Does anyone have ever had or read a problem about the CPU fan at boot?
I often need to reboot in the aim of the RPM CPU fan being detected properly.
It often happens when I boot for the first time of the day. I always shutdown the computer at night. I have tried with the power supply completely shutdown, and not shutdown, but it doesn't change.
My CPU fan is configured to work at 50% RPM, and when the problem happens, the CPU fan is not out of control, and keeps working at 50% RPM.
I have also checked the physical connection, it happears to be OK, so I really don't know why it happens...
