I bought the item in order to replace the factory fan in my Yongnuo 900 LED light, it works well. Very quiet and it comes in a very impressive package:)

Considering it was ordered from Ebay [and I have bank details to prove it,] why was it delivered from Amazon [ maybe causing me to have costs at my expence by signing up for Amazon Prime.] This is not acaptable and will report it to ambudsman if this does happen and let the ambudsman sort this matter out. This is not the first time it has happened.

Terrific! Worked to replace the noise fans in the BSS BLU-100 and worked like a charm! Thanks!!
I wish noctua would develop 24v fans to help all the owners of 3D printers which run off 24v… they only do 5 &12 which means additional buck converters or other shenanigans to attach them…
Nice and quiet, pretty easy replacement in my NVR. Decreased noise a lot, although did have to trim some venting on the NVR case that was creating additional noise
Recomended. Works very well.
By default the fan was pretty noisy, I think because it is small and has pretty high RPM. I plugged it via Fan Speed Reduction Cable and not the level of noise is barely hearable. The thing is expensive and it is not quite clear for me why the price is almost equal to some bigger fans.
Put fan in, it was louder than original.Save your money not worth the $16. 1"X1"
This fan is awesome, and, it has everything you need in the box, connectors, extension, everything. totaly worth its price.
