Don’t need temp control in a refrigerator. Quiet and Easy installation, has really good fan speed and performs well enough to push air around. Review: Great little fan that works perfectly so far - Really happy with this little fan. I had an overheating issue with one of my marine amplifiers on my boat. The console doesn't get much in the way of airflow to help keep the amplifiers cool in our summer months here in Florida. I decided to try this inexpensive fan as an experiment to see if it could cure my overheat issues. Sure enough, it keeps my amp out of protection overheat mode! I was able to wire it through an unused accessory switch on the dash so I can turn on and off based on my audio usage. I've only used it for maybe 5-7 hours total so far. Hoping it can live in the outside salty environment for at least a year or so...maybe it'll surprise me and last multiple years. ## Features - 12V Blower Fan：Small and powerful，Perfect for DIY inflatable ,to cool amplifier ,Car Parts, Playtations, Rokus, TVs, receivers, mondems, routers, DVRs, Computers and other audio video electronics - DC Brushless Fan 12V：Rated Voltage:12V 1.0A; Speed: 3000RPM; Air flow: 38.5CFM; Noise:45dBA - Inflatable Blower Replacement：Bearing: Sleeve Bearing ; Life: 35000 hours; Connecter: XH2.54-2Pin; Cable Length: 25cm Or 10 inches - Inflatable Fan Replacement：You can cut the plug and have it powered by a 12v 2A adapter.

Probably fine for a 4 foot one. **Q: What in the minium dc volt operating range?** A: I'm using it at 6v and it is working perfectly for my purpose (Powered air respirator). Below 4.5v it struggles. **Q: Would this work on a Lenovo M720q tiny computer?** A: I used in an inflatable yard decoration. You would have to measure and check the requirements of your machine. **Q: I need to know which cable is positive and which is negative since they're both black cables? What voltage and amperage does this product run at?** A: This device is powered by 110vAC, so their is no "positive" and/or "negative" connection. As per the specifications in the AMAZON notes, "4w". ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good fan at a good price *by C***P on April 20, 2026* Purchased to circulate the air in our RV fridge to help it cool everything down better.

Came with mounting hardware and seem very well made. Was surprised at how much air it moved so meets our needs perfectly. Came well packaged and am running it with an eight double A batter pack so no external power needed. ## Frequently Bought Together - Wathai 120mm x 32mm 12V High Airflow DC Brushless Blower Fan for Radiator, Desktops, Gaming Consoles, TVs, Routers, Computers - Wathai 75mm x 30mm 12V Blower Cooling Fan Dual Ball 12 Volt DC Centrifugal Fan 2pin for Amplifier RV Fridge Computer Case Ventilation or Project Replacement Part kit - PANO-MOUNTS 12V DC Blower Fan 120x32mm (4.72") Brushless Exhaust High Airflow 3000RPM - 2-Pin Moisture-Proof Cooling Fan for Inflatable, Car Audio Amp --- ## 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.jp/products/135224236-wathai-120mm-x-32mm-12v-brushless-cooling-blower-fan-dc](https://www.desertcart.jp/products/135224236-wathai-120mm-x-32mm-12v-brushless-cooling-blower-fan-dc) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-31*
