Mounted on the MSI GF4 Ti4600 the FrostyTech
GF4TEC makes itself known, but we still don't have a fan grill on that
Delta. And no, I'm really not concerned
about the lost PCI slots, of which we counted five on the Epox 8K3A+.
There are a few more shots of the completed cooler and videocard in the
forums if you want a closer look.
We did a few tests of the GF4TEC with the card in the AGP slot,
and just resting on the table. After running the cooler for
about 10 minutes with the card just sitting on the table we were able to
get the temperature down to about -6 degrees Celsius. Frost formed on the
copper block, and I'm sure if we had left the MSI
GF4 Ti4600 to sit there for a bit longer it would have begun to frost
over on the rear as well. The interesting thing is that when the card is
in the AGP slot the lowest the temperature would go was about 0 degrees
Celsius. Keep in mind both test were done with the computer off so there
was no thermal load.
It seems that since the air exhausts downward, as opposed to
upward or off to a side there is a small problem with back pressure.
The air moving through the fan, and consequently the hacked up Alpha
heat just can escape as quickly as if the unit is sitting flat on a table.
Unfortunately there isn't much we can do to correct this without swapping
to a smaller sized fan.
