I just turned this on for the first time and notice the fan is very loud. The fan seems to run at max speed regardless of the system load or temperature. A brief search on google shows even though there are options to control fan speed in BIOS, it doesn't work on this box.I plan to use this as a HTPC and the noise level is unacceptable for the use.  I'll see if I can hide it behind something to reduce the noise, if that doesn't work, I'm returning it.
