Hello, first i flashed my GTO² with that modded 16PP Bios (http://www.techpowerup.com/articles/overclocking/vidcard/127). Everything worked fine, the card still took 16PP and XT PE frequenzy. After that, i tried an Original Sapphire X850XT PE Bios. Freqenzy and PP was like other XT PE, but the fan didn`t work any more! So i flashed it back to the modefied 16PP Bios, but the fan didn`t work. I tried several other bios, like original ATI XT PE. No Chance, the problem stayed. flashproggie is modded flashrom. I read the posts in "articles" forum and i saw no answer or my english is too bad? Sry for that, but i hope for help.
