Wathai 120mm x120 x 38mm 12V 2Pin Dual Ball 12cm Industrial Cooling Fan High Airflow

Great little fan. Moves a ton of air when you need it. Works with PWM 4 pin connector, but take note that this is a 2A fan. At 100% it will require a 2A pwm header, so make sure that your motherboard has one. For my MSI Tomahawk x870 board, I needed to use the CPU FAN header, which was the 2A header for my board. All other fan headers shared 1A.Make no mistake, if you're using this in your desktop It is very noisy above 50%.

Not quiet nor advertised as quiet but not terrible, especially if you use a temp control curve.Intakes a crazy amount of air and creates a lot of air pressure and velocity.Noise is not bad around 35%At 100% sounds like a jet turbine and feels like a wind tunnel, but youd probably not run at 100% unless your case temps are climbing

Okay, so, I've been using this thing for about a year and here are my thoughts.In order to use this, I bought a barrel-jack/fan connector and an adjustable fan controller that fits said barrel jack connector. Upon opening the box the first thing that you notice is the sheer girth of this unit. I mean, it feels much heavier than it should. The build quality is amazing and it runs like a top. at low speed its nearly silent and cools my mid-tower cpu case and heat-sink to a comfy 45c. I want whoever reads this to understand, I don't have a fan on my cpu heat-sink, this thing is connected to the front inside top of my case so as to suck fresh air in and blow it. It blows enough air, from that position to not only cool my heat-sink on its LOWEST setting but to also hit the fan in the back of the case. On medium, the fan sounds like what I imagine a duck hitting a airplanes turbine hears before it becomes meat shrapnel. It's just, Incredibly loud. Like, you can hear it 30+ feet away at half speed. The cooling performance though, matches the noise. I'm able to drop from 71c post Vulcan shader render to 42c in 20 seconds at half speed. Now comes the complicated part. Depending on the heatsink you use, There's little to no point in using this thing past half speed. Let me explain. The heatink can only throw so much heat, and this fan moves air so fast, after half speed, it reaches a point where it just doesn't remove any more. I am able to hold a paper towel to a wall at 3 feet from the back of my case at the fans full speed though lmao. Bottom line is, It's stupid, overkill, and I'm in love, buy three. Just don't forget the adapter and external fan controller, this may kill your power supply.

After looking at several RV and truck stores we found this one here in Amazon. It took a little longer than 2 days but it went right in and worked with the fridge. Very pleased.

The media could not be loaded. I built my pc with the purpose of it being a video editing/rendering system, so I stuffed in 2 GPUs, a Ryzen 7 with water cooling and 64 Gb of ram respectively. But overlooked the thermals and wondering why I was getting around 90c after a few hours. Figured out it was the front fans the AIO came with, so I swapped those puny little fans for 2 of these 5300 RPM big boy fans, and when I turn these fans up, the CPU will never go above 72c no matter how hard my computer tries. Not only do these fans push a ridiculous amount of air, they also give you a nice little audio cue to when they are working the hardest. They can also be extremely quiet when ran at lower speeds, only slightly louder than a regular case fan. Granted, they do sound like a hair dryer or a jet engine when they are at full power, but did a little noise ever hurt anyone? 100% recommend these fans to anyone who would like ice cold thermals and isn't bothered by a bit of noise.

No kidding around. These are fast fans. Literally sounds like my pc is about to take off down the runway. (When i first turn it on) good bearings and good hardware for mounting. Only thing is these are thick and not good for small areas.

Amazing airflow from this fan. Used to replace the malfunctioning fan in a magnavox mvh2000 heater. If youre getting the infamous E1 error code its most likely due to a bad fan. E1 means the unit is overheating due to insufficient airflow. This fan moves plenty of air out 9ft in front of the heater. For this application you have to create new mounting holes and swap the connector ends. Super simple upgrade that vastly improves the heaters performance. I must add that its not loud at all. Can hardly hear the fan when right next to my head. Installed with the heater in operation the only way you know its running is the warm air and the display readout. 👍👍 To help anyone out that might be working on the mvh2000, to remove the insert from the wood housing each caster has 1 extra long screw that passes through the wood into the metal. Slide the insert out and remove the side panel. The rest is self explanatory. Unplug the heater before any service to the unit. Be safe!

I got these fans for more air movement in my pc build. Plugged into my corsair h170 elite and the cooler died within days. I think the fans draw to much power and trip something inside the aio cooler I have them plugged up in a wall outlets so it's not drawing power from my system. Fans blow great otherwise don't turn it up to much or it I'll be noisey
