Fx 9590 with evga 1300w psu liquid cooled with great cooling, just upgraded the cooling, added a case cooler and next day gpu died, replace gpu and it overheats really fast, the north and south bridge are overheating while running spirit or even idle they are hitting 90c

The reason your mobos Northbridge heats up too much can be due to the heat pipe that ls linked to the VRM heatsink situates next to the CPU. Since you are using an FX9590 which is a 220W CPU it may me putting too much load to the mobos CPU power circuitry VRMs causing it to heat up a lot in turn transfer that heat through the heat pipe towards the Northbridge heatsink causing Northbridge chip to overheat. Since you are using liquid cooling for your CPU the mobos VRM heatsink may not be sufficiently getting air current for required cooling. To improve the situation you need to improve cooling inside the case. A fan directed towards VRM heatsink can make a lot of difference.

ASUS themselves recommends "Due to the high TDP, please be noted there are limitations while using this CPU(i.e. special thermal required..)"

So, update for you guys, I disabled Asus overhaul or whatever it was, it now isn't overheating but, I am getting a graphics failure where 1/2 the screen is blue and half is green over a windows failure screen, the fresh 'refurbished' gpu isn't working. Is my mobo shot
