Product Description

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.
Examples of installation

  • Material: black anodized aluminum extrusion
  • Dimensions (Inch): 7 1/2 " (L) x 3 5/8" (W) x .7" (H)
  • Dimensions (Metric): 162mm (L) x 92mm (W) x 18mm (H)
  • Weight: 8.4 oz (238 g)
  • Installation: high thermal conductivity pad for memory and direct-touch for power MOSFETS (Arctic Ceramique included).
  • Pre-existing mount holes for optional 80mm fan (2 in diagonal)

Critical information:
The PCB revision numbers noted below represent the deciding factor to go by when selecting your Swiftech product,
rather than the brand and/or model number of the card.

Please carefully inspect your card to locate the PCB revision number. All brands using AMD reference PCB's normally
print this number on the card. It is usually located immediately above the gold PCI contacts (GPU side of the board).
Here is an example showing a PCB number 109-C20547 (the -00P at the end can be ignored)
Caution: 1 digit may make the difference between supported or not supported!

Running Smooth
Terence Meadows (Montreal, Quebec) 3/15/2014 9:01 AM
I bought this directly from swiftech in an attempt to use it with an incompatible universal water block which matched the rest of my setup and I used barbed fittings instead of compression. I had to file down the heatsink over top of the memory which worried me a little. When I was finally done I got everything up and running but I have had no problems even though there is a significant reduction in the metal over the memory. Everything is running nice and cool with the CPU and GPU on the same loop, both at temps around 32 and 38 respectively. This thing does not look quite as ugly as it does in the pictures either. I actually like the way it looks. Not as preferred as a full cover block though. Highly recommended.
