It seems like uguru 1.05 is mixing up the temperatures.

abit eq in uguru 1.05 running in XP on a ip35 pro PCB 1.1 bios 14 does not show accurate temperatures; the values seem mis-assigned.
For example, abit eq shows
CPU 25 C
System 29 C
PWM 36 C

However, I measure ambient in the case of 25 C with a thermometer and the utility coretemp shows CPU temps of 36 C.

The negative effect is that FanEQ is getting the wrong temperature and the CPU fan is not speeding up when it should which is causing system instability.

For now, I dropped the FanEQ min temp to 25 C and its 100% fan temp to 32 C. I must say the Intel stock heatsink is quiet and seems sufficient to overclock a X3220 to 3 GHZ.
