Better ask around in the linux-thinkpad ML from other T61 owners, but my first guess is that you have a thermal hardware problem, and that Lenovo will have to fix it for you if till under warranty. My guess is that the thermal coupling is bad somewhere. Probably el-crap-o thermal glue failed between the thermal sink and the CPU die. It is a very common failure mode... > Another issue is that level "7" is roughly 3400 RPM, whereas > "disengaged" spins the fan at about 5400 RPM. Shouldn't level 7 be > closer to disengaged? Ask Lenovo. But it is not close, at all. My guess is that the difference between level 7 and disengaged is the extra hardware punch needed to keep level 7 at 3400RPM as the fan ages and gets clogged. The levels *are* RPM-based. So, if the fan controller has to up PWM to 100% duty cycle to try to get to the RPM it wants, it will do so. -- "One disk to rule them all, One disk to find them.
