The northbridge fan on my IS7 is slowly going out, but as I looked at it, I'm not too familiar with the mounting type. One of the replacement kits I ordered won't work, as there aren't holes in the right places on the board (oops, -1 for not taking time out of my busy schedule to do the research). I was hoping I could save myself some time by seeing if anyone here has replaced theirs, and find out what you got? Thanks so much for your help!
