It's coolant temp that's abnormally high here, not CPU temperature. The GPU outputs 400W of heat which all goes directly through the radiator. This theory seems to be correct seeing as GPU intensive things cause the coolant temp to rise this drastically, not CPU intensive applications.
I don't believe the coolant temp sensor is broken either. CPU temperatures (when coolant temps are ~60C and there is no CPU load) hover slightly above 60, around 65-70C. Idle CPU temps are around 40 for me and since there's no CPU load it must be the coolant warming the CPU up if that makes sense. The AIO led's start blinking red and the AIO goes into "fail-safe" mode (some icue thing), although I guess that just reads CPU and coolant temps as well. Radiator feels very hot to the touch.
