   Part #: MC8800-SET

Features    [ Edit | History ]

The MC8800 SMC kit is a companion product to our MCW60 series GPU water-blocks, and provides a passive cooling solution to critical surface mount components for nVidia's GeForce™ 8800 series graphics cards: I/O chip, memory, and V/Core mosfets.

The kit is composed (13) MC14 heatsinks: (1) for the I/O chip, and 12 for the memory, and (4) MC21 heatinks for the Vcore mosfets.

When coupled with the MCW60 water-block, the kit provides a totally silent, high performance, and relatively low cost approach to liquid cooling of the geForce™ 8800 series cards.

Example of installation of nVidia's GeForce 8800 GTX:

    work well, stick well enough after letting grease set
    Hard to install
    I bought these and wish I had just gotten a UNI-sink for my 8800GTX, they were hard to install. They would constantly fall, I figured out you have to let them set for a few hours before they stick well.

    heat dispersion is good.
    It is hard to get them to stick.
    The compound/glue on the bottom does not stick too great to the chips. putting super glue in the corner of it seems to have worked for most but one actually fell off.

    -seem to dissapate heat as they should
    -easy to modify height if need be
    -extremely bad thermal adhesive
    -price seems kind of high
    They seem to work pretty well disappating heat. However, the high price and crappy thermal adhesive really don't make up for their fairly good preformance. Overall not highly recommended.

    Appear to allow for good airflow, no physical defects noticed.
    Thermal tape is crap, I cleaned my all the spots multiple times with rubbing alcohol and 10/17 fell off, when examined I noticed that they were not even the slightest big sticky! very unhappy now that I have to go buy thermal tape.

    Also I agree that the IO chip is a little too small, but I haven't done any physical testing yet.
    Really crappy thermal tape, IO chip a little small, Otherwise a well machined product.

    - Was able to get my 8800 GTS run y 900Mhz (1800Mhz) for memory.
    - Don't stick well
    - look a bit cheap
    Well, I'am not pretty sure that those ramsink are not the best available. But, it's doing what it need to. I got lot of trouble to get them stick properly and finally got them stick with a little of Arctic Silvers 5. I think that they should give a better heatsink for the IO chip because it is very hot even w/o overclock...
