So I decided to finally lash out and replace the $40 second hand Koolance D5 from ebay that I use in my system. The Koolance arrived in good condition apart from the fact the previous owner had somehow forced the speed control dial and it just spun freely without changing the pump speed. I could make it work but it required a lot of force to be applied to the control dial. Anyway I wanted a new one and thought some pics might be of interest. Click to view full size!

I have a slight issue with this because my bayres is overhung by my fans ... everything just fits though. Click to view full size! I took the time to sleeve the power wires so I don't have to take it out later. I'm a thinker, I am. Click to view full size! This is the important part of it all. The Aquasuite 2012 software is amazing and incredibly powerful. I have an Aquaero pro on the way so all this stuff will get much more detailed and complicated when it is integrated. For now it provides access to the pumping power controls and speed readouts, along with water temperature. Its so luxurious to be able to change the speed of the pump without half dismantling my PC and forcing a dial only to wonder at where it will end up being set at. I guess in the end they are very expensive for a D5 pump. With my old one I really just set it once and never worried about it much. However if you already have an aquaero then why not spend a bit more for the extra controllability.
