621 customers mention561 positive60 negative

Customers are satisfied with the cooling capabilities of the fan. They mention that it significantly cools the devices they want to cool, and the CPU stays under 60C even under heavy loads. The fan moves a decent amount of air, and a two fan approach works quite nicely.

437 customers mention407 positive30 negative

Customers like the quality of the electronic component fan. They mention that it's well-made, sturdy, and quiet. The ball bearings should last a long while, and the rubber feet on both top and bottom of the fan make it very secure. It's a great buy at a good price, and it keeps their A/V receivers nice and cool.

"Xbox One is a fantastic gaming system, but man, does that little black box get hot! Especially after 12-16 hours in Fallout 4...." Read more

"...USB powered, I used a random Apple USB plug. Seems well made, works." Read more

"...has been a few years and it is still running strong, so it is a high quality product." Read more

260 customers mention181 positive79 negative

Customers are mixed about the air flow of the electronic component fan. Some mention that it's very quiet and moves enough air to keep all devices at what feels like a cool temperature, while others say that they don't blow much air and airflow performance suffers. That said, some say that the fan is not strong enough to blow smoke.

"...at ~75C. With the MULTIFAN S3 in place, peaks hit 65C. Excellent for low-RPM, purely external cooling!..." Read more

"...There is a subtle movement of air as well, not a breeze; simply lick the back of your hand and hold it 2 feet away and you will notice the cooling..." Read more

"...XB1 has a large internal fan, but it's lethargic: it draws a small volume of fresh air and pushes out an equally small volume of hot air out the top..." Read more

"Very quiet, moves good amount of air, USB makes power easy. Very Pleased!" Read more

185 customers mention150 positive35 negative

Customers like the speed of the electronic component fan. They say that it has a speed switch, and they appreciate the option to change fan speed. They also like that the speed controller is a hardware switch, which means that it will work after power loss. Customers also appreciate the handy on/off switch and the ability to daisy chain additional units without using it.

"...So far, I am happy with this newer model fan. The variable speed switch is nice, shame they took out the USB-to-AC power adapter, but that's OK, I..." Read more

"...The newest AC Infinity now has a variable speed switch, and costs less. Cabinet temps seldom exceed 5-7 degrees over the ambient room temp...." Read more

"...The speed control is nice, however I have mine on high at all times. Plug into an empty USB slot and it fires right up...." Read more

"...I really like that the speed controller is a hardware switch which means that after power loss it will come back on at the same setting that was..." Read more

137 customers mention137 positive0 negative

Customers are satisfied with the value of the electronic component fan. They mention that it is a good value as long as it lasts a few years.

"...My solution is simple and relatively inexpensive (especially considering the cost of a new XB1). It's also two-pronged:PART ONE: This fan...." Read more

"...The 120mm seems to be the best fan for the money.Original review:Small, but not so small that it can't move air.QUIET!..." Read more

"...AI-MPF120A had some excellent reviews on Amazon, and given the reasonable price, I decided to give it a try...." Read more

"...Given all of the great features, and its very reasonable price, I could not be happier with it...." Read more

130 customers mention125 positive5 negative

Customers like the usb connectivity of the electronic component fan. They mention that it is powered from a USB port, so they do not have to worry about any additional cords. The fan, speed controller, and USB plug are all USB-powered. The large fan size, USB port power, and variable speed features, make it a good fit for most systems. The on-off switch and extra USB plug make it easy to use both locations. The AC to USB adapter and grilles for both sides are also included. The pass-through female USB is a great idea.

"...It's a good fit and utilizes the side USB port (I didn't even know it was there)...." Read more

"...adjustment switch, had vibration dampening feet or pads, and was USB-powered...." Read more

"Sits wherever you put it, no installation required. USB powered, I used a random Apple USB plug. Seems well made, works." Read more

"...The fan is powered by USB, but it also includes a USB charger / power supply, so it can be wall-powered as well...." Read more

Great quiet fan for cooling audio/video equipment
5 Stars
Great quiet fan for cooling audio/video equipment
After spending almost $500 for a good quality audio/video receiver for my home theater system, I was kind of disappointed at how hot it runs. It sits in a semi-ventilated A/V table and gets almost scorching hot to the touch and you can almost smell the electronics burning. I thought I would try a fan to put on top to help cool it and selected this product and I could not be happier. I plugged it into a USB port on the TV that is only powered when all of the A/V equipment is on. It is whisper quiet and it is amazing how much of a difference in surface temperature this fan makes on the receiver even though I only have it set on the medium speed. It has been a few years and it is still running strong, so it is a high quality product.

Ho preso questo ventilatore per la mia collezione di Nepenthes. La cosa più sorprendente è la silenziositá, anche quando è impostato al massimo. A livello di potenza non è molto forte, quindi non adatto a spazi grandi, ma per una piccola serretta o terrario è perfetto. Consigliatissimo!
