Compatibility and Installation

Despite the Accelero Xtreme 7970 model name, the new cooler is compatible not only with the Radeon HD 7970, but also with AMD Radeon HD 7950, HD 7850, HD 7850, HD 6970, HD 6950, HD 6870, HD 6850, HD 6790, HD 5870, HD 5850, HD 5830. In order to determine if the cooler is compatible with a specific graphics card, Arctic offers two detailed schematics on their company web-sites with all cooler dimensions:

They will show definitively if Accelero Xtreme 7970 will or will not fit onto a given graphics card.

The actual installation procedure is described in detail in the following manual and starts with dismounting of the default cooler. For our today’s test session e selected MSI R7970 Lightning graphics card with the original Twin Frozr IV cooling system:

Testing graphics card coolers on a unique platform like this has a lot of advantages. Namely, this platform has enhanced voltage regulator circuitry and boasts increased overclocking potential. On top of that it is also possible to monitor the temperature of the VRM components and video memory chips, besides the actual GPU temperature. This will allow us to fully investigate the efficiency of the graphics cards coolers in general, and Accelero Xtreme 7970 in particular.

Moreover, a solid heat-spreader plate will allow us to do without the included aluminum heatsinks:

We had to remove the “GPU Reactor” stabilization module on the back of the card in order to attach the bundled backplate:

Luckily, it didn’t affect graphics card stability at higher clock speeds. Now we can put the padded backplate in place:

To avoid any possible backplate shifting during installation, we use plastic stick-on bushes on the inside. They also ensure that the plate gets evenly pressed against the card on all sides:

Once the cooler has been installed onto the graphics card, it looks even more massive and promising than with MSI’s proprietary Twin Frozr IV cooler:

The card with Accelero Xtreme 7970 installed will block two PCI slots next to it and will become 35 mm longer:

Note that Arctic Accelero Xtreme 7970 is 288 mm long.

At the same time, I would like to mention that the cooler doesn’t block the access to additional power connectors, which is often the case with many alternative VGA coolers:
