Have you done the 80mm fan install, Tyler? I wanted to for a while, but I'm a little weary of all the cutting and case mod involved.

XBTool is a development tool (?) that allows for some editting of bios files. Settings such as the default color of the eject LED, bios size, large HDD partitioning, etc., and (in this case) fan speed can be editted. After which you may flash your mod with.

XBTool (as well as other dev softwares) are available from places like xbox-scene.org.

I'm interested in what's going on, the more I read the original post. I don't know half of what I want to know about the tech side of mods.
