Wathai DC Centrifugal Fan 12V 75mm x 30mm Brushless Cooling Turbo Blower Fan 3 inch

Stuck this to the exhaust port on a 12v power supply and for is awesome. Almost silent compare to theInternal fan that it's shipped with and keeps every cool as a cucumber. 🥒

Very easy to use and these worked great for a mini ventilation system I was creating for my desk. I have not encountered any problem even with prolonged usage of 6-7 hours continuously. They pump good amount of air for their size and value. Overall really recommend for small projects.

Replaced two fans on my dtf printer. Straight forward installation. Quiet. Not super powerful, but does the job to hold the film in place while printing.

Works perfectly 👌

This fan is terrible. When I first plugged it in, it worked great, nice and quiet. Within 24 hours, it was screeching from the bearing making noise. This is not acceptable. I knew it was made in China when I bought it, but it seems impossible to get a quality fan like this that is this size. I guess I will try another random one, but it seems they are all from the same factory.Update 5/14. Thanks company contacted me to replace the product. They have sent a new product, I can at least give customer service a 5 star response, and am hopeful the new fan works better than the first broken one. If the new one works without issue I will update the review to 5 stars, but for now, I will stay at 3.

The media could not be loaded. I bought this fan to create more airflow for our fridge in our camper van. I am actually surprised at how much airflow this little fan creates. Not much sound coming from it either. I will do a follow up review after a couple months about the durability.

Fans initially appeared to be good quality, moved lots of air and were quiet. After a few weeks of operation both units I purchased started buzzing/vibrating badly and could not reach full speed. Upon inspection both fans had leaked/blown their internal lubrication out all over the place. These fans have sleeve bearings rather than ball bearings so without the lubricant they failed quickly. Very disappointed.

Used this in my 12 volt cooler. Moves the air around inside great. Have had it installed for several months and it’s still working great.

It's a 25mm fan, and the speed is even worse than Wathai's 15mm fan.Why is it like this?========================Update:The company quickly corrected their inventory and sincerely apologized for the wrong units with full refund. The third unit I got was a correct 30mm fan with output of 1240+ ft/min.

This time is not a replacement for Lumi. A lumi is 24 volt, and they are specific for the application of the device. For me no choice to go at the manufacturer directly.

I have a caravan refrigerator that seemed to be a bit variable in keeping all the contents cooled, due in part to a buildup of ice on the freezer plate.Based on the idea that domestic fridges use moving air to be frost-free and to make cooling uniform, I thought that I would try something similar with the van fridge - so I purchased this fan.I found a suitable mounting place in the bottom/rear of the fridge above the crisper drawer (blowing upwards towards the freezer plate) and wired it in with an inline switch to provide on/off control. This required a small hole to be drilled (with trepidation) in the fridge cabinet to run the power cable - along with a rubber grommet to prevent wire chafing and to ensure no impact on insulation.The final effect was in line with my expectations- the ice buildup on the freezer plate was substantially reduced and the temperature variation in the fridge was improved. The fan is very quiet and cannot be heard when the fridge door is closed. The fan runs 24/7 and draws negligible power. All in all this fan provided a noticeable improvement in the fridge performance and I am happy to put it down as a successful experiment.

stopped working after 7 months, real shame since it was great before it died,I want to add to my previous review, because the company contacted me and said they will replace the item which is fantastic customer service, but there is a small issue in that when I didn't hear anybody's response for over a week I threw the unit out so there is nothing to send back. I did just go online to buy another one because the last time I tried they were unavailable, but now they're available for $39 whereas I paid 17, ouch.
