Hello, I have just purchased an IBM ThinkPad T42. Most of the noise it makes comes from the CPU fan. This is very quiet when the computer first turns on, or when it comes out of sleep, but usually after a few minutes it goes into a different mode. In the new mode the fan is loud, and worse, it "revs" every few seconds - so rather than making a constant noise, there is something of a rhythm to it which I find annoying. I'm wondering if there is a way to control the fan to keep it from doing this. I have the processor running at the slowest speed, so it shouldn't be producing too much heat. There is nothing in "/proc/acpi/fan/", I'm not sure what to make of that. # uname -a Linux fly 2.6.12-9-686 #1 Mon Oct 10 13:25:32 BST 2005 i686 GNU/Linux # cat /proc/cmdline root=/dev/hda1 ro apm=on acpi=on nolapic quiet splash Thanks, Frederik - To unsubscribe from this list: send the line "unsubscribe linux-laptop" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
