Comment 22 for bug 213818

So far:
It took me a while to get Windows running properly, hadn't booted into it for a couple of months now. Using the Thinkvantage tools I'm at least able to throttle my CPUs down, resulting in drastically lower temperatures. I'm not sure how much this was affected by my blowing through the fan to get some dust out beforehand, though.
Sensor 1: 47C
Sensor 2: 62C
CPU0 & CPU1: 47C
It was good to hear the fans spinning up for a change, too. On the other hand, the only acpi application I could find right now doesn't see any fan information, which boggles me a bit - Ubuntu didn't have a working custom DSDT file, yet did at least get fan information though it couldn't set it.
Will test with some LiveCD tomorrow.
