[LAU] Balance between performance and noise

Hi, When I set cpu scaling with sudo cpufreq-set -g performance, I have the best proaudio performance on my thinkpad T61. But, that will also heat things up very quickly with as consequence more sound from the fans. The laptop is more silent when I use, sudo cpufreq-set -g ondemand, but I get more xruns then. Is it possible to adjust the ondemand settings to find more balance between performance and noise? How? Btw., I use thinkfan to control the temperature and fan speed http://thinkfan.sourceforge.net/ My /etc/thinkfan.conf settings are: sensor /proc/acpi/ibm/thermal (2, 7, 8, 0, 0, 0, 7, 0, 12, 5, 5) (0, 0, 54) (1, 50, 57) (2, 52, 59) (3, 54, 63) (4, 56, 65) (5, 59, 66) (7, 63, 32767) Thanks in advance, /r
