2 Fans on Fanmate 2 Question

[Howie]

Hey guys, I bought a splitter and have two fans connected to a Fanmate 2. Speed Fan only shows one fan speed value. Does anyone know if the fan speed value shown by Speed Fan in this case is accurate? Not sure if something funky happens when you connect 2 fans rather than one to a Fanmate.

Anyone? Plugging two fans to one fanmate seems "quieter" even though the fan speed is shown higher than I normally have it. I suspect the fans are spinning slower than indicated but I'm not sure.
