Wathai IP67 Waterproof 80mm x 25mm 12V Cooling DC Fan for RV Fridge Exhaust Ventilation Dual Ball High Speed DIY Cooler 12 v Fans 2 Pack

Only had this in use for 3 days, but it's 100% doing its job creating airflow through my RV'S LP fridge vents.I wish I'd thought to do this 2 years ago, adding airflow to a passive venting system has made a HUGE improvement in the fridge temperature in hot, 85° + days. The energy use is minimal, over 24 hours maybe 3/AH total.If the fan holds up as advertised IP67, and I did make a small "umbrella" above it anyway, and if it's good for 50,000 hours as spec'd, then it's perfect.It's got strong airflow, no issues with that.

Great price. These fans are super quiet and blow a good amount of air. Great product

Used the fans on my 5th-wheel RV refrigerator. The original fans were producing an annoying hum. The replacement fans were quieter but noticeably less air movement. They held up fine during a 9,000-mile road trip though.

These have really proven to be highly worthwhile for many custom applications and general fabrication of a massive variety of projects.The fans are quite strong for the small size but certainly draw a great deal of air. Their power consumption is minimal and the fan housing are strong and appear very well made.These two specific units are being utilized within a custom bug zapper, which helps to literally draw the insects into the electrical grid instead of waiting for them to eventually land on them. At approx. 4 inches, they'll do a terrific job and absolutely increase the bug zappers efficiency and overall performance.

perfecto gracias

Revised 3 weeks later: The fan stopped working. So I contacted the vendor and explained the application and asked what I believed was a simple question: “What is the recommended operating temperatures for this fan?”Several days later, instead of a simple answer I get another question. They asked, “what temperature is your refrigerator?”I answered of course, but what difference does it make? How does the operating temperature of my refrigerator impact the operating temperature of this model fan? Despite an immediate reply, a week or so has passed and they have not responded. Recommendation has changed accordingly.- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -I have a Sea Frost Air Cooled Ref/freezer. The plates are in the freezer (naturally) and “air flow” is the only way cold passes from the freezer to the refrigerator. They are side by side, with two openings between the sides. Bad design.Added one of these fans to the opening opposite of the center plate to draw air into the refrigerator. Works great. May have to add a way to adjust the speed of the fan to makes sure it doesn’t get too cold. But for now, that’s a nice problem to have.There is plenty of power in this little fan. Shame they don’t work more than 3 weeks.Poor life span, miserable service, there I can’t recommend them 👎🏽 Helpful? 👇🏽

I used these in my wine fridge. I put a cheaper brand in and it failed in a few months. So far..about a year in with these they are still going strong and quiet.

I used an external power source to power one up. The air flow was super low compared to other fans of the same size.They are super quiet however.
