I took a 92mm cpu fan from a computer heatsink that runs at 3500rpm and fitted it to the Xbox Cpu Heatsink. I then did the mod that channels air through the GPU heatsink more efficiently and split the fans one for each heatsink. Next I wired the fans to a 12v source but decided these were too loud to be on all th time so I put a switch in so now the fans can be swapped between 12v and 5v so i can have them quiet or loud. This mod cost me £8 for all the materials and it was well worth it, as I've not had RROD for 2 months. Not bad for a console that cost me £1 Here are some pictures of it and soon I'll mod the case to fit the fan later but I have'nt the time currently. If anybody has any questions, improvements or even information or pictures of their own mods I'd be interested to see them.
