    Hi,

    I'm going to (try) apply a thin copper sheet between my gpu and heatsink, the so called 'copper-mod'.

    Now i ordered 2 copper sheets, and they are wayyy to big so i need to cut them down to... well i don't know yet, maybe like 15mmx15mm

    Right now they are 10 cm x 10 cm.. how can i cut these things?

    Grtz

    with metal cutting sheers

    Edit: use a deburring tool on the freshly cut edges. (not needed really but it will be more safe).

    local hardware store maybe?
    Also I think I misspeled it, probably spelled shears.

    Just take one sheet to show someone at the hardware store and they should help you find the right tool.

    You can use Tin Snips or metal shears.
    You can use a file, or fine sandpaper to remove any burrs.

    If you find that the metal is not flat after a cut, you can do one of two things:

    1) If you have lapping stones, throw down 600 grit lapping powder and place the copper piece on the lower block. Put the upper block on and continue until the surface is a continuous color. Shiny marks indicate peaks in the piece. Continue until the piece is flat

    2) if you really just want to get it flat quick, use a ballpeen hammer and flatten it out. Only use a hard flat surface, if you use this method

    Seems a little thick to be doing intricate cutting with metal shears, get yourself a hack saw and clamp that thing in a vise (wrapped in a towel to prevent damage to the copper).

    1 to 1.5mm thick is ideal for a GPU/heatsink copper mod. The one I'm using right now, thanks to K-TRON, is 14x14x1mm.

    What did you use to cut yours?

    Or didn't you have to do any cutting?

    No, I got mine from K-TRON already in that size. He's probably got a few more for sale, ask him.
