I can confirm that this also has passed on to Oneiric. Also, I think this constant low fan speed HAS indeed caused some system damage from long-term high temps.
I'm seeing periodic failures of the wireless card after the system has warmed up for a while. After doing some checking I noticed via sensors that the temps were hitting ~85 degrees C and hovering there with the fan set to auto. Since this doesn't adequately cool the machine down, I think it's caused the wireless card to become flaky (this is the second wireless card I've had in the machine).
I've since set the fan to disengaged and it's currently running on AC at ~5400 RPM and the system is MUCH cooler (around 70 deg C).
This morning, the system had heated up to 97 deg C before I realized what was going on. I've not hit the 100 deg threshold yet (or not in a long time) but my x201 is also a Core i5, so that may account for it not heating up as quickly as an i7 will.
