Dorhea Fan 60x60x10 mm DC 12V 6010 Brushless Cooling Fan, Replacement Ball Bearing 60mm Fan for Cooling DIY PC Computer Case Fan - 2 Pin Case Fan (Pack of 4Pcs)

I use these for non-computer uses (airflow through insect enclosures for anti-mold purposes) so I can't say how they work in that setting, but they haven't failed me yet! Perfect size for what I need an they emit a very low amount of noise. So far the quality is up to my standards and I will be buying more soon!

Updated Review: The issue I had with these fans appearing to have been 5V fans labeled as 12V has been resolved. In the last 5 packages ordered, all fans spin at the correct speed and draw the correct current. Good product at a great price. Original Review: I used the 12V versions of these regularly for a product I manufacture. They WERE great. Good price, good air movement and quiet. Then I got a batch that drew twice as any milliamps, spun so much faster and made so much more noise. I can only guess they're mislabeled 5 Volt versions of the fan. Happened with two different orders.

Great quality, and the size is good. It is important that for me at least the fan moved slower then I expected, but it was still very quiet and efficient.

Worked perfectly for a outdoor DIY project.

Seems like a good value even though one of the four was inoperative at delivery

Very quiet

Very good fit. S-360-12

Disappointed in this item. Met all the specs and purchased these to replace four fans in external computer RAID enclosures. After installation the fans wouldn't even start so, be warned if you are using these for something that needs critical cooling such as hard disk drives in RAID enclosures. Glad I checked to make sure they were spinning. Noticed they did have quite a bit of drag when manually spinning them. Had to spin them manually to get them started. The RAID enclosures allowed for three speeds (low, medium, and high) and had to leave them on high for them to keep running without stuttering. Hope they loosen up a bit after operating for a while. On high speed they were noisy, more then the previous fans of like type. Finally, not necessarily a ding for these fans, the connector didn't match those on the old fans. Not a problem for a tech with soldering skills and gear to swap them so don't throw the old ones away until your sure their right for your application. Looking for a second set of fans at this point.

Well greased little fans move a good amount of air good for tiny computer builds.

Poor quality fans, worked good first day of use. Real loud second day until the fans warmed up, third day 2 of 4 fans need help starting. Took two hours to install into my monitor and now I have to do it all over again.

These were not bearing fans.
