OS is xp-home SP3 with lots of updates, ATI-driver is 8.593.100.0/ CCC 10.2 (latest one for xp), graphic-BIOS is 008.017D.026.000.
Before starting ATITool GPU-Z just shows "Fan Speed 0%" on tab "Sensors", after it shows the Fan Speed I adjusted in ATITool.
Question for me is: why do I have to open ATITool to get the fan speed information in GPU-Z?
PS. There is another maybe interesting thing. When I use GPU-Z 0.5.8 I have the situation described above. When I use GPU-Z 0.6.7 it shows nothing concerning fan speed; after having started ATITool both show the fan speed.
