    Default 3870x2 or 4870x2 WaterBlock screws Shorts the Video Card?

    Hey Folks...
    okay so i have 1 of those 4870x2 EK waterblocks and i've yet to install them hopefully this weekend as my 2nd Rad from Swiftech just arrived

    I've read here : http://www.overclock.net/ati/388361-...functions.html
    This guy is having lots of issues with the Screws actually Shorting the Video card after the installation of the waterblock

    i dont hear much about these kinda stuff happen a lot? Just trying to find out for those ppl whom are using waterblocks on their video cards ever have any issues?

    BTW the guy fixed the shorting issue with some motherboard/Paper washers

    Well I installed my block without a single washer (none were provided...) and it works fine. If you have those washers then of course use them. But I'v read through the forum you mentioned above and another conclusion came to my mind. From the description they were givin there they all were tighting the screws on the cards so heavy that the bit between the barbs was WARPED and it was touching the block itself !. So i guess that might have been the problem more likely. It all depends how you install the block... When you'll have it on check on the side that PCB is straight and it should be fine!

    edit: even on the pictture you\ve put the PCB looks a bit "wavy"

    First of all, I don't know how the guy can use normal paper as insulation. You should use firebre glass washer or rubber, too be safe you should use washers. Yes I do hear some people complains about the screws shorten the card.

    The common issues with fullcover block is over tighten, especially if the block don't have standoffs. Just stop tighten as the screw feel tight even you know there are still couple more turns.

    guys thank you so much for your advise yeah ... it looks as though i should not over tighten the waterblock to prevent warpping and shorting the video card

    i will also be using those orange washers between the screws just in case
