Project 850
A word of warning: If you remove the factory
heatsink of the GeForce video card you will lose the warranty, so make sure you can live
without it first.
The GeForce 256 DDR is currently the fastest 3D video
card on the market. Running at a stock speed of 120Mhz core and 300Mhz memory, it already
has more than enough power to run any games. However, there is always room for
improvements.
To get the most out of the Asus 6800, I removed the
factory heatsink and installed a Mellenger Video Card
Cooling Kit on it. The kit consists of a big heatsink/fan for the CPU core and eight
RAM Sinks to keep the memory chips cool. You will lose a PCI slot with this kit.
To get better performance out of the GeForce and Mellenger kit, I lapped
the GeForce core to bare copper. This ensure a perfectly flat contact area for the
heatsink. Normally the Mellenger heatsink is attached to the core by thermal tape.
However, I decided to tap the heatsink and screw it to the core using the two holes of
either side of the GPU core. This also allowed me to use some thermal compound between the
core and heatsink. The RAM Sinks were installed with double sided thermal tape.
The last item added to the video system was a new ball bearing card cooler
from The Card Cooler. The Card
Cooler provides extra cooling to the main heatsink and also keeps those RAM Sinks nice and
cool. The bottom line on this setup is a GeForce video card that runs stable at 160Mhz
core and 360Mhz memory without any artifacts. It will run at 170Mhz core but artifacts
will show up in Quake 3 within three to five minutes.
