QYN1225BSP

Works well. Used it in homebuilt phase change ac unit for work. Moves a lot of air, has good speed, but not a lot of torque. Small restrictions really limit its flow. But its quiet, does what I asked of it:-) voltage range from the little transformer says goes from 3 volts to 12v DC. Comes with little wire screens and spacers and some bolts with nuts.

Works great.

Nice and very cold breeze for cooling a btc node or a raspberry pi or a bitcoin miner

Works as expected, met or exceeded expectations.

Works fine for the money. Things like the wire grid protectors and the variable speed make it even more of a value.

Bought this to use with my offset smoker - sounds odd, but it works. I won't detail how I'm using this (like most of us barbequers we all have our secrets!).The item is well built, functions well, is quiet enough, and the variable speed controller is a must.Regardless of your application I do recommend this little fan - for it's size it produces good air flow and has a good price point.

moves alot of air, makes very little noise even on max.

Great little fan
