I have one running on the back side of my RV refrigerator to help dissipate heat and keep the cooling unit running more efficiently—a well-known upgrade for RV fridge performance that makes a noticeable difference, especially in hot weather. I also have another one exhausting heat out of my small shed, where it keeps the temperature more manageable during the summer months. In both applications it runs quietly, moves serious airflow for its size, and has been completely reliable without any issues. The 12V DC brushless design makes it easy to wire into a variety of setups, and the 2-pin connection is straightforward to work with for basic DIY installations. The 38mm depth gives it serious airflow performance for a 120mm fan, which is exactly what you need in demanding heat management applications. If you're looking for a dependable, high-airflow cooling fan for an RV, shed, solar cabinet, or any 12V application, this one is a smart, affordable choice that handles the job with ease. Highly recommended. 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. ## Features - Dimensions: 120x120x38 mm ( 4.72x4.72x1.5 in ) | Rated Voltage :12V 2.0 A| Noise: 60 dBA(Max) | Airflow: 230 CFM | Power: 22.8W | Speed: 5300 RPM | Air Pressure (In H2O): 1.17 ; 1 Piece fan include fan grill and mounting screws nuts - Dual-ball bearings have a lifespan of 67,000 hours and allows the fans to be laid flat or stand upright. 120 mm Case fan is designed to maximize airflow and can be too loud at full speed for some applications - High Speed: High static pressure 120mm fan designed for projects that requires cooling or ventilation; or as a replacement fan for various products such as antminer case , gaming PCs and mining rig, computer case - Connector: 4PIN; (+): Red Wire ; (-): Black Wire.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ So Many Uses – Running One on My RV Fridge and Another in My Shed *by J***N on April 12, 2026* So Many Uses – Running One on My RV Fridge and Another in My Shed This Wathai 120mm brushless cooling fan is a versatile, hardworking little fan that earns every bit of 5 stars and has proven useful in more ways than I expected.

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. ## Frequently Bought Together - Wathai 12038 120mm x 38mm PWM Computer PC Case Fan 12V 4pin 5300rpm 230 CFM High Airflow Duall Ball CFM FG DC Brushless Cooling Fan - Taidacent 2510-4P 3P Manual 4 Wires 0-5V 12V Fan Speed Controller PWM Speed Control On Off Switch for PC CPU Case Fan with Knob (Solder Connector with Plastic Black Knob) - Noctua NF-F12 iPPC 3000 PWM, Heavy Duty Cooling Fan, 4-Pin, 3000 RPM (120mm, Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/139075285-12038-120mm-x-38mm-pwm-computer-pc-case-fan-12v](https://www.desertcart.ae/products/139075285-12038-120mm-x-38mm-pwm-computer-pc-case-fan-12v) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-04-22*
