Review: Excellent - Excellent bit of kit
Review: Richtig power - Sehr leistungsfähiger Lüfter hat ordentlich Power ich verstehe, viele Rezessionen nicht so Kunden sagen im gesamten ist es zu laut. Denn dieses System ist eher leise, wenn man es auf Stufe 2 stellt. Auf maximaler stufe, ist es laut ja aber man muss bedenken der Lüfter muss ordentlich Luft wegdrücken meinem Kumpel reichen 2 Stufen locker dabei wird auch viel Luft abtransportiert. Das Verbauen hat auch super geklappt und die Kabel waren mehr als nur lang genug, sodass man alles sorgfältig verlegen kann. Eine klare Kaufempfehlung.
