12V DC Brushless Blower Cooling Fan 50x50x15mm,for 3D Printer Humidifier Aromatherapy and Other Small Appliances Series Repair Replacement (12v Dual Ball Bearing 2pack)

Could it and last as long

Bought these while doing a major overhaul/upgrades to my Anet A8. Wanted something quieter than the stock blower but just as or more powerful and while it fits both of those needs I wish it was a little quieter but hey for the price and the fact that you get two I cannot complain too much. I still have one as a backup and the first one has been running great and although it is only a little quieter than stock it does not have the rattle sound that the stock one did.

After trying several different types of fans, I have found this style to work the best for moving air. The sound emitted is noticeable, but not distracting.

For years, I have been replacing the sleeve bearing blower in my humidifier. It lasts about a year, and it gets progressively noisier. I was amazed when I replaced my blower with one of these ball bearing models... it is VERY quiet. Plus, the ball bearing unit is rated to last twice as long as the sleeve bearing unit, and the ball bearing unit costs very little more. I'm sold!

I replaced my old 5015 fan as it was really noisy, but these are also noisy. Sounds like the fan blades are touching the side of the fan housing. Tried to adjust the mounting to make sure its not twisted etc. Still noisy.

The description says 5db, but it is more like 35 db. These are very loud. They move a decent amount of air. Even at half voltage they are above 25 db...

My Craftsman 20V system 1/2 drill came with a charger that has one of these fans in it to cool the heatsink inside. After several years, the original fan had a bad bushing or bearing and made lots of noise when the fan would activate. Other than having to buy some extended security bits to reach the screws to disassemble the charger to make the replacement, the new fan with bearings (according to the description), is working great. I did have to swap out the connector to the original one for a good connection fit.

Edit..These are failing now...Wow these are amazing! Very quiet. I use on my 3d printers and i have tested many. These are legit. Out of all I have tested I like these the best. Hopefully they last so as of now a 5 star
