Does anyone know where to buy cheap 25mmx25mmx10mm fans?
In South-Africa yes, but not sure where you are, elaborating may help.
U.S., I’ve gone through AliExpress and eBay. I just want to expand my sources.
eBay and AliExpress are what I know for finding cheap sellers. Digikey and Mouser should have them, and very likely higher quality ones, but I’m sure they’re more expensive.
