lm_sensors

i got tired of the continued disuse of my wintendo (aside from churning out seti units) so on monday i parted out my linux workstation and put everything in the significantly faster machine. after running at full load for a few days i set up lm_sensors today and noticed the temps to be pretty high. temp3 (cpu) was generating an alarm, but only by 2.5C. i'm waiting for a new heatsink to show up so now that i know what load temps are looking like i wanted to get an idea of what idle temps were with the stock HSF. i stopped boinc and waited an hour to see the ambient temps (temp1 and temp2) come down significantly from ~58C to ~40C, but the cpu temp stayed at 127.5C and never changed despite the fact that the heatsink had gone from physically painful to touch for longer than a few seconds to lukewarm. i opened the sides of the case and the ambient temps dropped another 3-5C while temp3 is still 127.5C. now i'm convinced that figure is completely unreliable.

i've searched google for setup tutorials to see if i missed a step, but also noticed that pretty much every site that uses this chip as an example gets the same 127.5C reading for temp3. a thread on debian's mailing list archives alluded to a way to get the right temp but the thread finished offline. i'm hoping it's not a problem with this particular winbond chip, but if it is it's listed as working fine everywhere i've found documentation and the tutorials that use it as an example don't say the scortching-hot cpu temp they clearly show to be an issue.

i'm wondering if anyone has lm_sensors experience with intel chipsets (i845) and namely the winbond w83627hf. with the other temps changing to varying conditions and the cpu temp not despite my best effort, i'm at a loss for what could be the issue.

for those who do have experiece it's a bit long, but my sensors.conf file is stock:
