I've personally compensated for these issues, but I thought I would help out and report what I have come across. Using the latest drivers, and going all of the way back to 2.6.3, the gl520sm-i2c-0-2d driver on my ECS K7AMA motherboard (using the i2c-ali1535 module), has always reported the fan speeds as twice their actual value. The other issue is that I have an ECS K7S5A motherboard, using the it87-isa-0290 driver (using the i2c-sis645 module), it seems to report the temperatures strangely. It is listing: Temp1/MB: +25C (min = +20C, max= +60C) Temp2/CPU: -126C (min = +20C, max = +60C) Temp3: +46C (min = +20C, max = +60C) So, it seems that my motherboard temp is 25C, and my CPU is at a whopping -126C. I'm not sure what Temp3 is.. :) I'm guessing it is reading something incorrectly.. Maybe, just maybe, the CPU is at 46C (it ususally ran higher with my older processor.. around 55C), but I would just be guessing. Thanks for the great software! I've been using it for some time, in combination with Cricket (cricket.sourceforge.net) and some modules I contributed, to monitor my systems! -Rich
