at the GPU leaktest I had no rad in the loop at all (as you can probably see if you squint enough

) but I felt that the temps shouldn't have been so high regardless... the ambient was something 24C :ish
*edit* the temps were taken during that GPU leaktest. I'm probably just paranoid and the single block isn't enough to dissipate the heat generated by pump but somehow it sounds... odd. Makes me wonder how huge heatload it will add @ 24/7 which is how I'm planning to run it.
