Greater than one weekI added two of these to a new build last week and they perform well. During Cinebench and IBT benchmarks, they ran at max and only gave a pleasant hum to let me know they were happily working. The rest of the time they were quiet. I will buy these again.

> 3 dayIve ordered 8 for two different builds. All, save one, run very quiet and move air efficiently through the case. The one fan Ive noticed has a very small, but annoying little whine that I have yet to pinpoint its source. Even so, I still want to buy more of these fans, as I like the way they look and how they work.

> 3 dayI wanted to add another fan to my Scythe Mugen 5 and this is the exact one to get. A little pricier than I prefer, but its an exact fit and works well. Make sure to get a 4 pin splitter in addition to this although it does come with a molex adapter. Ive noticed my 5800x tick down another 2 degrees under load with this added.

> 3 dayIve had these for a couple of months now. Out of curiosity, I set them to 100% and all I could hear was wooshing from the air.

Greater than one weekScythe has been my Go-To case fan for a while. I like slow & quiet. That being said, these are their slowest fan, and there is a limit to under-volting them. Specs say 300-1200 rpm, but they don’t start up reliably if running under 600. Still very happy with them.

> 3 dayI replaced two original 120 mm Corsair CPU water cooler radiator fans with these Scythe fans and drastically reduced the sound. The 4 wire control and my mainboard fan profiles allowed me to match CPU temperature to fan speed. In addition, I downloaded a free utility called Argus Monitor that also enables fan profiles and monitors all mainboard temperatures, which is super nice. If want a silent system, Get These Fans !!!!!!!!!!!!
