Cheap AC Infinity AI-CFD120BA Dual 120 Quiet Cabinet Fan Kit, for Home

Customer Ratings:

Our media cabinet is small, but jammed with equipment (TiVo, BluRay player, UPS, two iOmega ix2-200 NAS, and a gigabit switch) that generate a lot of heat. The temperature within ranged from 100-120oF (yes, that hot!). The ix2-200 internal fans, which kick in at temperatures over 59oC, were constantly running at 1000-1500 rpm, and they reported an internal temperature of 60-65oC. The only ventilation in the cabinet was two 3-inch cutouts for cables near the bottom of the back panel not very good to remove hot air passively.

It may be coincidental, but about a month ago, our year-old TiVo had a drive failure. After replacing the TiVo drive, I decided to actively cool the cabinet with dual intake fans (near the bottom of the back panel) and one exhaust fan (top of the back panel).

The reviews for the AC Infinity fans were excellent, so I purchased a dual AC Infinity 120 mm quiet fans for the intake (this product), and a single AC Infinity 120 mm quiet fan for the exhaust. The fans were very simple to install (and look good after installation). The cutout mask provided made it easy to mark the back panel and a I used a dremel to make the cuts. Because our media cabinet is up against a well, I need to remove the fans from the inside to clean the filters. Therefore, rather than use the provided nuts and bolts to mount the fan, I used industrial strength velcro. I tried using nylon push rivets, but couldn't find ones in the right size that popped out relatively easily.

The fans are very quiet. There is no speed control on them, but the specifications state they run at 1200 rpm. As provided by AC Infinity, the fans are configured to serve as intakes, but it is easy to reverse the direction of airflow need to remove 8 nut/bolts. Note that cable length will make it difficult to configure one fan as intake and one fan as exhaust for the dual 120 mm cabinet fan.

After one day, the fans seem to be working the temperature in the cabinet is around 80oF. Hopefully, they will last .....

Following a home theatre system redesign, space became a premium and in the case of the amplifier, I was concerned about the lack of breathing room even though I created some vent holes in the shelf above.

Subsequent temperature measurements indicated 100+ degrees F which is significantly higher than the optimal ~ 85 degrees F. At that point I started my search and came across the AC-Infinity family of rack coolers. Even though I wasn¡¦t using a rack, I am pretty good at ad hoc mods.:)

I elected the small 2 fan configuration (dual 80) as the most optimal for my application. I rigged the unit with a few wire ties and a push tack on the back of the shelf situate above the amp. Plugged it into the switched amp outout and the results were better than I anticipated. The unit now runs at ambient temperature even after hours of typical use. I cannot hear the fans even when nothing is playing.

Service: 3 days from order to install. Are you kidding me!

My small but cramped cabinet where I placed a TiVo, VCR, BluRay, Cable Tuner was not built with any ventilation by the installer. As a result, inside of the cabinet was always hot, like over 100 degree F kind of hot. I tried placing a small A/C fan inside but because there is no air exchange to the outside, it was just circulating hot air inside. After a few months, even the small fan seized and would stop working. After 2 of the fans seized up, it was time to see about getting ventilation to the outside.

Basically, the AC infinity fans are nothing more than computer case fans running 12V, screwed into a big hole that you will have to cut up. The beauty of this, however is with the top metal plate, which is beautifully finished and will cover up that unsightly big hole you cut up and the AC to 12V adaptor supplied. When and if the fans crap out, they are easily replaced by ordering perspective sized computer fans from places like Amazon or Newegg. Yes, I figure I can buy the fans and make my own AC adaptor and save a few bucks, but then there is no way I can make the metal plate and have the whole thing look as pretty as AC Infinity makes it.

People comment on the noise. Well, the best way to see how loud this thing is is just go and sit next to your desktop computer. Most desktops have a fan in the power supply and 1-2 case fans. This is about as loud as an average desktop computer running without the HD spinning. I am happy with this and yes, between the 2 fans and a big hole I cut, now my electronics are pretty much as cool as can be being plugged in.

Honest reviews on AC Infinity AI-CFD120BA Dual 120 Quiet Cabinet Fan Kit, for Home

I bought two for my Tv stand to cover both sides. The electronics inside would get very hot even with unit doors wide open. The hardest part of installing was simply cutting out the rectangles on the back of the unit. The usb tethering between the fans is a very nice touch. Both came with an outlet adapter however I'm currently using the usb port on my Tv to power both sets. This is a must have for those who have a good amount of electronics that are enclosed in any cabinet or wall unit.

Pulls a pretty good amount of cooling air through my audio cabinet. Not super quiet--your can definitely hear it if you are listening for it--but quite a bit more quiet than the previous fan I had in the cabinet. I have five components in the cabinet and they get hot without a fan. Definitely recommend that you get the double fan, as half the airflow from the single fan just would not have been enough to cool the cabinet.
