On a cool race evening (60F and below) I ran the Mamba Max without a fan and it was fine. Since I am using a 1/10 scale ESC on a 8 pound buggy, I thought it would be a good idea to use a fan. I am geared fairly conservative (less than 40MPH). Even if the ESC doesn't thermally cutoff in the summer, MOSFETs are much happier running cooler (their on resistance is lower at lower temps).

I haven't run the buggy for a little while. I have been back to my first RC love.... airplanes. The Mamba Max with a 4 pole motor (Neu) is a little to coggy from a start right now. I hate to be sitting at the starting line with everyone else half way around the track. I could put 540C 9L Feigao back on..... maybe when I flip flop back from planes to cars again.
