With a Fujitsu Lifebook A530 that I lent from the University I had the problem |
37 |
that it can overheat and actually shut down. However, I semi-recently |
38 |
discovered thermald, which has (in its default configuration state) |
39 |
successfully kept it from overheating. It can still get hot where the CPU is |
40 |
(sensors say around 80°C), but never enough to actually overheat and shut down, |
41 |
and with long running emerges, it gets more proactive such that the laptop |
42 |
starts cooling down by 10-20°. Maybe this tool can help further (especially if |
43 |
you configure it explicitly)? |
