If you enclose your fan, heat sink assembly you will have a huge increase in cooling capacity just make sure both fans aren't pushing against each other, and the air is flowing freely from one side of the cooling tube to the other,Cowardlyduck said:Here's a mod made to my Mini-E with 2 fans and a heat-sink.
Not sure how much heat it will remove, and it will be some time before I find out because of other work still to be done on my motor.
I'm hoping it will allow 4-5KW continuous without overheating.
The heat-sink is from E-bay: http://www.ebay.com.au/itm/121532652740?
The fans are Yeah Racing fans with 5.13CFM: http://www.rcmart.com/rc-yeah-racing-ya0201-tornado-high-speed-25x25mm-p-29521.html
They will probably get dirty/wet/muddy etc over time...but they are cheap, and that is why I have some spares.
I attached them with strong double sided tape for now. If it fails, I will probably just epoxy them.
The thermal paste is some of the best out there...for CPU's at least:http://www.ebay.com.au/itm/121405296689?
One of the other reasons I did this mod was I needed to reduce the voltage getting to the fans I'm going to be running inside my motor if I wanted to run them in series directly off a higher voltage battery.
This way I don't have to mess around with a DC-DC converter (again).
Cheers
But all that is assuming you're not mounting the controller in direct airflow, if you are I can't see those fans doing much at all apart from impeding airflow across the heat sink
