    You notice it looks a lot like the swiftech pump? Or the Danger Den pump?

    It's a Laing pump. They are all the same.

    Koolance as the cheating marketing ******** they are even bump the head preassure up to 7m instead of the official Laing numbers. Maybe because they use a 13vdc Power supply. Got one of those?
    I want my old title back.
    Old beast is torn down.
    Will update later.

    you split the flow before the block and video and then rejoin them. a bit more tubing that way and uneven flow . you might want to get some extra hose and do a comparison by routing the flow to cpu then to video then to rad all in series and see which performance you like better
