    I'm making a water cooling system for my friend's computer with i7 processor. The cooling block is basically 3 parts, a copper plate that's fixed to the processor, an 'injection plate' which guides the water through the copper plate and a plate on top to attach the pipes.

    Here's the injection plate, just done with my CNC router ... not the milling machine!

    Took quite a while to make that - mainly due to needing 7 different tools (milling cutters from 2mm to 10mm and drills) and machining on both sides. The actual cutting time wasn't too bad.

    It will be anodised next, and the copper part nickel plated.

    now that's quite impressive

    nice one man... 10mm!!! looks quite clean, have you lowered your gantry ?

    I think when I finish my CNC, I'll make a water Block for My GTX 460.

    I'll do it with a 0.5mm bit.

    if I can that is... all copper though :)

    Also, I have a Tap here for 1/4bsp.

    You can borrow it if you want :)

    it will cost you shipping there and back.

    Thanks for the kind words. The 10mm cutter was used on the router to reduce the thickness from 12.7mm to 10mm (part is 110*110*10mm)... I used 0.8mm depth of cut.

    I'm going to use a 0.5mm slitting saw - bought one from Arc Euro recently. It's cheaper than the slot drill and much less likely to break.

    Thanks for the offer with the tap, but I think we're going to use the M14x1 tap I have as it's less restrictive.

    I didn't think they did water cooling connectors in M14. you may find you struggle finding compression fittings.

    and this is the only thing I can see a 4th axis being useful for! :)

    They don't - I'll make them.

    I may well use the 4th axis for slitting the copper block.

    Some progress with this - here's the block that holds the pipes with decorative engraving done with 0.8mm and 2mm tools:

    Also done the copper block that sits on the processor, but no photos of that yet.

    Cooling block for motherboard and graphics card to follow shortly ... need to buy some 6mm (or so) aluminium. I'll probably get this as it looks useful:

    nice work.

    Have you got the parts anodised, i have just started anodising my self with some great results.

    i think you might have sealing issue with the o ring groove due to surface finish.

    i would avoid nickel plating the copper as it will affect the thermal transfer.
