It definately pushes quite abit of air around for a small fan but be aware that the fan speeds needed to be adjusted as it hits noisy levels from spike in rpm. 5-30% is around the sweet spot for me where it quiet but still smidge more audible than a noctua cpu low profile fan but stay within reasonable rpm

Too noisy for its size.

Despite the title, I didn't expect it to be quiet, really didn't. It's a small fan that pushes air, which is exactly what I needed.Yea, you can find small fans that run quiet, but they all seem to have a bit more depth to them. I needed something with minimal depth, and small.Fan does what it's supposed to do...it pushes air.Only complaint, it doesn't have a directional arrow, to let you know which side pushes/pulls air.

Really loud little fan. As soon as my case heated up even the slightest bit, it ramped up speed to the maximum amd drowned out my ac unit and other fans in the room. I also cut myself on the blade but like thats just from me being stupid and trying to move the case with it spinning, so no star removal for that or anything. It does move air but dont use it if you want silence

Loud AF but moves air better than most the 120mm I've seen.

The best you can get in the 60x60x10 size. It is the second one that's failed on me in five years. I wish that Qnap would change their design so you could use a 60x60x25 fan

I received a three pin fan, not the four as described. Sending back for a replacement.

Was trying to cool down my hard drive by active cooling it with this fan. However it was too noisy and with a high pitch. Even though I've tuned it down the rpm via PWM by my motherboard. Ended up buying another reputable brand that is not as noisy or high pitched.
