This fan is perfect for venting an entertainment center or a computer desk because it is powered by a USB connector and it has a speed control allowing you to adjust the speed of the fan for the best combination of airflow and (lack of) noise. The wires leading to it stay out of the way because they are on a spring-loaded reel which takes up the slack. I purchased a new entertainment center which, hard to believe, has no power outlets or vent fans! The area where the equipment resides quickly became an oven. For the first few weeks I had to leave the doors open all of the time, a completely unsatisfactory situation. I wanted to install fans to vent the cabinet, but powering them was an issue. This fan solves the problem as it is powered by the USB port on the back of one of my TiVos. I also installed one in my wife's computer desk, which made it run 20+ degrees cooler and much quieter. In both cases, I removed the "legs" and purchased longer bolts and nuts, drilled a hole in the back and mounted the fan. It took about 5 minutes for the installation. Highly recommended!

Although iMacs are designed to handle the heat generated using "passive" cooling (read no internal fan) I always use the philosophy that cooler is better. I mounted this fan behind my iMac and use an already existing hub to plug it in. It's quiet and the computer runs noticeably cooler. Will it increase the life of the computer? I don't know. But like I said, cooler is better. I do wish there was a power switch incorporated into the speed control but unplugging it isn't really much of a problem. I'm totally satisfied with the unit.

I recently lucked out and got my hands on an Atlantic Technology FS-7.0-GLB 7-channel surround bar (Gloss Black), and purchased an Onkyo TX-SR508 7.1-Channel Home Theater Receiver (Black) to go with it. Having read the reviews on my receiver, I was forewarned that it runs very hot, so I began my search for something that would keep it cool, but not break my bank. I couldn't have asked for better than this USB-powered cooling fan.

After initially setting everything up, I thought that the best place for this fan might be at the rear of the receiver, over the hole through which all of my wires and cables passed to and from my receiver. Uhm, yeah NOTHING was going to be powerful enough to suck the heat from the receiver with it set THERE! So, once I'd figured out that I needed to lay my ThermalTake fan over the TOP of the upper grate on my receiver, with the fan speed knob (obviously!) facing up, I unscrewed the little wire "stand" that it's on, put it in place, and it's done the job SPECTACULARLY! Before, my Onkyo receiver would literally get hot to the touch after a few hours of operation. Now that I have my ThermalTake fan laid over top of it, it actually stays almost cold to the touch, even when it's on all day long.

There are plenty of other cooling options that one can find online and in-store that are billed specifically as cooling options for A/V equipment, but you really can't possibly go wrong with this awesome little USB-powered fan. The RPMs of this fan exceed what I came across on a website for another fan billed for use with audio receivers, and that fan was being sold for nearly double the price of this one, before shipping. All it took was for me to move this to the right place on my receiver for this fan to get it super cool.

Amazon continues to amaze me with the bargains that I find here. Of course, without the helpful reviews that other users put up here, I wouldn't have had a clue what to buy or how well it'd work. Thankfully, the other folks that've bought this fan led me down the right path, and I have every confidence that I'll be able to enjoy many, many years of great sound from my audio receiver, so thanks!

The product is based around an 80mm computer case fan, with a wire stand and a rheostat to control the fan speed. The retractable power cord extends to over 50" which is more than enough for me. Besides being useful for cooling notebook computers, this is also helpful for cooling off stereo components and related electronic equipment since heat is the enemy. At higher speeds, the fan does make some noise however.

If you are looking around for usb cooling fans on Amazon you might have noticed that is there another Thermaltake fan called the Thermaltake Mobile Fan II External USB Cooling Fan. Let me note that this one (Thermaltake Mobile Fan 12 External USB Cooling Fan) is larger than the other one (Thermaltake Mobile Fan II External USB Cooling Fan). Looking for a space saving cooling solution I decided to buy the smaller one instead. Upon arrival I tried using it only to find what a few other reviews pointed out in that the wiring for the speed control is faulty. The fan controller doesn't allow the fan to reach 1/4 of the highest speed of the fan without stuttering. The stuttering is so bad that the fan blade almost comes to a halt. Disappointed by the faulty fan I returned it for this larger model. Upon receiving it I immediately plugged it in and messed with the speed control knob to see what it would do. Needless to say it worked like it should. The fan can achieve the fastest or slowest speed it's capable of without any stuttering like the smaller one. I am much happier with this fan as it moves more air (or the same amount of air without the noise of the smaller one) and the wiring for the speed control isn't faulty either. Great fan that I'd highly recommend!
