Review: Quiet Powerhouse for Cooling Needs - Quiet Powerhouse for Cooling Needs This Wathai 120mm x 38mm 12V cooling fan has turned out to be a real workhorse in my setup. Right out of the box, it feels solid and well-built, and once running, it pushes a serious amount of air. The dual ball bearings are a big plus—they give the fan a longer life and let it run smoothly without the rattly noise that cheaper sleeve-bearing fans sometimes develop over time. I put this into a network cabinet where heat tends to build up, and the difference was immediate. Temperatures dropped several degrees, and the system stays much more stable under heavy use. It’s not whisper-quiet, but for the airflow it provides, the noise is a steady, low hum that blends into the background. Definitely not distracting in a garage, workshop, or server room environment. The 2-pin connector makes installation simple, though keep in mind you won’t get PWM speed control—this is either on or off. For most industrial or electronics cooling applications, that’s perfectly fine. Just make sure you have space for the extra thickness (38mm vs. the more common 25mm), since it moves more air partly because of that larger size. Bottom line: A durable, high-airflow cooling fan that trades speed control for sheer effectiveness. If you need reliable cooling power and don’t mind a bit of fan noise, this is a rock-solid choice.
Review: Superb airflow if you can tolerate the noise level - Amazing air output and noise level! I found operating it at a low 3-6 watts, it is moving as much air as most of my other 120mm fans. Crank it up to full power of 20+ watts and it's like facing a 30+ mph headwind. Thankfully I purchased a speed control to go with this. Unless you are mounting this fan inside a sound proof chamber you'll definitely need one to restrain the noise. I purchased this fan for cooling under my tractor canopy so the noise isn't that bad compared with the tractor diesel engine spinning 2500rpm. Most of the time I'm using the speed control at about 1/2 of maximum. But it's wonderful to crank it up when the outside temps are getting high. Size is correct match for 120mm mounting. The speed control I used is 4 pin version so fan connected right up. I haven't had any problems with operation. Get a speed control that permits setting a minimum speed also helps. Overall I am very, very pleased. I've bought several other Wathai fans and this one is just as well built as the others. I will definitely to buy Wathai fans.

## Questions & Answers

**Q: Is this unit ul tested, if yes, to what standard. if not, what standards has it been tested?**
A: UL 507 is the relevant standard for electric fans, however this fan was not tested by UL. 

Also important to note that UL Listed products are tested while UL Recognized products are not tested. Both levels require a direct marking on the part which means this fan has neither level. To be honest most fans at this price level are not going to be agency tested just because the target market is PC case fans, and the things UL tests for are not relevant to PC builders. 

The fan has CE certification which is just saying it won't burn your house down. CE doesn't check fans for performance; you're better off reading reviews than looking for agency approvals if this is a PC fan.

**Q: will this fan work with just pos & neg hooked up? do I need all for wires hooked up to work ? thanks**
A: Will work with just pos and neg.

**Q: If I plan to use more than 50% capacity of the 5300rpm model, would I  need to connect it to a controller/hub rated for more than 1amp per lane?**
A: I would make sure that which ever Fan Port you connect this High Airflow Fan that it will support the amperage stated in the specs of the fan.

**Q: Any water or dust resistance rating?  ip52, ip67?**
A: I do not see any water/dust proof rating printed, however, I use this fan as a range-top exhaust fan in suction mode, so all cooking steam & grease-laden fumes are drawn across/through the fan... daily.  Thus far, it has performed flawlessly, despite the harsh environment.  I recommend this fan.

### ⭐⭐⭐⭐⭐ Christ on a Cracker...
*by M***L on March 23, 2022*

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.
