Wathai 120mm 24V 2Pin DC Industrial Cooling Case Fan, 120x120x38mm, 3000RPM, 125CFM, 42dBA, For Desktop Laptop Server Inverter

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.

needed a fan for our RV fridge....works good

I purchased the Wathai 120mm x120 x 38mm 12V 2Pin Dual Ball 12cm Industrial Cooling Fan High Airflow It is an amazing Fan, Extremely powerful. I needed a more-than-usual powerful 12mm Fan, and this one is great. 4 STARS RATING BECAUSE: I rated 4 stars ONLY because the 2 pin conector (white plastic) has a "2 arrows" plastic lip/protruding the plastic surface that is not a common connection for Computers, so I had to cut it carefully making the surface flat. It should have a standard protruding safe-lock as other connectors, making it easier and more secure to connect and avoid a loose connection. Since I had to cut it (very carefully), I secured with gaffer tape the female connection at the end of the cable to the male connector from the extension cable that I used to connect to the computer, to avoid any risk of accidental disconnection. NOISE: since it's very powerful fan, you can't expect to be quiet using it at 100%. I have more quieter 12mm fans, but less powerful by far. This one is rated at 125CFM and compared to my 110CFM (that was noticeable quieter) it pushes LOT more airflow. So for my purpose I stored the quieter one and used this one instead. Since I use it for computer and it pushes so much air, I use an air filter, to avoid so much dust getting inside the case. Essential to me. There are many cheap plastic grills that include foam filters that can be easily unmounted and washed periodically (if it can be accessed from outside) SUMMARY: Great Powerful Fan.

Works well. Definitely moves air. Bought for my rv refrigerator to help vent air. It’s quiet and uses very little power and has now been running non stop for over 5 months. Definitely would recommend

I converted a 120 VAC space heater to 48VDC. I wired two of these fans in series to blow the hot air out. After several days of use, they're working great. A little loud, however, I think it's because they're mounted to thin metal.
