Depending on where blowers discharge, they can give you a way to do a sniff test on the engine room. Pretty important on the gas engines in case you get a fuel leak.
Blowers do virtually nothing to lower engine room temps while running, unless they are huge.
Only time I run mine is hot day after a run, with gennie on. Gennie elec end is air cooled and ER can get dang hot after a few hours.
