These AX-18 servos run a bit warm. I created some brackets and grills for some 30mm fans to assist in cooling the femur servos since they run the hottest.
In the first test the external temperature without a fan was 20 degrees F warmer after running for a few minutes. For now I wanted to see how loud 6 high speed fans would be.. turns out not too bad. Time to start some more extensive testing I'd say
