Compatibility and Installation

Accelero Xtreme GTX 280 is designed for GeForce GTX 260 and GTX 280 graphics accelerators. However, we are pretty certain that this cooler will also fit the GeForce GTX 285 and GTX 275 graphics accelerators. The only question is if the heatsink plates will fit the power elements. We will be able to answer this question only when these graphics cards arrive into our cooling lab.

Today we are going to install and test Accelero Xtreme GTX 280 on ZOTAC GeForce GTX 260 AMP2! Edition 896MB graphics accelerator:

When we removed the reference cooler, we had to clean and degrease the NVIO chip, memory chips and power elements. The installation manual (1.46MB file) suggests that you should use a soft eraser for that purpose. After that remove the protective film from the thermal pads and stick them onto all components:


The aluminum heatsinks will go right on top of the pads:


Both these heatsinks stay in place very securely (the heatsink covering NVIO and two memory chips is attached with two screws from the back of the PCB). The memory chips on the front of the PCB do not need any thermal pads, because they will be covered with a heatsink that already has sticky thermal interface applied to it:

However, these heatsinks do not hold too well even on clean and degreased chips. The same is true for the aluminum backplate. It is a real pity that Arctic Cooling engineers didn’t think through this particular issue. However, when I accidentally put the memory heatsink onto the aluminum backplate, it took me a while to rip it off.

When all heatsinks are successfully installed, the cooler is fastened to the PCB and GPU with four screws with washers:

This is what our super-cooler looks like when installed onto a GeForce GTX 260:

And this is the same cooler inside the system case:

At least two mainboard slots next to the graphics card should be left empty. As you understand, this cooler will not suit for SLI configurations.
