Got mine today and I was just wondering the same thing. My fans are always running on slow speed too. I didn't notice it at first I guess, with the other machines in my office running. I am assuming this is normal for this laptop.
I was looking into using I8kfangui to control this. CPU never seems to get above 25C during normal use and GPU registers 38C. Could somone please enlighten me as to how you have this set up?
