So right now the pump is not running at 100% ?? The pump is the only thing plugged into th aquaero at the moment, so no issues with aquabus id's I hope. (It's detected,, just doesn't do anything)

Additionally - flow rate is even worse when the aquaero isn't powered - literally just a drip into the reservoir...

So no idea what is wrong - I fear the d5 is simply not powerful enough for my loop... See video here of the very poor flow: http://youtu.be/J7g7t9eSaDM Loop order is: Pump - rad 240 - rad 480 - cpu - mosfet - rad 480 - dual gpu blocks - chipset - res Also changing the pump from 100% to 1% (via aquaero) has absolutely no effect (percentage as given in top right corner on aquaero) - is my pump defective?? Hoping someone can please help! -C
