view/change processor performance, view temperatures/fanspeed

[robh]

G'day all,

I want to write a script that will check the temperature of my quad G5's tunnel heatsink (or maybe one of the other 8+ temperatures available via istatpro, or one of the fan speeds) and then set the processor performance based on it.

Basically, if the machine's real hot and noisy, drop from 'Highest' performance to 'Automatic', and if the machine's nice and cool, crank up the performance. This'll let my background Folding@Home jobs run at optimum speed without unnecessary noise.

Can someone point me in the direction of info on how to access the relevant info so that I can write the script.

thanks.

To get the temperature info, look at one of the open-source utilities that display temperature sensor readings - e.g. "X Resource Graph"

I think you can use the command-line utility /usr/bin/pmset to change the processor speed. Read 'man pmset'
