Cooling heatsink?

[Freemind777]

Anybody ever try running a cooling fan/heatsink for longer runtime on a handheld?

Using something like this?
RC Car Aluminum Heat Sink 540 550 Stock and Modified Motors Cooling Fan 7014B | eBay

Or this?
N10022 Aluminum Alloy Motor Heatsink w/ Fan for RC 540 / 550 Motor - Blue - Free Shipping - DealExtreme
