cpufreqd as standard install?

[John Moser]

Has anyone considered cpufreqd in standard install?

I have a 1.9GHz Athlon 64 X-2 with stock heat sink (recently cleaned and 
inspected) and fan (operating at 3200RPM).  Its clock rates are 1.9GHz, 
1.8GHz, and 1.0GHz.

At full load (encoding a video), it eventually reaches 80C and the 
system shuts down.

I currently have cpufreqd configured to clock to 1.8GHz at 73C, and move 
to the ondemand governor at 70C.

At 73C, the system switches from 1.9GHz to 1.8GHz.  Ten seconds later, 
it's at 70C and switches back to 1.9GHz.  41 seconds after that, it 
reaches 73C again and switches to 1.8GHz.

That means at stock frequency (1.9GHz) with stock cooling equipment, the 
CPU overheats under full load.  Clocked 0.1GHz slower than its rated 
speed, it rapidly cools.  Which is ridiculous; who designed this thing?


Besides this, it would be possible to enter power save mode on laptops 
and UPS based on battery life remaining.
