The installation of the cooler kits in the Dreambox 8000 is not without problems, especially if a 3.5-inch hard drive is built with. Left corner of the fan at one of the hard drive mounting screws, right there a little trouble with a ferrite tuber and the power connector to the hard drive on the power supply. Because the Ferritknolle only has enough space between the fan and motherboard, then the fan is a bit high and gets any contact with the casing cover. All in all solvable with a little correction Press. To avoid noise through direct contacts, I have attached in the appropriate places small self felt strips. In operation, however, everything is ok. When starting the Dreambox the fan spins up briefly times to make itself felt (probably a test). For normal operation, it still requires an enigma plugin which controls the fan (eg "tempfancontrol"). A speed of up to 1500 rpm is in normal operation absolutely not disturbing, even if you close rangeht with the ear to the box one hears him hardly. Below 1,000 rpm, the operation of the fan can even only guess by looking. Conclusion: Equipped something fricklich, fan is very quiet in operation.
