Firstly, the radiator is far from `leise`entfernt that two fans are yet to hear very high frequency and loud.
operates one of the cooler with 5 instead of 12 V, so runs on only one of the fans.
Even at 12V it lowers the temperature of the Rams only about 2 °. To illuminate the cases and to hide as the 24-pin ATX strand quite nice, useless as cooling for the Ram.
