I've tried adjusting the multiplier and turning it down (to 6x, ~2.00 GHZ), and it operates at the same temp. I've reseated the cpu quite a few times. Not so funny thing is: even under 100% load it only jumps up about 3-4 degrees to about 63-64, even after 6 hrs running a full load stress test. :/ I would expect it to get quite a bit hotter if it was already running at such a high temperature, essentially doing nothing. I don't know what to make of it, should i return it? or assume all the readings are just inaccurate?
This proves to me that the sensors are not read correctly. I on the other hand tried to go from a 8-pin 12V to 4-pin 12V and only noticed roughly 2C difference (it fluctuates a lot and hard to get a good screen shot of it). If anything I noticed that Everest and Coretemps didn't always show the exact same temp readings as it did when I had the 8-pin 12V connection.
Both of these pics are stock using a 4-pin 12V connection. As you can see the idle temps are 40C-42C
This pic shows the E8400 stock using the 8-pin 12V connection as you can see the idle temps are roughly 4C-8C higher.
I always knew that using an 8-pin 12V connection may raise temps. However, it doesn't explain why the temps are higher then my E6850 which hovers in the early-mid 30C range.
