Before installing this cooler on the graphics card, you have to remove the protective paper stickers from the aluminum sides of the cooler base and stick the corresponding plastic pads onto corresponding retention holes. These pads will protect the graphics chip from edge damage:

And then you have to fasten Accelero S2 cooler to the PCB with the accompanying screws and carton washer-pads from the bottom of the graphics card.

The passive heatsink installed onto a GeForce 7600 GT looks as follows:

A pretty massive-looking thing, isn’t it? But what is really important, despite the big size the heatsink is unusually lightweight. Accelero S2 is hanging about 4.5cm beyond the upper side of GeForce 7600 GT PCB, and about 1.5cm beyond the right side of it (note that these numbers may be different on other graphics cards).

Before you screw the heatsink to the graphics card, do not forget to put the aluminum heatsinks on top of the memory chips, because it will be a really hard task to complete once the cooler is installed.

There is at least 1.5cm if free room between the installed Accelero S2 cooelr and the GeForce 7600 GT textolite:

The last thing you have to do is to install two plastic locks that fit in-between the heatsink plates, catch onto the upper edge of the PCB and get locked with two special clips on the front side of the cooler. However, I didn’t do it, because I believe that very light weight of the cooler and reliable screw retention can hold the whole thing in place just fine. However, it is very nice to know that the manufacturer thought about it and offered this additional option.

Arctic Cooling also offers a special Turbo Module that consists of a plastic frame with a couple of 70-mm fans sitting on it. This module is intended to magically turn passive Accelero coolers into active ones that can cool not only the chip but the entire graphics card much more efficiently. According to the manufacturer, Turbo Module allows to reduce the chip temperature by about 14o C.

Unfortunately, this Turbo Module is not supplied with the new Accelero coolers and we didn’t get it in time for this tests session. However, we still managed to find an active cooling solution for our S1 and S2 models. It was a very simple and at the same time efficient choice: we installed a 120-mm fan on top of the heatsink:

Note that I simply tightened the fan diagonally to the cooler heatpipe on one side and plastic retention of the Accelero S2 cooler on the other side with plastic ties. This will do the trick as a temporary solution for our today’s test session, however, for more long-term use you will have to figure out something more reliable and long-lasting. I would also like to add that since our 120-mm fans is a pretty low-speed one (~1200rpm), we managed to keep our cooling system pretty low-noise.

This is what GeForce 7600 GT with installed Arctic Cooling Accelero S2 looks like inside a system case:

And in conclusion I would like to point out one more thing. Before installing Accelero S2 do not forget to put in a rear panel bracket with vent holes instead of the solid one that sits next to your graphics card. It will improve the removal of warm air from the system case (which is also true for the S1 model).

Accelero S2 cooling solution is currently selling for $22 USD.
