I've just done the test Mike Hix wrote about on both a ThinkPad x31 and a ThinkPad x61 (yes, I love the Thinkpads).
On my X61 the fan will be steady somewhere around 3200/3300 rpm. That is even if it's idle or if I'm doing the sha1sum test. The X31, on the other hand, it's a lot more interesting since the fan is OFF when idle. When I ran the sha1sum test it didn't start before the temperature reached 68 degrees celcius, and then "only" at 3400 rpm. This was however enough to keep the temperature steady at 70 degrees. When I stopped the test the fan turned itself off when passing 53 degrees celcius. Silence is golden. So my question is, why does the fan in the X61 keep spinning at ~3300 even when the machine is staying idle? I must say I prefer the way the X31 handles this problem. Hope this input is of any value. Btw, I'm running 32bit Ubuntu on both machines. X61 is running on Hardy and the X31 is using Gutsy. I can upgrade the X31 and do the same test again if necessary. Heck, I can even reinstall it. :-) -- Hardy does not control the CPU fan properly. https://bugs.launchpad.net/bugs/224876 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
