Well, my Brand new Gigabyte Z77X-Up5-TH worked for one day. Today the CPU fan header and one Chasis Fan(System Fan3) header failed to work. My computer refused to boot up, most likely because it is not detecting an CPU fan. I have plugged in my CPU fan into System Fan header 2 & 4, also tried another PWM fan I have on all 4 headers in question. The result is the same, the fans would work on System Fan 2 &4, yet fail to start on CPU header and System Fan 3.Both 24 Pin and 8 Pin are plugged in, same goes for GPU(2 X 6pin). Detailed system spec in sig.

Fans tested on the headers:
Cooler Master Blademader 120 (0.32A, 12V)
Phantek PH-140TS( 0.24A, 12V)
Phantek PH-140TS 2X with a PWM splitter(2 fan on one PWM header, 0.48A total).

My diagnostic panel showing this figure: yes, only the right(top side) of the Port 80 panel is displaying. This is not anything the manual's debug code list.

Will get some more photos. The item was bought last week so I already filed for a Newegg RMA(replacement) and will be shipping to board out tomorrow. Just wanted to see if I made the correct diagnosis or if I missed something.

p.s most likely this is an hardware failure, I did clear CMOS and use back-up Bios(Main Bios is F11 I Q-flashed yesterday and worked fine, Back up is F4), neither resolved the situation

Phantek fans plugged into the 2 working Chasis header(System 2 & 4), the Blademaster 120(black) plugged into the CPU fan header-> both Phanteks works, the Blademaster doesn't even start.






Took a look at the board, no bent pins, probably will take a few photos tomorrow before I ship it out for RMA.
