I have an ASUS P6T WS Professional motherboard mounted in a Thermaltake Armor+ case. The case has a fan on the front of the chassis that is functioning, but the rear fan behind the CPU heatsink (the red fan in the picture) and the transparent case side fan do not spin up. When I load the BIOS to look at the power configuration, it does not detect additional chassis fans. I have looked at the manual for both the motherboard and the case, cleaned both fans, and checked the wiring, and cannot figure out why these aren't running. I should note that the blue LED lights around the fan on the side of the case are lighting up.
BIOS "Power" screen:
ASUS utilities for this motherboard model are not available for my operating system (Windows 8.1). How can I figure out why these fans aren't running?
