The motherboard fan is making too much noise after the pc is turned off for more than a hour....the noise stops after pc is used for 20-25 minutes.
I have checked the temp and fan speed,
when making noise the temp is : 25 and fan speed is 1320
when not making noise the temp is :30 and fan speed is 1230
So, the problem is, the fan is making noise when temp is low???
i have never heard anything like this....
