i've seen the 41rpm as well. I think it might be poor grounding design by asus. does the case fan read 5000 in a different board?
AI Suite and Everest both. Everest won't even show the CPU temperature if AI Suite says it's high (dunno what's the limit).

I haven't tried the case fan on another system, but it's a high quality one, shouldn't have any problems reporting the correct readings.

To add more weirdness into all this... the readings are fine for a short while (could be minutes, could be days) after rebooting, but get out of scale afterwards. The readings have been correct for almost a year now and I just one day realized that they're off.

About PECI... no, haven't tried and from what I've read, it's the old, inaccurate way of reporting the readings, so I'd rather not use it.
