    Cooling fan for MERV stock ESC ?

    Hey guys,

    Any recommendations and where to buy a cooling fan for the MERV stock ESC ?

    I think it has to be 25x25 or would a 30x30 fit ? also I'm not sure about the voltage. I've seen 3V, 5V and 10V versions out there of mini fans. I guess it needs to also have the right cable connections.

    Thank you !

    There are no fans that can fit under the MERV body and provide any worthwhile circulation to be of any benefit. So you will have to build your own solution.

    oh no ... I just measured my merv ESC heat sink and it's only 20x20mm Toyz only has 25x25mm in stock. That would be too big and hard to fit ?

    What size of the fan to use it more about what you are using to mount the fan. Do you have a solution for the fan mount?

    I ordered a 20x20x6mm since that's the size of the stock esc heat sink. Planning on using very thing wires tight around the esc if little screws doesn't work first

    Still waiting on the fan to arrive.

    For your motor's heat sink or stock ESC ? I am looking for one that fits the stock ESC heat sink.

    In case you used them for the stock ESC how did you mount it ? could you show pics ?

    Thank you !!!
