Well it I broke down and bought a T7200 Core 2 Duo processor to put it in my M400. The install went smoothly, almost too smooth...;-) Everything is installed but it seems that the 1.8W bios no longer keeps the fan noise down :-(. Unfortunately I got too confident that the bios thing would continue to work that I uninstalled my fan hack. Now the noise is worse than before.... It is getting late here so I will not get into too many details. I did snap a few pictures that I will post later. To be continued....
