I ran across small dc fans (0.5"x0.5"x0.25) in some CNC controllers and they might work great in flashlight sized hosts. I hope to lock down a vendor and price next week. You interested?

Regular 5-9vdc DC smallest fans I have ever seen in a finished package, and not just open blades.

lmao @ geckos

They look like normal every day little box fans except they are damn tiny. I hope the won't be expensive, but if they are a special part with low volume manufacturing.....well that's not cheap....

Small is beautiful in my eyes and those 20mm ones still come into, "too big for a handheld", territory for me.

The 5-9V is a bit of an obstacle but I guess they'd run on 3.7V, just not to capacity. I wouldn't want to be putting a driver in just for a fan!

I'd still be in for one or two of those 20mms anyway as I have a need...

As before, keep me posted!

Thanks guys.

I may be being stupid but why does it have 3 wire output? Direction control?

Very nice find Uranium. At close to $20, it's an expensive do-hickey but might be worth a punt for sh*ts and giggles.

I will be storing this info for later...

The third wire (yellow) is for when it's used in a computer.

It's the tachometer pin. It allows the motherboard and BIOS to monitor the fan's RPM.

I doubt you'll find a cheaper one.

Anyway, I just found my 5000rpm mini fan. I forgot how loud they were!

Ah, thanks some more... Guess it'll either be, 'ON', or, 'OFF', in our applications then! :D

well seeing those 20mm fans are great and if one was willing to cut them up a little i am sure you could get them to be around 15mm removing the outer ring, then its just a matter of gluing it to your heatsink and presto a super small fan cooled laser.
although at 20 mm and a bit of rounding the corners it would fit a good 1in heatsink
although for my personal one if i remember the inside is around 1.25 in so a 30mm fan might be better going to watch this.
