For those of you that skipped straight to this page, the ambient room temperature was between 21°C and 22°C.
You can get the rest of the environmental information at the
bottom of the first page.
There are a lot of results below and on the following page so I'll keep
comments to a minimum. Suffice it to say, the cooling results were impressive.
Side note: although not apples-to-apples, you can get a general idea of the improvements
over air cooling from two of my recent reviews using the same motherboard,
video card and
CPU.
This page will contain results at default clock speeds for both my CPU and
GPU. I recorded the maximum ambient case temperature during each benchmark as
that greatly affects the other temperatures. The next page will have results
from overclocking the 6800 Ultra to 470/1250. Time did not permit benchmarking
with the CPU overclocked.
I ran each benchmark with my 120mm radiator fan on both low (71 CFM @ 1800
RPM) and high (85 CFM @ 2200 RPM) settings.
