GDSTIME 40x40x20mm 12V DC Axial Cooling Fan 3-Pin

these are nice little 3 pin fans. I got them for a SFF build but unfortunately they didn't fit, however I have tested them because I will eventually find a project for them. For a small SFF case, these actually move a decent amount of air considering that they are not pwm and they just have 1 speed they are almost whisper quiet. For the amount of heat generated by my little system these would have been exceptional for removing that heat and encouraging airflow. They feel well balanced too, I didn't notice any abnormal vibration in them when running so that bodes well for longevity of the bearing. They were also pretty cheap so this is a win.

Works great, but I feel there is a typo in the description. Although mine are turning 7k+ rpm, it says 60k which I think should be 6k. Expected noise level from a fan this size and speed range.

I needed a very slim fan for my Hyte Revolt 3 top fan. This one works great it has a strong and quiet motor. It really pulls the hot air out well. The quality is typical for a fan. It comes with a grill, and installation is pretty easy; you can plug it into a 4pin cable. I consider this a great upgrade at a very minimal cost worth every dollar.

These are very thin fans, worked well and quiet.

Works well, decent quality

These fans are not quiet, and have no rubber vibration dampening. Overall, a bad buy and I replaced with something better.

Great airflow. The description didn’t say it came with nuts and bolts, so that was a pleasant surprise that saved me a trip. I have them running at full speed, and the noise is minimal; there’s a quiet hum, but I’m using it for a 3D printer, which is louder, so it’s not really a problem. If you want a completely silent fan, you’re gonna have to pay a little more.

Nice and quiet and work great
