about applying more thermal grease etc..? i used Arctic Silver 5 when i first put the rig together (about a week ago). I need something fast, because i have to RMA my graphics card, and that'll bring my PC down for ages, while the replacement gets here.... either that or i could fix it when the replacement arrives...
