Active cooling for the ramps board?

[gmay3]

I was having problems running ~8 hour prints via pronterface - printer would just stop moving at a random point several hours in and stay hot. Pronterface showed a random "k" in the terminal. Research showed this problem is related to the ramps board getting too hot and disrupting serial communication.

Wow that's pretty wild. I haven't had a print go that long yet. I'm surprised that the little heatsinks haven't fallen off with all the expanding and contracting. I guess that little 3M double sided tape square provided with the heatsinks is pretty robust!
