Sure! Have to think about a nice flow.

I already found some 25 x 25mm or 30 x 30mm fans at an electronic supplier.

Is it possible to wire them directly to the input leads of the controller? Or will this have an impact on the performance??

I think I will mod my warrior. If it can be done clean I'll give it a try.
Expect pics when I'm done. I'm thinking of two small fans directly on the heatsink, covered with shrink. With some proper inlets as well as outlets, f'course.
