Hi all,

I'm having poblems to make my system turn cpu fan off when I turn my 
laptop on and the thermal temp is around 32-38 C.

I can say that cpu fan control is working ok as it turns on and off as 
the temperature gets 50-52 and goes down to 44-42.

I'd like to know if there is something I could do to turn my cpu fan off 
when I boot my laptop. Because it will only turns of when gets 50C and 
goes down to 42. Sometimes this may take too much time and I'd like to 
converv energy and noise :)

Thanks in advance.
