DISH Network recently replaced our DVR with the 722 Duo model. Some online research told us it's a model plagued with problems that all seem to originate with the box overheating. We figured we'd be proactive, and looked into cooling fans; a little research led us to these AC Infinity fans, and we're glad we got them. We placed one on each side of the DVR vent holes - right side draws air in, left side blows it out. Since setting these fans up a couple weeks ago, our DVR isn't even warm to the touch. Even on the highest speed, you cannot hear them run - they just sit there and quietly do their job. Should we need more of this type fan in the future for other equipment, we will definitely be return customers. Very happy with our purchase!

I bought these dual fans to sit atop the vents on my Oppo 105D since it sits in a cabin. So easy to set up. Simply plug into one of the rear USB ports and put them in place. Whenever power to the 105D is switched on, the fans start right up. The fan speed is adjustable to fit your own setup and fan noise preference. A+ product.

I bought these 80mm fans to cool a Roland V-1HD video switcher which has a notoriously loud fan. When in my studio I this product to be MUCH quieter than it is. I have taken the lid off of the switcher and unplugged its fan, and then set these two fans on top of the logic part of the switcher. The rubber gaskets make them barely rest on the edge of the enclosure. I couldn’t have hoped for quieter fans. I’m very happy with the result!

My home stereo receiver used to get very hot after around a half hour of being on, whether playing music or sitting with the power on. I bought these fans and it has made an immediate impact on the temperature. My stereo is running so much cooler that I am not concerned about it overheating anymore. I would highly recommend this product.

Theses fans are a great addition. I use them where ever I happen to be sitting just to quietly move the air around me. Living in a 45' RV means you only keep things that do the Job they were designed for and don't waste space. I also have them on my wifi router and Xbox. Before I got them I was always worried about overheating, but no more. Thanks for a rock solid product that works as described. Thanks
