AAB Cooling Super Silent Fan 4 - Silent and Efficient 40mm Fan with 4 Anti-vibration Pads | 12V Fan | PC Cooling | 3D Printer Fan | 4cm Fan

yes this fan is quite all you can hear is the airflow the fan itself is virtually soundless. they are excellent value and if you only need one fan it gives you two spares win win in my book

super quiet - in fact almost inaudible

For a brand marketed specifically to making quiet fans, it's not that quiet. Yes if you get these to say replace the annoying loud fans in a switch or server - these would be absolutely perfect as they're quiet enough to not be heard loudly when a cabinet or racks door is shut but if you are getting these for a desktop PC, there's too many quieter options than this to make them worth it. My noctua fan is quieter on full speed than this is on 70%.

Good quality and loves clean and pretty

I was pleased with how quiet these fans were. I used them on some network cards, that were ment for server use, hence needing air flow adding in a PC case.4 months on and they all need replacing. 2 have been on 24/7 and 1 for about 2 hours per day. I think I'll try those brown fans next.

I'm using two of these to ventilate my micro observatory. One sucks air in and the other pushes air out. Previously, condensation was forming inside, followed by black mould, but these are preventing the condensation from forming.

The connector isn't very clear in photo. I was needing a usb. It is a 3 pin connector. I will sort but buyers check your connection. Item well packed and feels well made but not tried out yet

Am using one of these in a solar powered water heater/diverter which diverts unused solar powers excess kws generated into the immersion heater which gives lots of free hotwater, the achilles heel of the diverter is the cooling solution, a cheep fan which jams repeatedly, wd40 worked for awhile but eventually it siezed, this fan was easy to fit and provides more cooling plus quieter, have spares should it fail? cool....
