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..!!!

Smooth and vibration-free, the bearing and variable speed control are extremely helpful, great for providing that extra air movement when computer systems or amplifiers get hot. Great for upgrading systems as older fans wear out or fail.

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.

So far so good. I am used it for my of GE Side By Side Refrigerator compressor esternal cooling system. I took of the cover assess and replace my bigger fan with this small one and its working like a charm. Keeping my finger crossed, I bought another one to turn off one and turn on the other one every two days. You cannot get good service these days and the new fridge are too big in depth for my kitchen door.

This fan is bigger than I expected, even though I saw the dimensions before ordering. That said, it's working exactly as I hoped it would, cooling some computer equipment that tends to run warm by blowing some air across it. I chose this particular fan because of the controls, which are not part of the brick that plugs into the outlet and are fully adjustable from very low RMP to very high. The fan is quiet, but as you turn it higher (i.e. higher voltage/RPM), the fan does get louder. But that's the nature of the fan. This is basically the same type of fan you'd find in a computer, modified to connect to AC power, with two metal screens and some feet. It’s nothing pretty to look at, but functional. The main reason I'm only rating it 4 stars is that the brief instructions that were included are not relevant to this product, so essentially there are no instructions. It's not that I couldn't figure it out, but I'm an instruction guy and expect something basic.

Super fan. I use it in my closet to keep my modem, DVR, and ethernet switch cool.

i always buy wathai fans when i need small non PC air flow. I have 4x140mm fans and 2x120mm fans that direct my AC right to my face while i’m gaming. 2x140mm fans are set up with dryer vents tubes direct the exhaust from my pc directly outside my window. i have run these ran at almost twice their capacity for almost a year now using an after market speed controller and they still work great. you can tell they were build to take punishment

Bought this for a radio base station which has a tendency to run a tad warm on 45 watts output. Added the fan on top and it keeps cool air flowing through the vents of the radio and power supply. It takes a minute or two to add the upper and lower screen and the rubber feet. The speed control is a great addition to both change the speed of the fan up and down which ties into the fans noise. I run the fan at a little less than halfway (low noise) but turn it up for long transmission times (loudest). It appears to work great keeping the radio components cool. It does not move from its position sitting on the rubber feet on top of the radio cabinet. The radio is just beneath the top which is vented. The power supply has its own fan on the bottom of the cabinet. The radio is a Kenwood TK-8360hu-k and the cabinet is a Samlex SEC-1223-TK3 (23 amp) with a Kenwood KMC-35 IP55 microphone. I would buy this again for another radio. Note: on high speed, the fan noise isn't all that loud and it does provide a comfortable cool breeze around the cabinet as well.
