My 360 burned up

[Unsullied_Spy]

Microsoft wouldn't warranty it, so I did the X-Clamp fix to it and it boots up and runs now. The problem is that it still thinks it's overheating, I fired it up and did a quick test drive in Forza 2 and after 1-2 minutes the fans started speeding up again so I shut it down. I was testing it without it completely put back together but the fan shroud and everything was all attached, it was just missing the covers. I check the heatsink temp on the GPU and it was at 100 degrees (perfectly acceptable temperature for computer hardware) and the CPU didn't even feel warm so I didn't bother checking it. I still have the factory thermal pads on the RAM and they were at 95 degrees, so nothing was actually overheating. I took the shroud off to see if I could notice one of the fans not spinning right and they appear to be working just fine. It seems to me that the XBox is confused and just thinks that it's overheating when it really isn't. Any ideas?

EDIT: Appears to be fine now, I let it sit on the dashboard for a little bit and the GPU temp came up to about 100 degrees and stayed stable there. I played some Bankshot Billiards and it only hit 104, then a Terrorist Hunt in Rainbow Six: Vegas 2 got it up to 117 and still stable. I think it's ready to go back together now. Must have been the new thermal compound taking a little bit of time to set up.
