After upgrading my Thinkpad T400 to Quantal, I noticed that the CPU fan became much noisier, it was essentially running all the time. I have configured fan control through
thinkfan. I suspect that the problem is due to an updated version of the
thinkfan package, now 0.8.1-1. Reverting to 0.7.3-1 sort of fixed the problem, the fan is quieter now.
Did anyone else experience similar problems? Is there a solution short of downgrading?
