I recently bought this server cabinet for the office. First time using a server cabinet. Wondering if anyone had fans they recommend that would fit this server cabinet. The less noise the better. I just have no idea what kind of fans to get or what brands are good. Any ideas would be great and very helpful!

I would look at the Noctua (https://noctua.at/) fans, they are the best cooling, performing fans, and are quiet.

also Corsair fans are also worth looking at.

But are these DC or AC fans ?

Do you also need fans in the cabinet ?

Unless the rack is completely full and you are having tempature issues you usually dont need extra fans in the rack.
Normally you cool the room and the fans in the servers pull the cool air through the server the heated air is pushed out the back of the server by it's internal fans.

Issue is the room is not on its own thermostat so if people are cold and turn up the heat the heat in the server room goes up which is terrible. Figured a few fans might help when that happens.

What is the temp of the room?

If you are using rack mount servers and equipment they are going to breathe front to back and additional cabinet fans will not make a difference. Also noise from the rack equipment will probably exceed noise from cabinet fans. Keeping a pool of cool air in front of the cabinet is the most important factor.

Thanks for the info guys!

Yeah, the servers will provide all the airflow needed. Rack servers are designed to be able to run with the rack full of equipment. They will push the hot air out the rear. It varies with the vendor, but equipment should be able to run with the inlet air temperature at 80 F, which is warmer than what most humans would want.
