just wanted to briefly review my be going on, I've bought this product two months ago and I've also read a lot on the internet about it. With me here to run fan 5/120 mm and are controlled by the Aerocool. The installation was very easy and all accessories up to the fan is, the speeds can be controlled super here and also with 5 fans of PC is very quiet thanks to the speed control. Would buy this product again and again and he gets from me a clear Kaufenpfelung,
