firefly does not requires cooling?

Echoa

When I get mine next week I'm gonna be setting up some decent air cooling for it and try for 2.5ghz. I have an unused desktop heatsink and some others from my old  GPUs I can rig up. Has anyone tried memory overclocking or seeing if we can do it? GPU too? I want to push this as far as I can c:

PS. Thought I recognized Cappy from somewhere, you in the radxa forums too right?
