Fan RPM is wrong or I don't get any

If you don’t get an RPM readout at all this can mean 2 things:

1. It could mean that no LM78 is detected. You can confirm this by looking if the Motherboard Temperature and the Voltage readout are also wrong. After version 3.3 this should no longer happen since the program will notify you when it can’t detect the LM78.
2. It could be that you do not have a 3 pin fan installed. You need to have a special 3 pin Fan installed and it should be connected to your motherboard.

If you get a fault RPM for a certain fan then try selecting another Fan Type on the Fan Tab.
