Default Too bad these micro fans aren't available anymore-edit, looks like Sunon still does

be kinda cool to make a heatsink/host with holes in it to draw air through . . .



Maybe these but they look a little big . . .



hmm . . . from Stokes . . .



Looks like Sunon is still making them . . .

I wonder what size (and type) fans are used in the Hercules- I'd guess centrifugal.

25mm is the smallest size you can get en masse. There's also 10mm and 15mm units for use in laptops- check on eBay or at specialty retailers.

Lots of little fans there, at good prices. Smallest is 20X20mm although. But at 1.2 CFM/9000RPM @5.0V, it pulls quite a bit (for a wee little thing)
Ramp it up to 8-9V and it will produce 2-3 CFM

Next step is if there's a self-contained solid state device that uses HV and ionic flow to move air with no moving parts, so nothing to wear out ever...

Default Was dreaming last night and thought a core i 7 heatsink

would be ideal and probably easy to fit into a D cell Maglite or even a bog standard plastic D cell flashlight. Figure out a way to hold your 18650 or whatever inside and there would be plenty of room for a larger fan . . .



actually fits perfectly into this plastic D cell flashlight . . .
