Wathai 120mm x 32mm ブロワー遠心ファン 110V 220V AC電源ファン 1232

This was a really good price and very quick delivery. I place this fan against the grill on the side of my freeze dryer to draw air through the machine and exhaust forward. It works excellent for that, moves a lot of air and is variable speed so on hot days when I need more cooling, I can just speed it up.

I have a large Samsung 30cf refrigerator in a built in in area with only 1/4" clearance on the sides and 1" clearance on the top available for ventilation. This was generating a lot of heat in the 8" area between the back wall and refrigerator. I mounted this horizontally under the cabinet by the back wall and top of refrigerator and and even running at about 7 volts it quietly exhausts plenty of hot air and keeps the compressor area cool. I am hoping a cooler compressor area will result in longer compressor life, time will tell.

Good for directional cooling small electronics. I use it for fpv drones.

Even at the lowest setting it makes too much noise...

This us great for what I needed. I use these to move air around inside my electric coolers just to make the temperature more even. I love how the variable speed option allows me to select how much air I move, like if I just put a large amount of warm items I can select higher airflow to cool items faster. Whereas if everything is cooled already I can select a lower speed to just move cold air from bottom to top.
