Wathai 120mm x 32mm 12V High Airflow DC Brushless Blower Fan for Radiator, Desktops, Gaming Consoles, TVs, Routers, Computers

Purchased to circulate the air in our RV fridge to help it cool everything down better. 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.

For a little fan it works like a big one technology how's its progressed over the years

Easy to install with great airflow. Used to cool Victron Energy 67ip 24v battery charger. It was not required but installed due to the small area where the charger is located.

Works really good

Was much quieter than I expected (which is great) since this is going into a retail display. 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.

This is a high quality fan. I am trying this style and another style to exhaust the warm air from my closed in shelf / 3-sided-box in a walk-in closet that I use as my wiring closet for Wi-Fi, home network, NAS and security video recorder. It is a solid fan but has three hardware shortcomings that the manufacturer should be correcting: 1) the screw holes on the 'back' side of the fan intended to mount the grill are NOT COUNTERSUNK despite the provided screws being intended for countersunk holes. It is ironic that the holes right next to them to mount this fan in a chassis are countersunk. 2) There are only two screws provided (although the instruction sheet says four), so it is presumed they are for the grill. That said, those screws are too long and project beyond the grill in what could be a dangerous length to catch skin depending on where the fan is mounted. So, I just took some simple SHEET METAL SCREWS I had on hand and screwed the grill directly to the housing. 3) Numerous buyers rightly complain that the thin wiring to the fan has no strain relief and could be torn free, particularly in the applications where it says this could be a blower for a BBQ or fireplace. I SOLVED that by applying a self-adhesive wire dressing clips I had on hand plus a the twist tie that was on the fan's cord. Looking forward to finding the right combination of (variable) fan speed and noise to exhaust the desired amount of heat.

I'm not sure if the fan is defective or if it just doesn't like the potentiometer I used, but it would only run at 12 volt with the potentiometer in line. If I reduced the voltage with the potentiometer the fan would cut off and the motor would get hot. I tested the fan on different voltages (5v, 6v, and 9v) without the potentiometer and it worked great. I tested the potentiometer with different fans and it worked just fine. Other than that issue the fan moves plenty of air, but it is a bit loud.

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.

Funciona muy bien, fácil de instalar, sólo reemplace el motor viejo por este y sin problemas mi inflable volvió a cobrar vida

No funciona

Great cooling fan for solar chargers. combined with the temperature monitoring to kick in at 32C and cool it down to 26C, works like a charm and has a very good air flow.

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