Sorry, I was thinking you work for a company with a name like your username :-)
When I bought my 2002 X last year the fan was broken - seems to be a normal thing after that years. On yours (but that is not a professional answer) it seems that your FSR is shot. There are a lot of articles here regarding that problem.

Good luck,

Helmuth
