I do agree with you that there are problems with ASUS Probe, but this small utility software does a good job on reporting Temperature, Voltage, and fan speed. It is normal if you notice temperature increase in very short time after boot, this is the way it should be. Because I run my computer open case, so that I did touch the heatsink before and after boot, the temperature goes up really fast (or because I overclock?). There is a easy way if you don't trust ASUS Probe: shut down the PC until it cools down, now boot and get into BIOS, switch to hardware monitor, and leave like that for 15min. You should see how fast the temperature raises. On my PC, the temperature rais from 35c to 48c with a minute. In fact, the only way I can see 30c CPU temperature is to put the system into standby mode, until it becomes cold, wake it up and read the temperature. If you cannot make the CPU hotter (than 57c), there are few possibilities: 1) The tasks you run are not hard enough. eg, I don't get temperature differenc by running some of my games, or play MP3, use Office software..., but as soon as I run Q3, Specviewperf benchmark, 3Dmark 2000... the temperature goes up (those software runs at 100% CPU usage). 2) The heatsink and fan are doing a good job that they can blow the heat away from heatsink so fast that you don't have chance to see how hot it want when you were playing games. There is a easy way to verify this, set ASUS Probe to record temperature history. 3) There are something goes wrong, reinstall ASUS Probe.

I am beginning to believe that there's some "bad" monitoring going on with the ASUS probe utility. I was rooting around in the BIOS last night and came across the temp. reading under the power section and it reads: 48 degrees while the probe in Windows reads 57 degrees all at the same time. (Unless booting up into Windows raises the temp. by that much)...:-). Anyone know if these two readings are taking from the same probe/thermistor or what? Also immediately after boot up (30 sec maybe) the ASUs probe utility reads 50 degrees, which in my opinion should be more like 30, being more in line with the ambient room temperature . I have not been able to raise the CPU temp. by loading it , playing games, DVD's etc. does not increase its temperature at all.
