Noctua NF-R8 redux-1800, High Performance Cooling Fan, 3-Pin, 1800 RPM (80mm, Grey)

Well built, high-quality fan. It was my fault that I ordered the wrong size. I received the correct size and it works perfectly.

They out-perform any fan in its price range, and you get the material and build quality of Noctuas. Surprisingly quiet for the amount of airflow it provides, and arguably more aesthetically pleasing than regular Noctuas.

I compared this with a few other fans, and while this is quieter at a given voltage, its only because it isnt moving as much air as other fans. If thats a win for you, fine, but I want cooling. Noctua I have dismissed as hype after this observation. I didnt test these scientifically, but neither has a qualified independent lab to my knowledge. Returned.

I needed a quiet fan for a project I was working on but it needed to be able to move some air, this Noctua worked on both accounts.

Installed in my HTPC. Louder than expected, even at 1,600 RPMs. Pushes plenty of air. However, had to re-install my original Nexus 80 MM fans which were noticeably quieter. Note that this is not the PWM model so I used the motherboard RPM throttling. Nice design. Will use for out-of-the-way computers.

Excellent fans for rack servers. Quiet and really good airflow.

nothing outstanding

Really good for an 80mm fan. Quiet and powerful.

Used this fan as a quieter alternative to the Panasonic OEM on my HP oscilloscope. Seems to work fine, though the Noctuas Chinese plastic is noticeably thinner than the Panasonic Japanese made original.

At the highest speed, it is a little noisy, but that is to be expected from a smaller fan. This is still the most silent fan I have encountered at this size. It is worth every penny. Buy it.
