Expecting lower noise from this than it gives. I compared it to a Gelid Silent 9 which I have and its noticeably louder at the same RPM. However, I used it over the Gelid as its PWM and can control it easier via Fan Xpert2. Call me lazy. In 'silent' or 'standard' mode its dead silent.

Replaced the fan included in the NH-L9x65 with this one to match my colour scheme. I I tried both fans though and performance-wise the included fan edges the redux one by 1c .

Quiet and Good Airflow. Only complaint is that it has a limited amount of accessories. I would expect accessories like cables and rubber mounts from Noctua.

Replaced the C7 fan with this. It's thicker (25mm) vs the C7 fan (14mm) and destroys it in cooling while being an order of magnitude quieter. This is a must-have for any air-cooled Node 202 build. It's possible you could get a smidge better performance out of the Noctua NF-A9 due to its 2000RPM max speed, but I prefer 1600RPM tops, so I'd use the low-noise adapter on that one anyway. This one is also black, which I wanted since you can see through the top of the Node 202. Be sure to put this in with zip ties that are rated for the temps the heatsink could experience, I used TR Industrial.

I just like the color of these. May look into getting Arctic fans only to match for of a black scheme!
