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

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 purchased this a fan to vent a small room next to my sauna. It does an OK job, but just a little more noisy than I would have hoped for. I controlled this with a MOSFET and a 12V supply. Works great.

Used this fan to help cool the refrigerator coils in my trailer.
