I would still like you clarify how slow they are turning. Are they just kind of jerking and not spinning at all? Are they turning like a big wind mill speed?
RPM=Rotations Per Minute. How many times the fan spins one circle in a minute. You might be able to see this data for some fans in the BIOS.
Yeah, please find this out as what might seem unusual to you is completely fine.
You can find it in the monitoring page of the BIOS.
Are the ones that are plugged into the MB spinning at the same rate as the ones on molex power?
