Wathai EC 120mm x 25mm Ball DIY Cooling Ventilation Exhaust Fan 110V 115V 120V 220V 240V AC Axial Case Muffin Fan

Greetings, There are times when these little "muffin fans" can be real life savers! My aging computer has three such fans mounted inside to cool the system, but one has a dry bearing and going wonky. It is the most difficult fan to replace of the three, so I thought it would be prudent to add an additional fan to prevent heat damage to the power supply. I Gorilla glued the new 80x80x25mm fan outside the outer case, over an open grill, adjacent to the power supply. It pumps fresh air in through this grill. I give it five stars for an effective, temporary, "quick fix" with a darn good little fan! It comes boxed with "quick connect" wire clamps, mounting screws and a nice chrome grill-work. Got it up and running as fast as the glue dried. It is whisper quiet and works like a champ!

It works extremely well as an air extractor / circulator for a home made dehydrator. In fact it moves so much air that I had to reduce the size of the vent hole supplying it, this was easily done by placing a price of plastic partially over the hole I had already created. It has been operating reliable for months.

Needed some air flow for my treadmill, this little fan was perfect for the job. 120vac, tied into the power button on the treadmill turns on and off with the same switch as the treadmill.

I bought 2 of these to help cool an outside pond aerator pump. The pump is 1/2 horsepower and pumps air into our 1/4 farm pond and emits a ton of heat in the process. These fans and pump run 24/7 all year long and are in a wooden box that I built with 4 screened vents for air circulation. Both fans have been running nonstop for about 3 months now. So far so good and the aerator pump is staying much cooler which should help extend the pumps lifespan. (The pump cost about $500). These fans are affordable, easy to install, quiet and most importantly they move a lot of air! Would definitely recommend.

I needed a replacement fan for our counter-top water cooler in our kitchen. This is the exact same size and just a little higher FPM than the original, so our unit is now even more efficient. It is a tad louder, but we had become accustomed to the noise of the old dying fan. Hopefully this fan will work as long as the original which was 12 years!

I needed a small fan for a hot box I built to dry projects I worked on. This fit the bill and is able to provide proper level of air circulation without undo cooling affect. The noise level is just enough to remind me to turn it off when I am done using it. Installation was easy and build quality is good. Not worried about looks, I use it in a small shop.

Work really well

Looks decent, price is right, but it's loud. Unusable in an audio setup.

Worked as described, a little loud but moves a lot of air.

This fan work perfect. Almost silent and did a great job - cool down real fast.

I like that this thing can run on a range of voltages. I needed it to run off 220vac, to go with a homemade heater in my pump house, where that's all the voltage I have. It's working just fine, continuous duty. I had no trouble with it whatsoever. Between this and a PTC heater element, I saved a bunch compared to what a commercial 220vac heater would have cost. It's nice and quiet, just enough noise to know that it is on. Not disappointed!

This was purchased as a ventilation system for my chicken coop. Works well.

This product is being used in a smoking room and is not quite the size I wanted but it performs well…you should put the inches they are with the advertisement…I wanted a 4 inch square fan but this should do…
