Helmet fans

[Richard_UK]

Would these make a good set up for helmet fans?

 

This for the power, two USB outs and on/off switch..

From what I can see it would just be a matter of sticking them in with a bit of Velcro and plug and go.

They'll work but it's not the cheapest or smallest way to do it.  Might be worth mocking up sizes too to test fit before ordering.  I say this as I know head size and bucket space varies a lot, what 1 person can fit another won't.

 

My set up is 2 cage fans, I think 40x20 but I have some 50x15s that would fit just as well.  These are wired through a small switch each to a single USB and a 2300mAh lipstick style USB battery.  Works great and lasts all day, but importantly is small as I have a massive head!

The helmet came with two 12v cage fans fitted and it's a very neat job but unfortunately they don't really work, I can barely feel a breeze from them. They're set up running on a 9v battery, I made up a 12v battery using four 3v button cells and tried running them on that but it didn't make a difference. Some good advice though thanks, I'll try mock fitting to see if there's space but should be okay as I don't have a particularly large head, and I'm bald too :-)

replace them with 5 volt fans and run AA batteries. Not only will they move more air, but the run time will be over 4 hours.
