I had an 8 cm fan of the brand in my PC (rear) and had from the installation to stop working no problem. Since my PC is in the computer cabinet, there were temperature problems especially in extreme games. That's why I have 2 pieces of above 14cm fan ordered and installed at the top of my PC case. (Holes or fastening points were available). The temperature problems are solved and since the fans are not heard during normal operation. Even if the speed of the fan is the limit in ultra-games, the noise is acceptable. So thoroughly recommended.
