When the CLC liquid temp hit 44, i closed HWiNFO and reopened Flow Control. It immediately cranked the fans to 1800 RPM and the coolant temps started dropping (while keeping the stress software running).
That seems strange and unfortunate that HWiNFO is going to cap the CLC fan so low it wont dump enough heat to keep up with the CPU. I suppose if I never open FlowControl, then HWiNFO will keep the fans at 1500 - next question is whether 1500RPMs full-time is enough to keep up with stressed CPU.
So I shut down the machine and walked away for an hour.
Restarted PC, loaded HWiNFO (CLC Fan 1500RPM as predicted) and resumed stresstest (

Its been nearly 2 hours and the temp hasn't gone above 39.5. CPU temps still at a very nice 70-73 and the liquid steady around 38.5.
So I think this is a win. Especially since the case fans are all still running the 'smart' software to drive their effort since those are way noisier than the CLC fans.
