Noctua NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown)

I understand why these fans cost what they do. Theyre absolutely silent running at 30% and lower, and still extremely quiet and pleasant sounding at higher RPMs (nice low pitch, no whining, and still very quiet). At 30% and lower, I cannot hear anything. I can feel the air hitting my eardrum if I stick my head in the case, but thats it. These fans are impeccable.

Awesome, just like my other Noctua fans. Silent Performer :-)

I have an 8 year old HP desktop computer that had a 92 mm Delta fan on the back that would not always start up. Since I have been using Noctua coolers & fans for the last 5-1/2 years I immediately found this Fan. The HP motherboard has a 3-pin fan header but the motherboard will soon be swapped out with a Ryzen based motherboard that has a 4-pin fan header.

Honestly I did not know what a quality fan was.........nice, nice , nice, ugly, but nice....

Works great, bought it as an add-on fan to my Noctua heat sink.

Doesnt go edge to edge, just covers the lit screen. Wont cover the full glass touch screen, wouldnt recommend.

Replaced my stock computer exhaust fan with this one. Easy to install and very quiet while being efficient at exhausting air out of my computer.

Excellent fan-super easy to install dropped my overall Temperature down by 10 degrees! Also this fan is decently quiet (About average when at full blast) with a great airflow.

Combined with a CRYORIG M9i cooler that replaced the old and dusty stock Intel cooler, this fan serves as an exhaust fan on the rear chassis. At max load with the most intensive transcoding x265 video tasks in Handbrake, the max rpm never exceeds 1300, and at idle and light web browsing, it hovers around 800 rpm. You simply do not hear it or feel any vibrations when its working when touching the case, but you can definitely feel the air coming out the rear exhaust of the case, keeping things nice and cool at 34-40 C and never above 70 C at max load. The difference it has made to the old Asus M11AD is like getting a new computer which operates so much more efficiently, especially with the added SSD boot drive from SK. Next Ill likely upgrade the PSU and Graphics Card in addition to another 92 mm fan mounted on the front of the case to keep things cool.

Nice and quiet. Pity about the color, carefully designed to not match any other computer hardware.
