Hi Srikanth, Which FAN are you talking about ? The CPU or GPU FAN ? I just installed the latest livna NVIDIA drivers for kernel 2.6.24-4.64 and I didn't notice any specific CPU FAN issue on my laptops ( hp nc8000 & hp nx7010 ) . The ATI Mobility Radeon 9600/9200 chipsets are not cooled by a specific fan. Most probably, this is different on your laptops. Could you please let us know which ATI chipsets are installed into your laptops ?

One thing i have noticed is that the Fan is always running on both laptops (Toshiba Tecra M5 and Averatec 7170). When i check for the CPU usage it is normally (with Compiz running) less than 3% and would obviously spike when any CPU intensive operations are performed. When the CPU is high the Fan is high with lot of noise. I am not sure but wondering how the Fan works in laptops which have embedded GPU and is there a way to control the Fan. Also, is Compiz the reason for such a behavior. I use livna's NVIDIA driver on Fedora 8. Thanks Srikanth
