12V Ball

I gave it a 5 star but it is actually a little noisier than I anticipated. I am using it as a blower on a vintage Earth Stove fireplace insert and may order another to get more airflow.Shipping was as described, but tracking showed it was delayed from order time until shipped. No, I am not going to pay for Prime and patient enough to wait witch I had to do during our last snowstorm. Delayed by the PO, but will try it this weekend as we getting another blast of cold air. Overall, a value for the price, just don't expect too much. UPDATE: Small wires to motor break easily. I re-soldered connection and used hot glue to secure the wire to the body of the fan. Works great and no stress on the wires at the solder connection.

This is a nice fan and I like the speed controller. My only real complaint is that the red and black wires that connect to the fan itself, they are not well secured. The product photos show this as some kind of "take it all over the place and point it at random things" fan, but I think anyone who tries to do that will have probably broken the solder joints that attach the wiring to the motor within a week. So you really need to either mount this in a project where the wiring will be secured, do something to secure the wiring yourself, or just be very careful with it. The round exit port is glued in place, but not too heavily, and so it can be removed if you want to do that. The output is much more directional with the exit port in place. Without it, while the airflow is probably greater, it feels weaker since it isn't tightly focused.

This blower is perfect it has adjustable speed and works great as a Air booster for my wood stove

This little fan is powerful. But, if you want it to last, it needs to be mounted in some sort of enclosure. The power wires are soldered on, but the cable is otherwise loose.

Great fan. Good forceful air blast. I am using to cool hard-drives while cloning. The focused blast of air allows you to have the fan on a slower setting and limit the noise while accomplishing the needed task. I found another listing that included two fans on Amazon for $20 and purchased them as well. The cheaper fans seem to have similar output but they have more noise, parts are already separating, very short cords and don't include the grate. These appear to be "seconds" of the same fan. I will use them in the garage and for fire-starting in the wood stove.

Loud. Functional. Easy to plug in and operate. Moves more air than you’d expect

Yes, this thing is LOUD but it works great! I put this on my Lenovo SFF and it drops about 25°C ~ 35°C on K cpu. I did not want to modified my case, so, I try various different coolers and fans but they really did not work well - constantly, cpu temp. hits 100°C even on copper cooler w/ 120mm fan -. But this fan works! The only the problem is LOUD, very LOUD. If you are okay with it, it is great fan!

This fan puts out serious airflow; my use case is as a 3d printing remote cooling fan (CPAP) for a high-speed printer and it puts out more than enough static pressure and volumetric flow to keep up with crazy fast speeds. The built in controller works well for speed control and has a proper off setting where I measured no current draw. Overall noise was pretty good as well and much quieter and lower pitched than one of the 5015 fans found standard on many printers. The output is 1 inch inner diameter so if you are attaching a tube plan for a slightly oversized inner diameter or get a coupler.

Works as expected.

I bought 2 of these for my gas fireplace to help distribute the hot air. I like how you can adjust the speed of the fan so they aren't too loud. Works great

Works great

Bon produit même si ce n’était pas exactement ce que je cherchais.

Good air output .
