    If you sure that you didn't break anything when removing and cleaning the fan, and put everything back properly, then there is only one possible explanation I could think of. The first overheating had damaged temp sensor in your motherboard. Making it gives false signal (or no signal at all).

    I suggest to visit nearby toshiba service center to see if they could replace the temp sensor (I doubt it) or the motherboard. Or you can look around for local geek who could replace the temp sensor for you (if replacement is available).
