Hi Dave :) I guess the fan is controlled by the BIOS and not by the kernel or any Linux application, I guess it's an ACPI function.
I don't think that ACPI is turned off. I'm still with 64 Studio 2.1 and here my dual core always runs with full speed, while for my Suse the CPU speed is managed to fit the load. If the CPU always runs on full speed, the CPU gets warmer and the fan will run faster. I guess this is the reason why your CPU is running faster, while you are using 64 Studio. It's possible to change this, but maybe it's better for audio performance to run the CPU always with highest frequency.

Greetings, I'm getting excellent audio and video results from 3.0 beta2. I've built, installed, and tested Csound 5.10.1 with fairly complex realtime audio output. No xruns at all with my UA25 and Daniel's suggested settings (8 msecs latency). Great work, my compliments to the chefs. However, one last niggle remains (well, maybe it's the last one). My machine also runs Ubuntu 8.10 from another partition on the disk, and it runs much quieter with Intrepid than with 64 Studio's Hardy . Is there a CPU fan control in use in 8.10 that wasn't in Hardy ? Can someone explain why this is happening and/or suggest a fix ? I can live with it, but the noise is aggravating. Best, dp _______________________________________________ 64studio-users mailing list [email protected] http://lists.64studio.com/mailman/listinfo/64studio-users
