Mine is over 50C, which seems hot. I think the issue is I'm running 4 2GB sticks of OCZ Reapers. DDR3 1600. These are 1.9 V sticks and they pull it too. I'm running them at 1770, and this 2 ur old rig is still flying. But I think that means my Northbridge has to put out some serious power too. According to my mother board, North Bridge nominal is 1.259v and RAM nominal is 1.55. I have them set at 1.497 and 1.908 respectively. Crazy high? It's just air cooled, and my NorthBridge has been set to shut down in BIOS if it hits 80 C. Default was 90.

So my question is are these settings nuts? If I cut back on voltage, my RAM doesn't have enough and won't even make it to boot.
