2PCS Blower Cooling Fan 120x25mm 110V 220V AC Powered Cooling Fan Dual-Ball Bearings 3 to 12V Speed Controller Fan for Receiver DVR Compatible with PlayStation Xbox Component

I bought these through AMZN and use them to cool stereo equipment contained in a cabinet. They do the job, they are quiet and run 24/7 with no issues. Recommended.

I purchased these to place on top of my Mac Pro 6,1 computers (have two) to help the factory fan extract heat.They work good (I drew up and 3d printed an adaptor) but are louder than the factory fans.They will get the job done which is the important purpose.

When I build small to medium size wooden projects I almost always paint them or put a varnish finish on the wood. Positioning one of these fans to push air across the surfaces speeds up the drying and curing of the paint.I've also used these and smaller ones blowing 24/7 on the bottom of my windows that will get condensate or frost at the bottoms when outside temperatures drop to zero. It prevents humidity from condensing on the glass and thereby protects my window frame finish from getting drips and ruining the finish. These fans run quietly for 5-6 months every winter for 7 or 8 years now and have not failed yet. Worth the money. And they only use a couple pennies of electricity in a month.

These are not high-volume and are kind of weak, super quiet, but were perfect for my application when turned on max speed. I can't imagine what the lowest speed could be used for, perhaps blow-drying silica fume without actually moving it? I also easily broke a blade off a fan, by holding it to tightly while pressing it into place for installation. But, there were two, so NP

Finally an adjustable fan! It has a great range of speed and can put out a lot or a little bit of air. It doesn’t make noise even when flat, upright, or tilted. I’m using it to circulate the air around my plant growing shelves. I tried the clip on fans that I thought would be better suited for the task but they all made noise. These computer fans are so much better and so quiet! I’m very happy!It’s worth noting the while the front of the fan has an incorporated plastic guard, the back doesn’t.

Product arrived non-functional. Requested return immediately.

These were purchased for a private art project that was not a typical use and they’re beautifully quiet and plug and play friendly! I love the safety features of this fan and it’s simplicity for working so well, now we’ll see how it does long-term. I will update you as possible.

The product works fine, but I got one that has a broken or not connected wire, so it currently doesn't work. I don't want to ship both back as I need one right now. Hopefully the seller will see this and make it all good.
