... and one is at 113C.
That's mental, something is wrong. Only mil-spec or special analog chips are designed to operate that high. Someone didn't put your waterblock on right, the temperature sensor is wrong, or it skipped QA altogether. I'm not saying you're wrong, I'm just worried for your sake.
It is more than one. If I could open the machine, I expect I could fix it. I cannot without voiding the warranty. I will RMA, but it is hashing well. Some have one board at 60-70C and the other at these temps. Likely bad pumps which is strange since the waterblock company surely does not have this kind of reject rate. Or a pinched tube etc.
