Any RELIABLE sources for E8400/E3110 load temps?

Core temp 0.97.1 shows my E3110 as ~47c idle
Real Temp 2.24 Shows me as ~37c idle
SpeedFan 4.33 shows the cpu ~34c idle

I cant seem to find anyone that know s of an accurate core temperature monitoring program. Anyone found any good answers to checking core temps on these 45nm chips?

Thanks

Doesnt the current core temp show the Tjunction 10 degrees too low for the e8400s and the 3110? If that is the case then core temp will be 10 degrees too high. I similar temps as yours and in the current core temp they are always 10 degrees hotter than the real temp temps.

Both coretemp and realtemp are accurately reading the DTS sensor on your cpu, and both will accurately show the distance from throttling (distance from tjmax). Converting those relative temps (from prochot#) to absolute temps require knowing tjmax. Intel will not divulge tjmax of desktops, probably because intel has said they may change batch to batch (ie even for silent revisions?). Coretemp is guessing tjmax of 105, because 45nm mobile cpus have tjmax 105, but intel has stated that is INCORRECT. Realtemp is guessing tjmax as 95, which is an educated guess based on real measurements of casing temps at idle, underclocked, undervolted, steady state, that according to intel specs should result in a near equlibrium between core/casing temps, ie within 1-2C. So you are probably better off using realtemp with tjmax of 95. That might be 1-2C off, but no way, no how is tjmax 105C reported by coretemp. Speedfan 4.34 latest beta uses a tjmax of 100, which reads between coretemp and realtemp. Personally I use either realtemp or speedfan with -5C calibration, I use 95 tjmax for mine, as I think that is most accurate. But anything in 95-97 +/- 1 or 2 would be hard to argue with.

One more kinda related question - is there any way to put any load on the cpu in the bios? I just want to see what the bios temps show while i'm in there when the cpu isnt idling.
