I don't think it will help you overclock that much, but I do think it will help with system stability, by lowering overall system temps. Which COULD, not WILL lower CPU temps. Some may see a drop in CPU temp, while others wil not. 9mm does have a point. Although I wouldn't say it definately won't make a difference, I wouldn't expect too much out of it unless your pushing the bleeding edge, and are fighting for that 1-2 Mhz gain. It's still a cool mod in my books, wether it works or not. Does it work? You got a saw, an extra fan, and some free time? Those of you brave enough to try, post your results. If I get enought free time to put one in , I'll post some results as well.
