Yes it is. It is a 12 volt fan that runs off the lighting coil. It is relatively useless when running hoodless, but with the hood on it seems to move a little of that stagnant hot air away from the clutch area. It's not a cure all by any means but alot of infrared testing consistently showed a sheave and belt temperature drop of 10 to 15 degrees. I have a screen mounted directly above the fan with the hood on in an effort to suck a little cool air from a high to a low.
