Soo I fucked up. Badly.
So it was building a ryzen system in a corsair carbide air 240, and tried putting a r9 fury nitro from sapphire in there. It worked but was a very tight fit, and the window panel wouldn't
close - planned on buying low profile pci-e connectors. Thing is, I never got a signal on my monitor even though I knew the card worked.
Tried using different graphic cards, but because of the space limitation I had to unscrew the motherboard to remove/add the card. It was quite frustrating, because everything worked when the mobo was out of the case.
At some point I didn't give a shit anymore and tried getting the card out without removing the mobo - aaand as you may guess this is where things went south.
The heatsink of motherboard scraped the pcb of the card, short circuiting 2 pcb lanes. Since then the fans go full on blast whenever I give power to the machine (had another system available, same story). Only one displayport
gives a boot screen, but when the pc is fully booted all of them work. Tried manually changing the fan settings in afterburner, it changes nothing. What I did notice is that the system shows the fans being off (fan stop), so I figure
the commands of the card don't reach it's own fan controller.
So now to my question - is it possible to connect the fans of the Graphic card directly to the motherboard? I might buy a fan controller for the dvd bay with temperature sensors, if the voltage/connectors are compatible.
Other "solution" would be to water-cool the card.
Oh and you know why the system didn't work? The screw holding the hdd bay in place was creating a short-circuit on the motherboard -.-)
