The little giant industrial pump must be putting out enough EMI to interfere with the CPU's diode reading. With the pump running, the diode temperature is 41C (no power to system) while water is 27.03C for inlet and outlet of waterblock. Turn off the pump and water temps stay the same but diode temperatures drop to 26.9C (I haven't been running the system that long though and would expect the diode temp to rise to water temp over a long enough time.

So how can I shield this pump? I tried moving it away as far as possible but no go. I also tried plugging the pump and the PSU that is powering the diode reader into separate surge protectors. Made no difference.

Edit: ANother observation is that if I turn off the surge protector to shut off pump then the interference remains. I have to pull the pump's plug out of the socket for the temperature to return to normal. Weird
