So I have found now that I completely loose PWM fan control with the SPM software loaded. This is BROKEN! I have disabled the software in windows for now.
Thermaltake - Please investigate why the SPM software is disabling PWM fan control for Corsair H series (Hydro) coolers. While the SPM software is running, it has a LOT of other applications that run with it, Hwinfo and more, and I suspect one of them is what is disabling the fan control on my H115i. When I stop the SPM software all control comes back.
