I installed a 25mm fan on top of the ESC and it has definitely cooled temps down. I reversed the way the ESC mounts on the chassis, this cleared up some room for the fan to fit. I wired it directly to the receiver so as soon as I power up the Summit it comes on too.
MuchMore 25mm fan
I highly recommend it!
Are you running there standard fan or ultra high speed fan? The high speed flows quite alot!
The standard one. I use the same one on my Mamba Monster Max and its plenty to keep that one cool
where did you get this fan? is it called a muchmore?
