x61 heat and noise

[alexap]

hello,

i just got my new x61 probably one of the last sold direct from lenovo
i have now x60 and very happy with it especially 12' screen and size therefore wanted to keep same model before its going to disappear
unfortunately i have same problem described here many times

--heat - computer running hotter than my x60
--noise - fan running 90% of the time and much louder than x60, its not a big noise but since i like to work in quite environment its disturbing
--squeaking noise - fan running with very annoying noise

i want a new and faster pc, budget not a problem, but it must be quite and small footprint
should i send my x61 to repair or just leave it as its vaiste of time and order something from new models

by the way what will be the coolest and less noisy x200 or x200s which model?

please advice
thanks for you help
Alex
