#89

This is not a hardware specific issue. Some people here have ATI
graphics or AMD chips. I have a nVidia chip with a dual core 2.4ghz
Intel. The heat control on Jaunty was changed, the fans stopped
the oscillated "breathing" which to be honest was annoying. All of
the evidence i have seen is that if you have a powerful system then it
will overheat more often. This is a very easy to problem to
reproduce, just run any heavy process of your choice the system will
die. ~82.0°C I hit 104 and shutdown just about every day until i
wrote my python hack. I haven't had my system over heat sense then,
so this is PROOF that the fan speed is too slow. This is a very
easy problem to fix, just speed up the fan.

So maybe like 4 people on the planet including me have a fix for this,
too bad everyone else is getting FUCKED while you guys chase your
tails. This problem is so obvious it HURTS.

Peace out.

This is not a hardware specific issue.  Some people here have ATI
graphics or AMD chips.  I have a nVidia chip with a dual core 2.4ghz
Intel.    The heat control on Jaunty was changed,  the fans stopped
the oscillated "breathing" which to be honest was annoying.   All of
the evidence i have seen is that if you have a powerful system then it
will overheat more often.   This is a very easy to problem to
reproduce,  just run any heavy process of your choice the system will
die.  ~82.0°C  I hit 104 and shutdown just about every day until i
wrote my python hack.  I haven't had my system over heat sense then,
so this is PROOF that the fan speed is too slow.    This is a very
easy problem to fix,  just speed up the fan.

So maybe like 4 people on the planet including me have a fix for this,
