    Hi All

    I decided to pull my old X58 out of the cupboard as i found a fix for the mobo and it runs as per normal. I ended up buying two second hand GTX690's for extra cheap plus free postage.

    I ordered two bykski GPU water blocks after reading some reviews and watching a few youtube videos on that brand plus they are the only one's selling water blocks for a GTX690, but need some help with choosing a suitable pump as I've never done liquid cooling for CPU and SLi.

    Thanks

    Well my first question wouldn't be so much what pump is suitable, rather how many radiators will you be using and what manufacturer are they...?

    a) 690's in SLi are going to produce a sh*t load of heat to dissipate.
    b) Some radiators are more flow restrictive than others (some CPU blocks and most certainly GPU blocks will further kill flow rate).
    c) Dependant apon how restrictive your loop is will then dictate your choice of pump.

    thanks for the reply but I haven't chosen any other parts as yet but radiators are well priced so I'm not too concerned about which one's to buy. How about something like

    1x EK Coolstream PE 360
    1x EK Coolstream PE 240
    Thermaltake Pacific W4 CPU water clock.

    Feel free to recommend some parts.

    EK Coolstream PE's are meh in terms of cooling and are only designed for push config fans, front and backing them wont gain you much performance boost either - personally if I were going for rads of that thickness I'd go with HWLabs Nemesis GTS's.

    In terms of cooling, you should ideally spec 120/140 of radiator surface area per CPU/GPU to be cooled plus an additional 120/140 buffer; in this instance by using a 360 and 240 your running the bare minimum.

    I have no first hand experience with TT CPU blocks, my own preference has always been Aquacomputer; what CPU are you cooling? Are you intending on overclocking?

    Given the level of loop restriction I'm thinking you'll need a pair of DDC's LINK, a single DDC or D5 won't do the job and you'll need the head pressure of the DDC's to overcome the flow restriction.
