Fortunately I am under water so no worried about heat or noise 
The directX errors only happen after 3+ hours and even then it's not guaranteed.
Also just ran GPU-Z to find the exact asic and discovered that my card was running in 8x 2.0 mode due to a soundcard in the other 16x PCIe slot. I put a PCI soundcard in instead and now it runs at 16x 2.0. Will this affect anything?
