Premium Fan

Even at the packaging you can see the good workmanship. This can also be felt at the relatively high weight of the fan when removing. The contents of a 7V adapter via Molex addition is still in the process.

The installation is quite simple, you do not even need a screwdriver. However, I do not know if it elicits the mounting pins also readily again.

This fan is practically inaudible. Since it is decoupled from the housing by rubber studs, also vibrates doing nothing. Interestingly, I can change the speed by Speedfan, although this was supposed to be fixed.
The air flow rate is entsprechendend low speed rather low.

From me there is a strong buy recommendation, although I rather the PWM or the Middle-speed version would buy me, because of the greater air throughput.
