I was wondering if 62 degress Celsius is too high for an AMD Duron 1 ghz? If so, what would be an acceptable temperature? The fan I got with the CPU is rated for an Athlon and was supplied to me by the computer store I purchased the MB and CPU from. I've noticed lately that my case is making a loud humming noise and I thought it was the CPU fan. However, it's running over 6K RPM, so I've narrowed it down to the fan in my power supply which kind of sucks since the case is less than a year old.
