I have a Vantec Thermoflow 92mm Double Ball Bearing Temperature Controlled Case Fan with a 3/4 pin connector. I plugged it into the PSU to max out the RPM. I Plugged it into the mobo as well to see what the RPM was at, and it said 1950rpm while it was connected to both PSU and MOBO. Its max RPM is 3100.
Is this just the motherboard taking control over RPM? I removed it from the mobo slot so it's only running off of PSU, but it says it is an auto sensor controlled case fan, which makes me worry that a sensor inside the fan is controlling RPM.
