    Just a quick question...

    I have an old GTX295 with a waterblock on it, never used it and no idea if it still works. I want to change the cooling but I don't want to spend the time unless I know it works. So would it be safe enough to plug it in, see if it posts then turn it off? I know merely posting doesn't mean it's completely working, but at least it means it isn't a complete brick.

    Thanks

    Yes its safe however a second option is to fill the block with water seal off the ends so the water is in there and then try it. Get it to psot screen then shut her down won't do damage.

    get a desk or pedestal fan and just blast air at it, as mentioned just get it to the bios and turn off. should be safe.

    Go for it. Tested a ton of cards to see if they boot with no heatsink at all :lol:

    Your good for about 20sec's. Then they really start to heat up.

    so you add a little extra thermal mass, but add a significant risk of damage if the thing does happen to heat up too much.

    if it gets hot enough (say there's something really wrong with it, or your 20 second POST turns into 10 minutes as you get distracted, or decide, POST was fine, lets try Windows), the water will expand as it's heated, being sealed, may potentially burst the seal/o-ringss and leak. (yeah that's an extreme, but possible, outcome)

    I'd just leave it empty - no risk of bursting seals, and the added thermal mass of a few ml of water will make next to no difference to what run time you could get out of the card anyway.

    Can confirm, also done this dozens of times.


    Which GTX295 do you have? if its the dual PCB one and it still posts please sell to me.

    Haha, that question was for OP.
    I went to turn my dual pcb on again last night, got a red light and no display. :-/

    --Apparently a power issue, cant imagine why my AX1200 would have a problem with it. Same PSU powered on dozens of different cards and under ln2 OC.
    --Nope, apparently I need the correct SLI bridge format, which I suspected I had wrong.

    Ignore this link, its more for me than anyone else.
