NoctuaNF-A20 5V PWM premium-quality quiet 200mm fan, brown

I bought this to make a diy air purifier from furnace filters and WOW it is quiet even at max power. Max power being 800 rpm but still, amazing. I just wish it didn't look like a prosthetic limb.

Tienda ya casi 2 años conectado a un cargador y funcionando al 100% es muy silencioso.

For years I have been hearing about Noctua fans and products, but I never actually owned one. This is my first fan and I am very impressed. I had a 200mm Thermaltake fan but it was making weird squeaky/rattling noises and it was not even that quiet at 800 RPM either, to be honest. I decided to splurge a little and go for Noctua - and it was definitely worth it. Noctua at full speed makes only a pure "whoosh" sound, no squeaking, no rattling, no whistling, no whine, no high-pitch noise; just a pleasant breeze-like whoosh throughout the PWM range. And I need to focus to even hear it at 800 RPM, while pushing more air than Thermaltake. Beautiful.Highly recommended.

Wie ich es von Noctua gewohnt bin, es funktioniert alles einwandfrei.

I bought two pcs for cooling of my av receiver. Now, avr works very cool.Fans are very quiet at middle level. Even at max level, you can hear them barely from seating position. So middle level is perfect and most silent level for cooling.
