Exactly this.
OP - Make sure that both rad fans are under "CPU temp" group. Once you have change that under RPM device set up, be sure save it under that profile then run p95 again and see if the fan curve you have set up works.
I have the same cooler and Corsair Link works fine.
thanks for the help Greybeard, have just tried this again on a clean install of Windows 7 and no change. All the other options work apart from custom curve.
Have the 3 pin connector from the pump connected to "CPU FAN" (4 pin) on the mobo.
Fan splitter cable (4pin) connected to both fans.
Link cable connected from the pump block to "USB header" CL software only shows 1 fan for the radiator, guessing this is correct?
