The best way to distinguish wether or not a cooler is fitting you card is to check it with the height restriction drawing.

To use the higt restriction drawing please meassure the distance between the mounting-holes around the GPU. You can meassure the distance at the backside of the graphics card, so there's no need to unmount your stock-cooler to find out if the new one will fit or not. You will see that in most cases the GPU is surrounded by four screws which are in a square-form.

This picture is showing the backside of a graphics card. The distance between the holes is about 53 mm.

With help of the hight restriction drawing you can check if the holes will fit with the cooler's mounting-clip.

Please take note, that this drawing is showing the socket of Accelero S1 Rev w. Please check the linked height restriction at the base of this atricle in order to get the values for your specific cooler.

The distance between the holes is 53.4 mm which fits perfectly with our graphics card.
If no other components, such as high capacitors cause problems, there's nothing to keep you from mounting your new cooler.

Here you can find the hight restriction drawings for our recent coolers.
