That is interesting, because the fan on my X200 is running just over 2000 when idle (X200 is a small machine that runs relatively hot), but is almost completely silent; I can barely hear it (and not just because the air-force destroyed my hearing...) Perhaps it would be good for others who have running T400 machines to provide input on how loud their fans are at the same speed. Perhaps the fan has a faulty bearing, or maybe it is just fouled up with dust, grease, etc. If I remember correctly, the fans on T400 are not too hard to replace, if you are the kind who likes doing stuff like that. If you end up taking the fan out, you could clean it with a de-greaser spray, add a lubricator and check again. -- "Cut your own wood and it will warm you twice"
