So, I updated the BIOS to 1304 and from out of nowhere the LED post code display is gone! It lights up and does the usual numbers on boot up, but then goes black (also does the reset button and flex key button too) when it gets to the windows load up...

So when I plu the 4 pin connector to the AIO header on my Maximus XI is says Fan Error when I start the computer. When I plug it into the CPU Fan header it works. Why is this? What can I do to make it work on the AIO Pump header?

MY Maximus Hero XI WiFi keeps showing code 40, but here is the issue......THE MANUAL SAYS NOTHING FOR CODE 40 IN THE CODES LIST! What are your thoughts on this?
