Hi. I'm just posting a URL for a micro blower that could be used for cooling high watt laser diodes. Murata Fans & Blowers | Mouser I got this from a friend. I'm going to try using this on a 1-watt blue laser diode. It's very small, but puts out a LOT of air! yet it's about 1"X1"X1/8" in size. It uses very little power unlike more conventional means. See what you think.
