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’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 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.

These fans sound almost like a drone when you run them at high speed, though not quite as loud as a drone. That being said, I dont need to run them at high speeds, as they give good airflow even at lower speeds. I have them running at about 30% or so, and they keep my AV equipment cool without any significant noise. I used two blowing air in near the bottom and two blowing air out at the top, and I can actually feel the airflow in various spots in my cabinet with my hand, even at that low speed. I can see these being useful for a wide variety of applications.

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.

I make my own method to cooldown the tube of CO2 Laser Engraver, and works perfect to me.

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.

4 Large PC Fans that can be assembled in various configurations with all the supplied Nuts, Bolts, Standoff feet, Rubber pads and connecting tabs.

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.

These fans have a speed controller that operates them smoothly. There is a little noise associated with them but not distracting to the user. When the 4 fans are all bolted together they move quite a volume of air that would be sufficient to keep most electronics operating and cool. The individual fans call for 12VDC as a power source and are configured as two fans per connection. There is ample hardware to mount these fans for use in most electronic racks.

Worked perfect for our customer in their new custom cabinet
