Hi guys,

I recently built a system with a used E6300 with a Hyper 212 plus. I cleaned the E6300 surface best I could and installed the Hyper 212 plus with 3 lines of MX-2 in between the copper heatpipes. Tightened all screws. Heatsink is on securely.

The Vcore on this board is not adjustable and increasing the FSB does not seem to force an adjustment by the board. CPU-Z shows the voltage runs at 1.35V at idle, and at 100% load drops to 1.28 V.

Speedfan, Coretemp, Realtemp gives me different TJmax' of 100C, 95C, 90C for my E6300 SL9TA chip(Allendale?). No Idea which is correct but I can rule out 90C TJmax as idle temps would be about 1C-2C off ambient temp.

So instead of figuring out what was correct for this chip I decided to just check the difference in temp from idle to load with prime 95. I'm getting a difference in my core temps of 20C tops after 12 hours of prime 95 with stock CM hyper 212+ fan @ 2000 RPM. For reference, TJmax 100C at Full load peaked @ 54C.

Things I've noticed, as soon as I stop prime 95 the temp goes down 18C in seconds, the final 2C in a few minutes. And as soon as cpu is used the core temp shoots up quickly as well depending on CPU usage.

Is this acceptable difference from idle to 100% load? Or did I just screw up?

its normal to drop like that mine does that also.
you temps seem perfect to me

Thanks for the reassurance. :)  I guess I spoiled myself with my TRUE 120 and 45nm processor and thought something was up. :p
