Hi fuzzyboy, I’ve had a quick search of Google and didn’t find image or definite result in forums etc.
I’ve compared the image of the PCB from Bit Tech with images of stock GTX580 PCB and the fundamental position of GPU etc looks very similar.
I’ve looked at the Accelero Xtreme II’s webpage and noted the comment;
“The cooler is NOT compatible with any NVIDIA graphic cards with double deck DVI outputs.”
However this version II has a cut out to clear double height connectors at the bottom of the PCB, like your card has. The Height Restriction Drawing
suggests need 50mm between the mounting hole and the DVI cover. Counting pixels on the PCB image I concluded you have 49.5mm!
That’s rather tight, if it really is 0.5mm it would probably bend/give that much. I think I’ve read of people with AMD cards removing the DVI cover to gain the few mm to fit Accelero coolers. The rear of the card doesn’t look like it would present any problems. As you have the card you maybe able to measure it more accurately and compare with the restriction drawing.
Or look in to the Thermalright Shaman as an alternate cooler, if the 8 heatpipe 140mm fanned monster will fit your case! Or just get a couple fans and see how it goes!
Good luck, Seb
