Wderair 4 x 120mm Server Rack Mount Fan 12V with 100V - 240V AC Power Variable Speed Control, High Airflow for DIY Cooling Mining Rig, AV Cabinets, Home Theater, Refrigerator, Greenhouse

Im using this to cool off my lights on a deep aquarium. It has kept the temperatures down in the tank which I was having trouble with.

Installed on an open networking rack with the included hardware. The four fans span the rack perfectly and the holes line up with the rack holes. They thoughtfully included the clips to assemble the two fan sets together to make this possible. Easy plug and play from there, but boy are they loud when fully spun up. Just to be clear, most rack fans are loud. They maximize airflow over decibel levels. My other rack fans are actually computer fans that I select due to the low acoustic impact. I did feel I needed a bit more airflow at one point in the rack that gets rather warm. These fans do the trick. The speed controller helps me balance that decibel/airflow balance to the best effect. Quite pleased with them.

High quality fans with a variable speed controller. Note that when youre moving as much air as these three fans combined are capable of, theres going to be a bit of noise. It will help if you use foam tape or some other rubber- or compliant-mounting method that isolates these, and that will help ensure the least noise. Recommended.

OK. You want quiet fans that can move a lot of air? Check. You want 120mm fans that can REALLY move some air and dont care about fan noise? It has that too. You cannot complain with that at all. Variable controlled, not via software or through your UEFI (BIOS) but via your own two fingers.

Worked perfect for our customer in their new custom cabinet

These fans blow... but in a good way! It has a speed controller and is fairly quiet for 120mm fans. I set mine up on my desk to dry the hot glue that Im using for a sculpture Im creating. Theyre able to stand on their own even at 100% power, so I just place them on each side of the piece and leave it on as I work.

This is one of the most durable built from metal. adjustable speed and airflow fans I have used. This is a 4x120mm server rack fans 110v . I got this for my greenhouse but can be used for servers and cooling computer systems as well as many other uses. I am very impressed with this very nicely made fan ,a great price for this heavy duty built fan.

I’m on my laptop which is attached to my 4K monitor, I use a lot of demanding applications for work/ school. Although the fan on the laptop is good but it can only do so much and in fear of it crapping out on me and stopping my entire flow of work, I figured I’d give this a try. I got the two 120MM fans, bolted them together within two mins and was good to go! It comes with mounting brackets should you want to attach more fans. I love how it comes with the pegs legs should you want to lay it flat on a table. I love how it came with a dial which you can adjust the fan speed to your needs/liking. I was very surprised on how quiet it is. It does a fantastic job on pulling heat away from my laptop. I’ve noticed an improvement with performance as well. I’m very pleased with this, great for anyone who needs to keep their computer cool.

I ordered these to cool down some network appliances I have installed inside a closet. I have the 3 fans pulling air from a vent in the closet onto the appliances. They are extremely easy to install, just plug them in and dial in a speed. They can be configured to be completely silent to moderately noisy. Running these at their full speed is still lower volume then a server fan but audible from across a 20ft room at midnight. During the day running at full speed I could not hear these from across the room. Running these at a moderate speed produced enough air for my scenario and produced a very low audible volume.
