My 3.06ghz northwood was running a bit warm(about 60c under load). I just got a new tube of artic silver 5, so I figured I would just go ahead and put a fresh coat on to see if it would bring the temps back down some. I took off the xp-120, and it pulled the cpu out with it. It bent some pins around the outside edge, but I straitend them out with a credit card. I cleaned off the old thermal paste using 91% isopropal from both the heatsink and the cpu. I waited a few minutes, then put on a fresh coat of AS5, re-installed the cpu and heatsink, then booted her up.
Was idling at 48c in the bios, which is about the same as it was before, so I went in to windows, and started a prime95 tourcher test to see if the load temps came down any. Instead, they were much higher. It went to the mid 50's almost instantly, and then kept climbing all the way up to 72c. I shut it down, so I could make sure the heatsink was on right and making good contact. I touched the heatpipes and they were very hot to the touch, and the heatsink was seated correctly.
I tried cleaning and re applying the thermal paste again, and same results. I tried 2 other thermal pastes, one that had come with the xp-120, and one that had come with a retail intel heatsink, same results. I tried the thermaltake heatsink I had in my other socket 478 PC, that has a 6000 rpm fan, and it idled a little cooler but still got up to 70c under load. I tried my old SLK-947u that I was originaly using on this motherboard, and same thing load temps in the 70's, and throttling.
I can't figure out why this thing is running so hot, nothing else in the system has changed, I still have good airflow, the ambient temp is the same, but the proccessor is overheating.
I have now removed the heatspreader from the CPU, only cutting one finger in the process lol, and now the load temps with the xp-120 have gone down to 65c. It's no longer throttling of course, but I can't figure out why it's running so hot. It's still seems to be making good contact as the base of the heatsink and the heatpipes are still hot to the touch while it's running. I'm not sure what else to do...
