OC'd P4 1.6a stable, high temp reading??

[barkatraz]

Lil confused here. I've read all the post about what is a good temp reading for an OC'd P4. I installed my P4 1.6a on a MSI 845-ARU motherboard last night and bumped it to 2.4ghz on second reboot. Worked like a champ. I ran it for a few minutes and checked the temp and it showed ~28-30C. I was pretty ecstatic seeing that. I ran it all night and all today with no BSOD's or lock-ups. Again, I was ecstatic.
Feeling comfortable about the stability, i began the update process of the bios and drivers. The latest bios fixes the BIOS temp enabling it to read the correct temp. Now the BIOS temp shows ~42-44C and my PCIII Alert reads ~41-44C. Still stable.
Out of curiosity I decided to back the FSB down to 100Mhz and see what the difference would be. I am still registering the same temps even though I am not OC'd. Is this right? My vcore is set to 1.5v also (default setting). I was expecting a drop in temp. My case temp is ~25-29C.
By the way, on MBM5, what sensor should I be concerned with seeing on my gauges? I have sensor 1 to display Winbond 1. It is registering ~28C which is what PCIII Alert says my case is. If I switch it to Winbond 1 P2-diode it registers 127C (yikes).

i've noticed that overclocking doesn't seem to up my cpu temp readings much...maybe 1~2C difference at the most, and it's usually only noticeable at "full load"...differences in idle temps are almost non-existent

Use search and you find some discussions about incorrrect CPU temp readings with ARU board.
I have same problem reading CPU at 41-43C, when it is absolutely cold ($28C max)
My friend has temp showing at 15C - too low.
In MBM5 you can put offset for temp readings - I put -12C, and it reads correctly since.
I verified it using digital temp probe.

I think my p4 temp with newer bios of the msi aru was correct...I had 600mhz oc with about 1.6v and using retail hsf and theraml pad...I was getting 44c idle when room was cooler....

Now I use an avc sunflower w/ as2 and my idle is at 38c...so I think it was accurate...my full load swing was high on the msi ultra during prime but that could be the effect of the 2700rpm fan of the retail heatsink and the thermal pad....

I went ahead and bought a Sunflower HSF. I'lll let you know what I end up with!
