Review: Works great - I tested only one so far, others are spare. Works great. Edit after futher testing : I have compared it to others fan of same size with respect to flow and static pressure. This blower is indeed the quietest but provides the lesser flow and pressure. I recommend it only if you need low noise and that you dont need big airflow performance. For 3D printer, if the airflow is not too much restricted and the fan not too far from the object to cool, it is totally fine. Direct blow without fancy air duct is best. In my application where i need the airflow pushed though a filter, this blower is too weak so i will use others.
Review: quiet and blowy but not much pressure - These turned out to be a little disappointing. They are reasonably quiet and blow fairly well but do not generate much pressure. I wanted them to blow down a flexible tube so I could blow sawdust away from the tool of a cnc. There is almost no flow at all after attaching the tube. fluid dynamics is out of my field but is suspect it is because the blades are flat and square. Maybe if they were more "spirally" they'd be better at making a decent head pressure. I may be being unrealistic but I wanted something quieter than a "compressor" - like lilo inflators. Maybe I can just mount this on the end of the tube and have it blow directly. Call me demanding but if I can blow silently down a tube I really don't see why China can't supply me with something electrical that does the same for under a fiver, delivered to my door, in under a week.

### ⭐⭐⭐⭐⭐ Quiet compared to stock ender 3 s1 fans lol
*by D***L on 10 April 2023*

i got these following NBR's guide on building his 5015 cooler for the ender 3 s1 3d printer. they are powerful and they have a good operating and noise range, at full speed they are loud but no where near as loud and annoying and ear butchering as the horrible stock 4010 fans on the ender 3 s1.
