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

Fits perfectly in my NeXTstation. You can only use the 2 Red and Black wires though on the 2-pin header as the speed sensor is not used.

Much quieter than my stock fans.

So quiet. Exactly what I was looking for. Used 4 of these to replace the stock fans in a Synology RS3412xs. Before replacing the Db was ~47-50 and now its around 32.

I got it to replace a 5 bay hotswap fan. This was way too weak or didnt have enough pressure because it caused my HD temps to skyrocket. Only use for case fans with no obstruction.

Good quality fans, they work well and the install is a snap. My old but very reliable Synology DS 411+ NAS drives fans started to sound a little noisy. I ordered two of these fans and they were for the most part drop in. Harness plugs fit directly into the mother board no problem. The only watch out is they are a little deeper. The extra thickness fits fine if you do not install the metal fan cage. Ive been using them a few weeks and everything is fine temperature wise. The other watch out is since these fans are not Synology exact replacements, you will get a beep code saying fans stop and start again. They never really stop though. You will have to disable the beep with a fan error in the software which is pretty easy.

You can tell by how much air is being moved that these are Noctua fans. As Noctua fans go, they are slightly louder than normal, but for a server rig that is out of sight out of mind. These are just fine.

Havent gotten a bad Noctua fan yet, and they last a long time.

I bought it to get a quieter case fan for my old computer and it is. Temperature is running fine after installation.

The best 80mm fan. Period.

Not impressed. I was hoping for more airflow. How hard is it to make a silent fan if it doesnt move much air? No overheating issues & a quieter HTPC so far.
