Honestly the only reasons I could think of were for...

1) Fan longevity, a non running fan has less chance of breaking, and it’s sometimes super cold at the track to the point where you don’t need a fan, so I figured just push button it off to try and save it instead of taking it out or pulling the lead and leaving it loose in the buggy.

2) Being able to shut it off quickly so as not to wake the child and infant in my home when deciding to turn the car on when wrenching at home late at night. Figured a push button was faster in the case I forgot.

I guess when thinking about it now I know it’s probably a dumb idea but was just curious if anyone out there has done it.
