## Customer Reviews

### ⭐⭐⭐⭐⭐ Good replacement for CR-10S Pro V2 case fans
*by W***L on March 5, 2024*

The blower fan in the case of my CR-10S Pro V2 was starting to die after all these years and made a terrible grinding noise. It is the same fan as the part cooling blower except for the end connection. There is a clip on the hotend blower and not on the case fan. I bought this to fix that issue. It runs quieter than the previous fan with a small decrease in airflow. I definitely recommend it as a replacement for the case fans.

### ⭐⭐⭐⭐⭐ These move a lot of air
*by L***R on February 6, 2022*

This blows significantly more air than the 4015's I usually use. They have a smaller footprint overall but a larger opening and move a LOT of air. They're noisy at 100% speed but if you need to cool something, this is the fan to use.

### ⭐⭐⭐⭐ The power cable is too short, but they have a strain relief.
*by D***N on December 13, 2024*

I had to replace the part cooling fan on my CR 10S Pro because the Creality fan solder joint failed. I purchased these fans and designed a shroud to fit on a Bond Tech DDX extruder (photos included). There is a connector on the end of the cable, but not long enough to go to the breakout board. Therefore, I had to splice the wire. I would have preferred just mounting and plugging in (4 stars)
