We'll see what happens once the GPU starts dumping heat into the loop. I have 8 very low RPM fans on my two rads and I'm not swapping them out for noisier ones.
That is nice voltage. I'm at 1.33V ( I think, not at home to check). Nice little chips either way. Oh and my temps are almost identical to yours. Some cores do break the low 60s though. Hyperthreading is on.
