I have a pile of pictures from 50C to 75C that look a lot like the following two where RealTemp is tracking the IR gun pretty closely.





The picture in my previous post shows core0 and core1 tracking each other closely while core2 reports an idle temp 3C cooler. Perfect motivation for individual idle calibration for Quad cores.

I tried to move the IR thermometer a little left of center when testing to hopefully be over top of Core0 and 1 but this is far from an exact science. I'll be exchanging the camera for a small high speed fan tomorrow so I can do some more testing without the worry of controlling a fresh quad without a heatsink on it. The heatsink isn't attached at the moment so I can remove it, take some temps and then throw it back on to keep things from getting too out of control.

The difference in TjMax between RealTemp and CoreTemp is only 5C so it's not worth getting into an argument about test methods, theories etc. So far I don't see any evidence that warrants an increase in TjMax to 100C so I'll be leaving it at 95C. It will be interesting to see what my idle temps are with a HSF on it compared to room temperature.
