Before I wrote a single line of code for RealTemp, I did some initial testing with an E8400. CoreTemp assuming that TjMax=105C for my E8400 is wrong. I plan to re-install my E8400 next week and do a real thorough test. Previously, 35C measured with the Fluke 62 IR thermometer was being reported as 50C by CoreTemp.

RealTemp was only an idea during that previous test. Time for some pictures of RealTemp vs CoreTemp along side the IR thermometer and you can decide which program is giving you values closest to the truth.
