Ok well the cooler is working pretty well, not currently using flow control tho. My Maximus VIII Extreme bios QFan works better. Pump plugged into CPU_Fan header, fans off seperate header via splitter. 6700k @4.4ghz never going over 55c (25c idle), so might actually play with a lil more oc.
I have always had a problem with flow control not accurately reporting temps, it varies between 10-30c more than the bios temp sensor headers on the motherboard. Which is really weird to have that variance in this software vs bios, hwmonitor, etc. Makes for some really weird fan curves. Also when I was trying to use FlowControl the auto fan curve kept switching between cpu / coolant, and the evga sync color settings I had for (green/yellow/red) kept resetting back to the default blue/etc.
