Never used a fan controller before so forgive me if this seems noobish.... You might have seen me askig for help on shutting up my PC on here and fan controllers were mentioned, so I'm gonna have a go. My PC has 7 fans, the 3 big ones built into the ATCS 840 and 4 Enermax Magma's. Dug up an old issue of CPC and the 2 top rated fan controllers are both 4 channel, so I was gonna split my PC up like: Channel 1: 1 x Stock (Front) Channel 2: 3 x Enermax (Mid) Channel 3: 2 x Stock (Top) Channel 4: 1 x Enemax (Rear) Research shows the voltage of an Enermax fan is 4.8W, and my stock fan says on it "12V, 0.4A" so that works out it should also be 4.8W. With this in mind my highest loaded channel is 14.4 W (4.8 * 3)...is this right?, I have no idea if watts stack like that. On that basis the Akasa Fan Control Pro with 17W per channel should work just fine, because 14.4 < 17....again am I still working this out right? I have know idea if watts work as simply as that so if someone could confirm that's right?
