Anyone using the Q-fan control? I can enable in bios, reboot and the bios as well as Windows shows my CPU fan jumping from around -45000 RPM to 90000 RPM! Also, hardware monitor in bios hangs a little when moving through fields until I disable Q-fan and reboot. I also have a strange LAN problem. When I first installed board, I had no network connection. After trying for hours, I returned the board for a new one and all has been well except sometimes Windows will flash a "network cable unplugged" message for a second or two and then all works again. This on-off thing will continue sometimes for hours then quit. Any suggestions? My provider says all their tests show system OK. Thanks! (Board is Asus P4C800 Deluxe).
