    Hi

    I've finally gotten around to working on my control box. I didn't think everything through up front so it is a bit tight.

    So, how tight would you stack the drivers? I have a fairly powerful fan that push air towards them.

    What do you think about the following layout? To tight? I'm also considering removing the hood to improve airflow...

    Or am I just overthinking everything?

    Cheers,
    Andreas

    I have mine right next to each other (35mm spacing from mounting hole center to next ones mounting hole centers). Been running 3.0A high torque motors like that, just sitting in ambient air (no box) for 3+ years, no issues yet. They run quite cool. A 80mm fan blowing from the side over the heatsinks will do

    Thank you for your reply! I'll give it a try! Hopefully I won't fry anything.
