S8038-10K - Server Fan, 80x80x38 mm, 500–10000 RPM, PWM Regulated, 4-pin Connector, 12 V DC, Rack Cooling Fan - Black

Awesome fan, if you need something that moves a lot of air in an 80mm form factor, this is it. It can get pretty loud, but, at lower speeds its near silent, and still moves a lot of air for an 80mm fan. Using with a 3d printed shroud to cool an Nvidia tesla V100, and it does a fantastic job at cooling the inferno. I also like how it has smaller fan blades to cool the internals. A sticker is included to cover the inner blades, encase of a high dust environment. Would buy again.

This moves a ton of air. I hooked it up to a 12V power supply and it does draw right about 1.1A in free air. The amp draw goes up considerably when its fighting back pressure, so the motor is plenty powerful to maintain high air flow even when restricted. It's loud, but you knew that already if you're looking for fans in this category. It comes with a little sticker to cover up the inner fan blades for use in "dusty environments". I would be curious to know how critical the airflow over the motor windings are. I assume the dust is worse for the bearings than the temperature increase would affect the motor.

I cannot fault the fan for being noisy since it does not claim to be a quiet fan, and even at low speeds this moves a lot of air, but it there is a distinct whine that gets under my skin. Some people might not be bothered by it, but it is a deal breaker for me since the server is in a place that makes the noise ever present. If your server is in a place where you do not have to worry about noise, then I highly recommend this.

Very powerful 👏 🙌

These are great for my home media server. They are loud, but that was expected.

These blow! 2/10 would not recommend sticking your sausage in it. My server finally sounds like it is working hard with how much these succ! Overall 6.9/10.

very nice build quality, it's great

It's loud, powerful, and does what it's meant to do. The build is solid and strong.
