2pcs Cooling Blower Fan DC 12V 50x50x15mm 5015 Fans for 3D Printer Humidifier Aromatherapy and Other Small Appliances Series Repair Replacement

I ordered these blowers specifically because they were advertised as having a 0.23A draw (2.76w) as opposed to the standard 50mm blower drawing 0.15A (1.8w). In this case air moved is almost directly proportional to power consumed. I was specifically after the high airflow and air pressure that higher than normal power would provide.These fans DO NOT run at .26A, rather 0.06-0.09A depending on load. That's quite the difference and for my application totally useless.Additionally (pictured) if you scrape off the specs that they blacked out you'll find that they are actually labeled at 12V 0.06A.On the upside I guess they are pretty quiet, if that's what your after but I can not condone any company falsifying specs, for any reason, ever.

I bought these to repair a broken fan in a humidifier. Items shipped quickly and arrived in great condition.Both fans "worked", but one of the fans has something wrong with it - it sounded like a buzz-saw. For a humidifier in the bedroom, this was the difference between sleeping and not sleeping - it was just that loud.I swapped the fans. Testing with a sound app on my phones, the difference was roughly 10db - not insignificant.I sent an email to the seller through Amazon - I received a faulty product and wanted a replacement, but as one of the two items were in use, I was hoping to arrange for a partial replacement. I waited a week and never heard anything.Overall, I am happy with the one that works. Since the original fan lasted less than two years I figured I had a replacement and a backup. Clearly that isn't the case.If the seller wants to fix this, I am happy to adjust my review.If you're looking to buy this product, when it works, it works great, but as of now, I can't recommend either the product or the seller because my experience has not been great.

The blower replacement was correct... size and operation were OK. However, the first of the two units had the wires reversed, so the blower did not operate as delivered. I needed to reverse the red and black wires on the plug to get it to run. I haven't yet examined the second unit.

Absolute trash,The fan spins but so slowly it is barely pushing air. I can blow air harder just by softly exhaling. I wasn't even certain they were on until I directly powered them to watch the actual blades spin. I thought it might be a bad fan, but both are equally weak. If I could give 0 stars I would, the only possible reason for 1 star is that they are silent. If they made any noise at all, the audible vibrations might actually move air better than the fan blades do.Honestly, this was a complete waste of money.

The two fans looked and fit exactly like the blower fan that had been in our Homedics humidifier. The problem was, the first fan I installed barely pushed any air at all. I threw that one away and the second one actually worked and blows the same amount of air as the original Homedics blower fan. I saw from other reviews that others have had similar problems. The manufacturer has to do a better job.

I mounted them on the side of my work bench to blow the solder smoke out of my face. Powered with a recycled 12V adaptor. They work great. Draws air from one side, which you therefore can't cover. They make a whining noise, which is tolerable. I'll put them in a sound absorbing box some day.Product arrived promptly.

Fans worked for a few days of moderate use on my 3d printer. They still spin but make a loud chattering noise. I'm not sure if it affects the fan's blowing strength but it seems like the blade might be coming apart from the motor.

I bought a pair of these for a humidifier even after reading the bad reviews, thinking I had better odds if I got two. Both junk. Found the problem: MADE IN CHINAAfter my first return I ordered 2 more that were also defective. I just want to repair my 3 month old humidifier that failed.
