I posted a couple of messages in another forum but no-one really replied so I am posting here in the hope that you guys are able to help me and save me from getting a complex
I have listed my BIOS config and system setup below in case that helps or incase anyone can offer recommended changes/improvements.
I have recently built my PC and I am now trying to understand the world of overclocking. I am a bit confused over a few matters (well everything really) and also confused with the results I have received when benchmarking as PCMark05 and 3DMark05 seem very inconsistent when testing. However, my biggest problem seems to be temprature related.
When I overclock the FSB (unlinked) to 320x10 CoreTemp shows an idle temprature at around 60 degrees and EVERYTHING ELSE (BIOS, ASUS Probe, ASUS AI Booster, FanSpeed & NVidia Temp Software) all show it around 40 degrees. EVERYONE tells me that CoreTemp is right and that everything else is wrong but I fail to see how that can be when my system is idle and I have a BigTyp cooler and an Antec900 case. My system/mobo temperatue is around 30 degrees.
When I stress all 4 cores of the CPU (SP2004x4) CoreTemp reaches tempartues or 120+ degrees and EVERYTHING ELSE around 75-85.
My voltage settings are all Auto in the BIOS except memory which I have set to 2.1V.
I have tried re-seating the BigTyp CPU cooler and opening the side of my case makes no real differece to the tempratues.
Even running my BigTyp at max rpm and turning my Antec case fans up to max only makes 1-2 degrees difference.
Can anyone help me or has anyone else had similar experiences??
Im too scared to try SP2004 on all cores for any length of time when its reporting 120 degrees
P.S. what are acceptable idle/stressed cpu tempratures anyhow??

I spent the evening last night runing through the guide to calibrate my tempratures but would now appreciate some assistance analysing the data.
I completed the calibration using an ambient temp of 26c (this was the lowest I could get).
I beleive I correctky identified the Tcase temp in Spedfan as there was only one Temp setting (other than the cores) that rose significantly when I ran SP2004. I renamed this to Tcase and had to offest this temprature by +1 to achieve a Tcase tempartue of 27c (Ambient + 1c).
Tjunction DTS Validation
Under idle conditions, I took the highest value of my cores (28c) and worked out the dec value for the hex value given using the RDMSR feature in Crystal CPUID. TJunction max is 100c for my CPU - result (57) = TJunction 43c
Tjunction Offset Correction
My hottest core was 28c. Tjunction hottest core should indicate Ambient + 10c +/- 3 (26c + 10c = 36c). I then offset all 3 cores by 8 (28c + 8 = 36c).
Was an ambient temprature for the test of 26c OK? I had all PC fans and CPU fan set to 100% and house was not hot!?
When I offset the Tjunction should I have used the (+ / - 3) adjustment at all?
I am confused why my Tcase and Coreo tempratures are so close when the CPU is under stress. Is this normal?
If you look at my Coreo temprature when the CPU is stressed at stock this reaches 65c in speedfan. If speedfan is correct this does not give me much headroom to OC. 5 degrees will be burnt up before I even reach 3GHz!?
I am still really confused why CoreTemp and Speedfan are showing different values and under stress the difference is a massive 12C. I appreciate under my adjuestments I have reduced this difference by some 8c at idle but surely these should be reading similar values now?????
