Im building a flashlight and i want to test if a fan in it would be a good idea but the flashlight is really small so i would need a motor thats smaller than 1 cm preferably. I found really good ones at maxon group but unless you order them in bulk(1000+ units) they cost like 400€. So do yall know anywhere i could find them? Thanks in advance! (Edit: Im a complete baffoon and forgot to specify that preferably i would need a water resistant fan. I assumed this because bldc motors without drivers are wter resistant)

Soooo turns out mouser had a classical unit conversion error so they wrote 28 times as much airflow than there actually is in the fan specs so im not going to use fans in my flashlight as 2 watts of cooling matters so little that if i just use convection it would cool more.

Hah! I totally didn't notice that. Good catch.
