However, I semi-recently discovered thermald, which has (in its default configuration state) successfully kept it from overheating. It can still get hot where the CPU is (sensors say around 80°C), but never enough to actually overheat and shut down, and with long running emerges, it gets more proactive such that the laptop starts cooling down by 10-20°. Maybe this tool can help further (especially if you configure it explicitly)?
