Product Description & Info
The HD6970 heatsink is designed to cool surface mount components (memory,
and mosfets) on the most recent revision of ATI Radeon™ HD 6970 2Gb Series
Reference Design boards, as well as (1) HD 6950 2Gb Series reference design
graphics board. Compatible Brand Models and PCB versions are listed
hereafter.
The Heatsink is designed to be installed in conjunction with our MCW60,
MCW80 and MCW82 VGA waterblocks and to allow stable overclocks of these
high-end graphic cards while keeping them cool and silent or very quiet. For
high-overclock applications where maximum voltage is added to the card, an
optional slow speed (quiet) 80mm fan can be added to complement cooling of
the power MOSFETS, resulting in up to 30% drop in these components
temperature compared to stock cooling.
The performance advantage of hybrid cooling which consists in cooling the
GPU with a universal waterblock in combination with a heatsink compared to
using a full-cover water-block solutions is well known among enthusiast
users: improved thermal dissipation at the GPU level thanks to Swiftech's
Diamond Pin Matrix and a better TIM joint, and less heat dumped into the
liquid cooling loop coming from memory, and power MOSFETS since they remain
air cooled. In addition, this combination provides a complete solution that
is more economical than full-cover waterblocks because the GPU waterblock
can be re-used over time with different VGA cards.
The heatsink is a custom Aluminum extrusions, and it is precision CNC
machined to allow optimum TIM joints with the hottest components such as the
voltage regulator modules, where high performance thermal grease is to be
used. Less heat intensive components such as memory receive pre-applied
thermal pads, as shown below.
