E8400 temp & IP35 fan control

[int]

Yet another thread from me, but I need more help

I've seen a fair few threads around, discussing problems with E8400 temperature detection and what software is best to get a temp as accurate as possible. However there didn't actually seem to be a "victor". I'm using speedfan, coretemp, and the abit uguru that comes with the board. All of these are giving wildly different values (at idle 31, 45, 29 respectively).

Has anyone managed to work out what program is best for these CPUs?

Secondly, speedfan and uguru are (in my opinion) terrible at controlling fan speed. Are there any decent programs lurking about that has a properly functioning auto-adjust function?

e: Figured I'd throw another problem in here as it has some relevance to overclocking.
I've disabled the speedstepping for the cpu, however cpuz still shows x6 multipliers idling and x9 when under load. Is this just cpuz being picky or do I have to do more than disable ESID in the BIOS?

Aye, I had noticed the large gap (usually 8-10C) between both cores, the main CPU temp reading seem to be an average of the two cores.

Seems to be a huge problem with the E8400

Yeah I'm using real temp now as it seems to be the closest to my BIOS. However the difference in temperature between cores is getting ridiculous now. As I look at it now, Core #0 is 38c and Core #1 is 26. I've applied AS5 and reseated the heatsink a couple of times and it's still coming up with this huge difference. I'm tempted to take out the CPU and see if re-seating it will help.

Ack, wish I could replace the one I've got

e: I bought it under a fortnight ago too...

@nightwish: My sensors are both moving at 7, well within the expected range. I think the sensors are just duff.

I'm pretty sure a couple of the programs I've used take readings from the CPU socket as opposed to directly from the cores. My BIOS only shows a CPU reading, not a core reading and the uGuru software with this board reflects that reading.
