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

I have my AV Receiver set up inside a closed cabinet, and have blown two of them over the last four years due to excessive heat buildup. I meant to install a fan to help cool the cabinet when I bought my last receiver, but never got around to it. I recently paid the price. So I finally got my fan, and it works great!! I cut an opening in the back of the cabinet, and mounted the fan so its blowing the hot air out. Ive read some of the comments about excessive noise, but I disagree. If youre sitting right next to the fan, it is dead silent until you turn the speed control up to about the 1/3 mark. Then you start to hear the soft whooshing of the air being blown by the fan, but only if youre sitting right next to it. NO noise from the bearings whatsoever. The air noise does get progressively louder as you continue to adjust the fan speed upward, and is quite loud beyond the 50% mark. But never any mechanical noise from the fan at all! I have it set at just below 50%, and it has significantly cooled down the interior of the cabinet. Hoping my new receiver lasts a lot longer than 4 years!!! I would definitely recommend these fans!

I bought this to install in my living room console to vent the hot air generated by my PS4, which is tucked away inside a compartment with a closed and locked door to keep my one year old from getting into it. The only problem is that the heat buildup caused by running graphically intense games would quickly get the inside of the cabinet way too hot, posing a damage risk to the PS4. This was just the solution I needed. I measured and cut an opening in the thin backing material of the console cabinet and installed these fans to exhaust the hot air out, and left the on/off/speed control switch sitting on the surface of the console until I can rig up a thermal switch or add a smart outlet to control it.

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.

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.

These fans are solid, appear to be good quality. I got them for my greenhouse, so will have a more detailed review after next summer, and will update then. But in the meantime they do move quite a bit of air, so should help keep the greenhouse ventilated.

I got the fan for my bathroom air circulation, with these fan i can blow out the condensation after a hot shower, very easy to instal and the fan is also quiet, I LOVE IT !!!!

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.

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.

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.
