Modding my old EVGA GeForce 8800 GT video card's fan to blow heatfrom the PC case?

    Hi.

    I have an old EVGA GeForce 8800 GT video card's fan in a brand new Antec
    Sonata Proto mid tower ATX case with two case 120mm case fans, MSI P43
    NEO3-F (MSI-7514) motherboard, etc. See
    http://zimage.com/~ant/antfarm/about/computers.txt for the details for
    this secondary computer. Also, hardwares were cleaned last night from
    its dust pileups after about two years of usage.

    I noticed this video card's fan goes to maximum speed (4,000 RPM) even
    when my computer is idling. I think its air flow is not good in this new
    case. I know my old MSI ATI Radeon 4870 video card (512 MB) blows its
    hot air in the rear, but this NVIDIA card doesn't. Is there a way to mod
    its cooler to blow out heat?

    FYI for my system's sensors:

    I didn't look very hard, but for air, I didn't immediately see anything
    that looked useful.

    They made "slot coolers" in the past, as a means of
    moving a cloud of warm air from the area around a card.
    But this too is a relatively dumb idea, due to the noise.

    http://accessories.us.dell.com/sna/...&cid=255160&lid=4522435&acd=12309163088460813

    That leaves perhaps a water block, and a pump/reservoir/radiator kit that
    sits outside the PC, as a means to move the heat outside. It all depends
    on whether newer cards and the 8800GT, share mounting points and chip
    height, as to whether a water block of appropriate design is available
    now. Specialty parts, you wouldn't expect any small retailers to stock
    a lot of them.

    You can still use some cooling for the surface of the card,
    once the water block is in place, to help the regulator stuff,
    or the RAM chips. Simple fans would do for that. It would only
    call for RAM sinks, if there were obstructions in the way, and
    you were having problems getting a decent air velocity.

    The problem with fans, is finding a means to hang them inside the case.
    When cooling a card surface, I use an aluminum strip from the hardware
    store, drill a single hole in the end, and put a PCI slot screw
    through the hole, to allow the strip to be bolted to the slot retainer
    area. Then, a single lightweight fan, can be fastened to the strip with
    nylon ties. Maybe an 80mm for example. If there is too much weight, you'd
    need to extend the length of the strip, and find a means to bolt down the
    other end of it.

    Correction. It is over 5K RPM that is loud and a bit warmer than my
    older case:
