I ran avidemux for a bit last night, to bake in some sub-titles. The core temperatures reached 80 degrees, and then the fan turned on to full, which was really loud, and didn’t sound very good for the fan.
Two methods were able to reduce the temperature:
- the best method was to install the cpu frequency scaling applet, and assign both cores to ‘powersave’
— this reduced the frequency from 1.3GHz to 1.2GHz, which doesnt sound a lot, but which had a huge effect on temperature
- it is possible possible to use schedtool to assign an application to a single processor core
— actually, this was a lot less effective than using the frequency scaling
— syntax: schedtool -a 0×1 pid
When I am at the computer, I will simply use the frequency scaling, since that reduces the temperature significantly. If I’m leaving avidemux to run unattended, I will use both frequency scaling and schedtool to make sure the computer doesn’t burn out whilst I’m not looking.
