I've just bougth an ASUS Z87-A mbo and I'm experimenting a bit with chassis fan configurations. What I spoted is whenever I connect a fan to CHA_FAN2 connector on the motherboard and go into BIOS to check temperatures I see a 5 degree celsius higher motherboard temperature then when nothing is connected on that connector. It does not matter how the fan is placed I even tried leaving it out of the case.
So the problem seems that just the fan drawing power from that connector has influence on temperature readings.
Is my motherboard faulty? Everything else seems to function perfectly fine. I connected all the fans now via other fan connectors and even the temperatures are now normal. So it seems I just have to avoid pluging fans into that fan connector. But it bothers me because it is a new board....
Did anyone else have any similar experience?
