120mm x 25mm AC Powered Computer Fan with AC Plug 110V 120V 220V 240V Variable Speed Controller 3V to 12V, for Biltong Box Greenhouse Receiver Amplifier Xbox DVR PlayStation Component Cooling

I'm a big fan of this small, 120mm fan. I use it to exhaust fumes from my 3D printer enclosure and it works flawlessly all day. Provides a ton of air flow for the size, is pretty quiet, and I love the adjustable power setting. Would recommend.

Bought these for a pantry project to get airflow to my veggies so they last longer. Quiet fans and they move a decent amount of air. Also you can adjust the speed which is awesome.

I have a vintage Technics SA-818 receiver from 1981. It's in Mint condition. It's been in a stereo cabinet for many years, and it gets warm,and if left on for an hour or more, hot. I recently decided to install a AC Infinity AC-ACT10 fan ventilation system, for $129.00 . Yes, this was am expensive cooling system, but, with its build and features, I felt it was well worth it. I got the ACT -10 on Monday, and installed it immediately. When I powered the unit up, it ran Great..! However, the EMI/ RF it created,shut off ALL reception to the FM tuner..! I contacted customer service, at AC- Infinity and they suggested a ferrite core bead, on the AC power line would eliminate the noise....WRONG.! It did nothing..! I returned the unit, the next day, but was still needing cooling for my receiver. I looked at this fan, and read many reviews, from others saying this fan worked excellently with their receivers. I thought for $14 I couldn't go wrong. I installed it as soon as it came today, and tried it with my receiver. The fan on the lowest setting, moves tons of air..! And, absolutely no noise on the FM tuner side..!! Sometimes, cheaper IS better..!! I highly recommend this product..!!!

We actually bought this to push heat from our pellet stove down to our bedroom. Works very well in getting it there. No more cold nights.

These may seem expensive for ONE FAN at $14 - $20, but they aren't since most PC CASE fans don't meet this rated speed, don't have waterproofing, and don't come with the controller. My REATAN PC is all metal, and uses that fact to its advantage. The REATAN also has a fan on its underside to cool the RAM and M.2s. I use the 140 on the bottom to assist the bottom fan and suck heat from it. Then on top bought 3 40x120 heatsinks (going to replace it with a 120x120 that just came in) and used a 120MM WATHAI fan on top to assist with top cooling. Since the CPU heat spreader touches the metal top of this PC CASE. Keeps my CPU and GPU in the mid 40s. These things move AIR, you put your hand on the intake side, and it sucks your hand in, yay safety grills. Also these are REASONABLY PRICED, as someone who did try to jerry rig his own solution. Similar CFM rated fans cost about $15 minimum and top out at usually 1800RPMs. That's just the fan, add a filter, that's about $6 for 1 or can get a 3 pack for $12, then you need feet, $5 for 20, then the adapter to wall which is $5, then you need screws for the feet which are about $3, then you might want to control the fan speed so need a $20 piece that seems to only be made by NOCTUA. And there you go, when all is said and done, your homemade equivalent now cost you 3x as much. Especially if you want the same IP67 rating these offer. They're built well, move a crap ton of air, aren't loud, and are the complete package. ONLY ADDITIONAL PURCHASE I'd make, is a "Y" splitter that way you only need one controller for both fans in my setup, and is only taking one outlet space. That's probably the ONLY COMPLAINT I have, the control box is unnecessarily MASSIVE. Especially when used in the usecases they're describing. The noctua controller and CoolerGuy 12v to fan adapter is such a tiny package, you could easily VHB mount it to the front of your router, DVR, etc device. 100% recommend.

Neat little fan I use it for an extra exhaust fan for my kitchen other than my hood fan.

WORKS GREAT,, I USE IT TO COOL MY AV RECEIVER,, IT IS REALLY QUIET,,DOES NOT CREATE ANY HUM OR ANY PROBLEM WITH RECEIVER

Used this for my fish tank enclosure. Reef tanks have a lot of humidity from the lights and water flow etc. Instead of having the humidity trapped in the enclosure and potentially cause mold. I used this to exhaust it out of the tank closet and out to the roof exhaust . The dimming switch is cool. Non summer days I turn it down so it's not as noisy. But it's almost silent with the tank closed. I also don't need as much air moved during the winter.
