These fans are great. They are quiet, aesthetically pleasing, have a great build quality, and the cable options are fantastic. I love that the main 4-pin cable is so short and comes with extension options. I couldn't be happier. At 1200 rpm, they aren't inaudible, but they are quiet that you don't notice them too much... and mine aren't even confined to a case. Super pleased with the purchase. Just note, the shipping time is pretty accurate... took a couple weeks to show up, but that's what was advertised, so no knock on the seller.

I really wasn't expecting much. Boy was I wrong. The build quality is, superb. The accessories packaged with it are great. You can even choose from a short cable or long or connect both for an extra long cable. The sleeving is impeccable.At it's max speed of 1500RPM, I can barely hear it. And the noise profile it makes is very pleasing. I purchased a Noctua fan at the same time and it's going back. It couldn't compete.I have this fan connected to the radiator on my 980 Ti Hybrid and it is much, much quieter than the stock fan that comes with it. In Fallout 4 and GTAV (my hottest games) it only reaches a max of 48C. With the stock fan, it would get to 46C, but at the cost of a looooot more noise.. Which defeats the purpose of a liquid cooled 980 Ti in my opinion.

For starters, the build quality of these fans is fantastic. Noise dampening sleeves and washers, as well as the mounting holes themselves help reduce vibration. I replaced my cpu heatsink fans with two of these, and the difference in sound is astounding. I'm getting relatively the same cooling but with so much less noise! The fan noise I DO hear is very mellow and low pitch/smooth whirring instead of vibrations, humming, ringing, or anything with a discernible pitch. Highly recommend these.

Great fan. I use it as my rear exhaust fan. It is incredibly quiet and can move air like a champ. If you are trying to build a silent running PC, this fan is a no brainer.
