yeah you might have found it!
does the fan spin freely by hand? Even though your fan may be coming on, I wonder if its spinning at the designed RPM range- if its binding up at all, that might explain this whole thing
OR, you could have a bad/dirty connection to the fan that is showing up as a high resistance to the fan motor, which in turn will make the fan run slower. Fan relays are a suspect, but first I would check fan mechanical condition and connection to the fan motor
