The award winning passive VGA cooler extends its compatibility to the latest graphic cards
The Accelero S1 Rev. 2 dramatically extends the compatibility to many of the latest graphic cards. It supports high-end to main stream graphic cards including the latest hot selling Radeon HD 3870, 3850 , GeForce 8800GTS (G92) and 8800GT.

The Accelero S1 Rev. 2 now comes with a new flexible mounting mechanism, multiple screw hole sets and modifications to the heatpipes enabling it to fit a wider range of leading graphic cards. As a result more gamers can benefit from adopting the Accelero S1 Rev. 2 which dramatically improves their gaming experience.

To provide passive cooling for high-end graphic cards, Accelero S1 Rev. 2 is a high performance passive cooler featuring 4 heatpipes connected with extra large surface area. It effectively removes a great deal of heat from the graphic cards keeping the components cool. Thanks to the elegant design, Accelero S1 Rev. 2 outperforms active cooling solutions. Accelero S1 Rev. 2 creates a true industry leading zero noise cooling solution for all enthusiast gamers.

Accelero S1 Rev. 2 features 4 thick copper heatpipes which connect directly from the GPU core. The heatpipes with sintered powder wicks provide ultimate heat conductivity. Heat from the GPU is rapidly dissipated through 32 fins that extend beyond the height of the graphic card. Optimized fin design allows better air flow thus removing the heat more effectively. Together with the bundled RAM heat sinks and voltage regulator heat spreader, Accelero S1 Rev. 2 provides an all-round passive solution that achieves the best cooling performance.

Never compromised on noise Install and forget about it – No moving parts means it is maintenance free. An extra pair of mounting clips provides extensive protection to the graphic card that prevents damage from improper handling. With the help of the new mounting design, Accelero S1 Rev. 2 is widely compatible with high end ATI and nVIDIA graphic cards.

Accelero S1 Rev. 2 can still be paired with the Turbo Module – the twin fans add-on, which further increases the potential power of Accelero S1 Rev. 2 with enhanced cooling performance under extremely quiet operation. Turbo Module helps boost up the GPU and memory overclockability, squeezing more graphic performance than ever before.

nVIDIA GeForce 8800GTS(G92)* / 8800GT and ATI Radeon HD 3870 / 3850 Compatibility
The Accelero S1 Rev. 2 is fully compatible with GeForce 8800GTS(G92)* / 8800GT and Radeon HD 3870 / 3850 graphic cards. Using the Accelero S1 Rev. 2, both Radeon HD 3870 / 3850 and GeForce 8800GTS(G92)* / 8800GT graphic cards have been tested and confirmed that they operate well within the specifications under full load operation. The Accelero S1 Rev. 2 not o­nly cools both high performance GPUs, absolutely noiseless and maintenance free, but it also achieves a far lower temperature when compared to the standard coolers and thus offers overclocking potential and a longer service life.

To further improve the cooling performance, the Turbo Module - a twin fan add-on, is recommended for all enthusiast gamers.

* GeForce 8800GTS(G92): In order to guarantee sufficient cooling performance, a Turbo Module may be added.

SLI Compatibility
Accelero S1 Rev.2 is compatible with SLI configuration by having a longer flexible SLI cable to go around the top of heat sink that connects both cards. The bundled SLI cable from motherboard is usually not long enough. A 12cm long SLI cable can be purchase in our online Shop if necessary.

ATI Radeon X1950Pro requires an extra Voltage Regulator Heat Spreader Module.

Voltage Regulator Heat Spreader Module
Voltage Regulator heat spreader module is designed to fit for all X1950Pro graphic cards meeting ATI standard layout (reference design). However there are not every graphic card manufacturers following the standard board design. For example some AGP graphic cards have difference layout and some designs basically not required to install Heat Spreader. The following drawings show the ATI standard board layout with Voltage Regulator Heat Spreader installation. Please check your graphic card to have the proper installation of the Voltage Regulator Heat Spreader.

Mod of Voltage Regulator Heat Spreader Module for Sapphire X1950Pro AGP
Since Sapphire X1950Pro AGP card places 2 power sockets o­n the card and o­ne of the power socket conflicts with the Voltage Regulator Heat Spreader Module. Users can cut off a small piece of Voltage Regulator Heat Spreader away to resolve the conflict. Another method is to stick RAM heat sinks o­n the voltage regulator for heat dissipation.

Compatibility
With this height restriction drawing you can check your VGA board for compatibility with our cooler.
First you have to check the position of the mounting holes. Then check the height of the components.

If some components are slightly higher than our fancasing allows, you can relatively easy cut the fan casing.
To do so we suggest you first to uninstall the fancasing bottom. Then cut the bottom in the area of the component that caused the conflict and reinstall the bottom again.
