KEYFANCLUB 2-Pack 120mm Fan DC 12V Computer Fan 120mm x120mm x 25mm 2-Pin High Performance Cooling Fan

I have an incubator for poultry eggs that was making a horrendous noise because one of the blades broke off one of the fans in it. The fan is 120mm x 120mm with an unusually long (roughly 16") two-wire power lead. The replacement fan (one of two in the pack) has a shorter lead (11.8" per the specs), but is long enough to work in this application. Installation of these fans would be simple if they were being put into a computer case, as I've done many times before. With the incubator however, disassembly of the unit was necessary, and that included removal of hot glue (or something similar) that was used to secure all the wiring in place in the unit. The wiring was not only for the fans, but also for the temperature and humidity sensors, the automatic egg turner, and the heater. This made the installation far more difficult than it might have otherwise been. Once a significant amount of the hot glue was removed, it allowed enough space for the fan connector to fit through the opening between the controls and the main unit. This allowed me to remove the old fan and install the new fan in its place. Because these fans came with grilles, I installed the grilles in front of the fans to prevent something sticking into the blade, which I believe is why my first fan failed. With the new fan and both grilles installed, I was able to secure the wiring in place so the heating element (which is basically like a string) would stay taut, so it would function properly. I was then able to reassemble the rest of the incubator and test everything to make sure it was working correctly. Success! After the successful replacement of the fan, the incubator is once again working quietly as it did when new. The replacement fan worked well in this application, and if I ever need to replace another, I still have a spare.

Nice fans. Used to supplement cooling on a RV evaporation refrigerator. When running I can not hear these fans.

Nice size, great fan speed and quiet

Work perfect as intended, I used them to cool off an amp and they worked like a charm. They pull heat away, but you could use them to blow air as well.

These fans are so quiet. I used one to vent the aera under the bed in our 5th wheel to avoid moisture buildup and can barely hear it running when we go to bed. The other is helping to vent the back of the refrigerator out the top vent, I have to get up close to make sure it's running. The refrigerator fan has been running continuously for 9 months.

Great price for 2 of them...... I have purchased many of them. they run quiet. they don't move volumes of air, but enought to work for me.

One fan did not work. Other fan not much air flow. It was quiet though. When I tried them it was a couple days outside of the return window. Contacted seller and they sent a replacement set right away. Both worked.

My first order, both fans were DOA. Amazon replaced them, and that set is just fine. Also, while the fans were sealed in bags, there was no instructions, which at first seemed logical, not alot to replacing a fan, my intended use did not need the supplied connector and was going to cut the wires anyway. The replacement fans came with instructions and in them it tells how to take the wire connector apart to adapt to your system need. What is nice about these is you get the grills and mounting hardware. They are a very quiet fan and move a lot of air. This fans draw 120MA at 12 VDC, I am using 2 in series with a 33 ohm 1 watt, droppng resistor to run them off a 28V supply.

great service and item
