Radial 'blower' fans (sometimes referred to as 'centrifugal fans') are popular for many electronic scenarios including 3D printing, where they're regularly used as layer fans due to the higher pressure they can produce onto the printed part, cooling your filament quickly and efficiently.
This is a 24V 4020 blower fan, complete with a 150mm cable leading to a 2-pin XH2.54 connector.
Two 45mm hex bolts are included with washers (the manufacturer includes these even though we don't ask for them, so consider them a freebie! No nuts are included).
Like all blower fans, this fan isn't silent/quiet because it's not meant to be - blower fans are about moving air and getting the job done!
