12V DC Fan Strong Quiet 120x120x25mm 12cm Small Cooling Fan 2Pin 2Wire 1600RPM High-Performance PC Fans 120mm 2-Pack

These are used as the house battery cooling fans on an Airstream Atlas. The stock fans are noisy with an ear-splitting whine. These are far better but almost get 4 stars because they still are not as quiet as Noctua fans. The problem with Noctuas is they are either 3- or 4-wire and that's a sensor to turn them on or off. These are 2 wire like the stock fans. Replacement was simple: snap out the panel with the fans (it has clips), cut power (I pulled the fuse), open up the connectors to the power source and pull the fans' wires out. Unscrew the fans. Attach the new where the old were, using the same screws. Clip off the connector--you don't need it--and strip the wires back about 1/3". Insert the black wires into the connector with the black source wire, and the other two into the other connector. I'd restore power before closing the panel--air should be blowing the chamber, not out into the living space. If it's right, close it up and enjoy a quieter fan! I do have some extra Noctua isolators I'm going to try to see if they help even more.

Fans worked and were within specs.

I've seen several complain that the plug on this fan doesn't fit anything. Doesn't fit a motherboard plug, doesn't fit a Molex plug, etc. This fan makes a descent replacement for a ATX 12V V2.3/EPS 12V power supply internal cooling fan. I've used this fan when the power supply internal cooling fan either fails or becomes noisy. The plug inserts right into the socket on the board within the power supply. Be advised though that this is a quiet fan so it won't move as much air as the noisy fans.

This computer had a built-in 120x120x25mm fan. The fan that was built into it was a decent one but the bearing was starting to go. It was getting more and more noisy. I went looking for a replacement and wow the prices of Power Supplies for computers has really really gone up. Bought new it was $26. Now it would be $39 for a no-name and the really good ones like I had were $99. I measured the fan carefully and went looking for alternatives. This matched from the connector, to the size etc... There were some interesting differences that I did not see a measurement for. The power cable on the initial fan was about 5" long. The one on this fan is more like 12+ inches long. Not a problem just a different to call out. I got the old fan out and the new fan in in just a few minutes. It worked perfectly. So overall summary. The size is perfectly spot on. It is a 120x120 fan. The noise is extremely low. It is very quiet. The air flow seems a little lower than what was there before. It is hard for me to measure but it just "feels" a little lower. I am hopeful that it is enough air flow to do the job. I am pleased with the quietness, with the quick delivery, and with the fact the 1 of the two that I tried worked right out of the box. Super happy to have the computer back up and running so fast. Note: I will be watching the heat level. If things should prove to overheat because the air flow is too long I will update this review at that time.

Hooked up both fans to cool a marine Isotherm refrigerator. They are quiet and move plenty of air.

I haven't plugged them in yet, however I'm already well pleased with what was delivered. In the picture you can see, 2 fans (notice the 2 sets of wires with triple pin connectors). Note only 2 wires, but that's standard. 2 fans 2 fan fences (or whatever you call the wire covers) 8 screws for screwing into the plastic of the fans. The keyboard is just my own keyboard, not included of course. =) If there are issues, I'll post them here. I have a specific use for 1 of them in 2 days at a client's house. Should be a simple / routine swap out. (her fan is noticably slowing down and system is telling her to hit f2 because her system fan is failing) System fan in this case is the one on the rear of the (older) HP tower computer that blows heat out of the computer. (most platforms call this the system fan) One last note in case you're wondering -- measure in cm, multiply by 10 for mm. and when you measure measure the X and Y across your fan's case, NOT the fan itself, and NOT the distance between screw holes. So 90mm is 9cm X by Y, outside edges. It had been a while for me and I'd forgotten which way to measure when I went to order. If you think about it, there's little to no difference 92 vs 90mm. There's a bit of wiggle room with the screws screwing into plastic. So if someone is concerned about 92mm, just consider the extra mm will likely stretch easily in either direction. Measuring this is not like a monitor, where you measure the viewable screen diagonally (inside the bezels). Beware TV / monitor mfg's sometimes will cheat and measure outside of the bezel, diagonally.

Replaced the old single fan behind the refrigerator in our camper with two of these. The old one had started to make a whining noise. These run quietly and the refrigerator cools better.

They are fairly cheap… so… can’t complain too much. However, if you want higher quality, you’ll have to pay a higher price. They do what they advertised to do, but started having issues less than 6 months in. Grinding noises intermittently. Failed after 11 months. Granted, I had them going 24/7 on medium in an air conditioned, dry space. Your mileage may vary.

These fans feel more powerful at moving and pushing air per measure of noise than the stock fans on the ASIC I installed them on. Their noise is very regular and reasonable for the speed.

Bonne qualité pour le prix

I bought a brand new Dometic CFX3 35 refrigerated cooler for travelling and the condenser fan was defective. Stopped working 2 weeks after I purchased it. Fan over current which means the condenser fan was defective and burnt out. Dometic is known to be a nightmare dealing with defective products and who knows how long it would of taken to get this sorted out! I decided to fix it myself and ordered a 2 pack of these fans for $20 dollars. Fairly easy to replace although the connectors had to be changed to accommodate the new fan. It’s a tad louder than the original but works flawlessly and avoiding the Dometic nightmare was key! Been running for a month no issues. Just be sure to use the right size and max amp draw or close. Very happy with the purchase and not dealing with Dometic.

I’ve been using this 12V DC Fan (120x120x25mm) for almost 3 years continuously, and I’m genuinely impressed with its reliability and performance. I use it to cool my Rogers modem, which tends to overheat during the summer, and this fan has kept it running smoothly without interruption. The fan is surprisingly quiet, even after all this time, and it delivers strong, steady airflow. Despite running almost non-stop, it hasn’t lost power or made any unusual noise—truly a testament to its build quality and efficiency. If you’re looking for a durable, quiet, and effective cooling solution, this fan is an excellent choice. Highly recommended for electronics cooling or ventilation needs.

DIYキャンピングカーの換気扇用のファンに使用しています。 音は寝ていても気にならないくらい静かだと思います。 風量もそこそこあり満足です。
