Summary: I had intended to use these as layer fans on my Rostock Max V2, but unfortunately, as other reviewers have pointed out, it simply does not have a lot of pushing power to it. It is, however, dead silent in its running - it might do well as a fan for a RAMBO or RAMPS board, or to cool stepper drivers...
Summary: I used these to replace the Cisco 2811's noisy fans in a lab environment. A few things for this application: 1) The 2811 expects 3 pins, so I have to jam this 2 pin molex into the power source 2) Without the third pin, the 2811 complains about low fan RPM (since the 3 pin is open) 3) The fan is...
Summary: Very pleased with the reduction in noise these have over the original factory installed ones. They were recommended by a coworker and I had my doubts, but WOW! surpassed any expectations I could have imagined! Whisper sound from freight train!
Summary: works as expected using it on a TAZ4 3D printer, my old fan burnt out... i cant even hear the fan going over the nuise of the printer. doesnt mean the fan is quiet, just quieter than the printer. anyways so far so good.
Does what it says on the tin, not strong enough for servers.

Summary: Purchased 4 of these to replace the noisy fans that came in my Nortel Baystack 5510 48 Port switch. The stock fans pushed 10.1CFM at 32.5dB, where these fans push 4.86 CFM at 19.56 dB. So yes, they make less noise, but sacrifice too much pushing power.
Summary: I'm probably an outlier, but mine vibrates a lot more that it should. I had to cut a piece of anti-vibration mat and mount it with that in between the can and the panel. I'd return it for a new one, but at $5 or so, is it really worth it?
Summary: Usage ===== This is 40mm x 20mm fan. I bought it to replace a loud fan in the Mini-ITX power supply in my home server. This is the common size fan for a Mini-ITX PSU. Noise ===== The fan is fairly quiet, but certainly not silent, I have built several very quiet home theater PCs and have experience...
Summary: This is a great fan! It worked just fine out of the box and is very quiet. This fan would be good for a lot of purposes, one of which being a small case-mounted cooling fan for a Raspberry Pi. So why did I give it 4 stars? I purchased two of these fans for my 3D printer.
