is it ok to run a 2wd buggy with no fan on the esc ?

[lodders127]

iv been running a 9t brushless system with 11.1v battery with a fan on the esc with a 7.2v limit
i got a new car and the first time i used it with the brushless on it the esc decided to catch fire and i think it might have something to do with the fan on 11.1v
would it be okay to use it with no fan on the esc on a 2wd buggy,im not driving it hard im just having a bit of fun with it realy.

the fan is probably only rated to 5 volts and running on a 2s lipo shortens its life anyway. Jumping to 11.1v will definately have cooked the fan, but you should be ok to run the esc without one as long as the airflow is good and you check temps after youve run it. 2wd doesnt put too much stress on the esc so id run it without mate

In general if you were going to use an esc without a fan, you would just keep checking the temperature to ensure it was not getting too hot (e.g >160 F).

You have destroyed your esc already though right? 11V though something designed for 7.2 V presumably would break it with or without a fan

my fault didnt read it right, thought it said fan was ok for 7.2v. If the esc can only handle 2s and you put a 3s lipo through it then it doesnt matter if a fan is there or not. It aint gonna work anymore

thanks for your help everyone and the esc can take 3s but the fan cant
it was stupid of me to use it realy with the fan like that

If you still want to run a fan, get one that'll plug into the battery port on the receiver. Then you'll have a fan, and it won't blow as it'll only run on about 5.5V.
