I've got a kegerator, and the best way to keep your beer from foaming (and to get a really cold pour) is to blow cold air into the faucet tower. All of the how-to's on the internet say to use a computer fan and build a housing. This fan is a couple of magnitudes better, absolutely the best, it has the power to really push some air. Highly recommended.

I ordered this on a whim, as part of a larger order. It was cheap, so I said why not. I use it almost every day now to cool my face! I hooked it to my power supply and whenever I get warm, I turn it on and feel the beautiful breeze of awesomeness. It's quite loud, but if desired you can reduce the voltage (it's not a PWM fan). At around 8.5-9.5VDC it is quiet enough for me while still being good at cooling. For people that need a strong burst of directed air, look no further. Only thing missing from this fan is a grill on the intake (wouldn't want to trap my finger in there as it spins). Quite loud, very powerful air pressure (16CFM is a lot coming out of a 33mm diameter hole). Recommended!

I purchased this blower fan to provide air-cooling for my kegerator setup. I have a fridge in my garage, and taps in my bar, with about 7ft of otherwise unconditioned lines between the two. I used this fan to blow to cool air through a 1" flexible bilge pump hose to the top of the tower, and had the return air travel between the outside of that hose and the inside of a 2.5" flexible vacuum hose back to the fridge (this space is also where the beer lines are routed).

I previously purchased a 12CFM blower fan off amazon which pulled 0.3A @ 12VDC (for the same price incl shipping), and the temperature at the top of the tower was a mere 62degF. After replacing with this fan, the entire (insulated) tower sweats like a cold glass of water on a hot day. I actually reduced the voltage to around 10VDC because it was more than I needed.

If my other blower is a true 12CFM, this is probably more like 36CFM. Given their similar plastic squirrel-cage design I can assume they have similar efficiency, and so this one which draws 3x the current probably moves 3x the air.

Its plastic design may not be durable enough for extreme uses, but I think in most applications this will stand up very well. BUY IT!

I've had this running 24/7 for about a year at 12v. Nice air flow and with a screen over it and good air quality this thing has been a champ. However even with a vibration dampener and keeping it completely clean it is still a bit louder than I would like. I either need a bigger living room or a quieter fan, the latter being cheaper.

We bought four of these to inflate a couple of Halloween costumes. Two were not powerful enough to keep a costume made from parachute ripstop nylon that measured about 7.5 cubic feet inflated. We tested the costumes with a shop vac, and they inflated just fine, so we thought that 16 cfm would be enough for mobile use. Sadly, not sure they put out that much air.

We will most likely use these for other projects.

Bought 2, 2 arrived one smashed and the other not working. Poorly packed in a box with no packaging to stop it moving around. No real surprise that 2 plastic items in an empty box were smashed.

What a joke...

Moves a considerable amount of air for its size. Not sure how long they last, but for the price, they're a good value.

Static pressure was weaker than expected. Bought some of these for use on a 3D printer with cooling shrouds. Airflow through the shrouds was far less than through tubing.

Fit exactly and runs better than the original

Hooked it to some pic pipe to make a boxing glove dryer and it works awesome!

Not enough static pressure for my purpose. Intended to use this with a blowpipe torch for jewelry making.

Search continues.

For now I just use my lungs.

I bought 2 of these. They both showed up broken.

They quickly sent 2 more. One of the 2 was broken.

Returning them all. If they show up broke, how long will they last under use?

The clips on the case are all broken, preventing it from holding together. The fan on the inside was broken away from the enclosure and it doesn't look like glue would hold it in place when in use. And, when applying power the fan doesn't turn on at all.

Looks like others have commented about also receiving defective products. Won't be ordering this thing again!

Both the black and red wires just fell off unexpectedly. Worst soldering job I've ever seen. I'm willing to bet poor soldering is the reason it didn't work for some of the other reviewers. It seems to work fine after reattaching the wires.

Every holiday we put airblown decorations in our yard. For Christmas we put 60+ out for the town people to bring their children and grandchildren to see. We get hundreds of little visitors. These fans are a great replacement for the fans in the decorations. The have the cfm to keep them well inflated.

This baby helped us win the Startup Week Pinewood Derby!!

(admittedly we ran this at 20v for some extra oomph...though that was informally condoned by one founder of SparkFun)

Great airflow and fairly quiet.

I ordered 2 of these blower fans. One worked and the other one didn't. The one that works does what i need it to do just fine. I guess cheapo's are hit or miss, but for the price, if you get one that works, you've made a great little deal!!! Good luck :)

I have purchased eight so far and used four of them. I have had no problems with them so far. They are a little too noisy for my main application running on 12 Volts, but are great @ 6 Volts. Since I primarily use 12 volt batteries, I am looking for an affordable way to vary the voltage on them.

It is a fairly strong blower and I'd agree with the SF description that it does seem like more that 16cfm. It is however almost 100% plastic and of "snap together" construction. And it is somewhat noisy (as in vibration). Nevertheless for $5 you just can't go wrong!!!!

So I'm trying to make something to suck up solder fumes in an attempt to avoid lead poisoning or something. So I thought this would be a good fan for that; just run power into it backwards and it'll spin the other way and suck instead of blow. Well not quite. Long story short, I opened the thing up and poked around a bit. Looks like it's a brushless type motor, so it won't spin backwards. And if you put power into it wrong for very long, something releases it's magic smoke. HOWEVER the fan still works! When powered the right way of course. I haven't used it for very long seeing as it's not what I needed for my current project, but this fan moves a lot of air!
