[Bug 224876] Re: Hardy does not control the CPU fan properly.
I have a T42, running Hardy Heron, and my fan doesn't go ~1900 rpm. When trying to rip a DVD using handbrake (for person backup of course), the computer shuts down stating that the CPU temp has gone too high. I am unable to increase the fan speed using the command to change the setting in /proc/acpi/ibm/fan. It changes the setting, just not the fan speed... I can stop the fan and start it, it just doesn't seem to go fast enough.

It seems that the CPU is intended to operate in the ranges we're observing.

[Bug 224876] Re: Hardy does not control the CPU fan properly.
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

I thought that my ThinkPad X60s was getting warm. I installed the sensors applet, and it showed that the temperature was creeping into the 80's, with the fan steady somewhere around 3300 rpm (or was it 3600?). Seems rather high/dangerous.

[Bug 224876] Re: Hardy does not control the CPU fan properly.
I might (be | have been) a bit paranoid. Based on information from Intel (listed below) I've found that for my particular processor (T7300 2Ghz) that the specs might be a bit more forgiving than I originally thought. A heat sink compatible with my processor has to be able to dissipate 35W of heat - Intel calls this number Thermal Design Power. The Thermal Specification for the processor is 100 C. Thus, when my CPU is crankin' out 35W of heat, the temperature measured at the joint between the CPU and the heat sink should be no more than 100C. From Intel.com: Thermal Design Power: Thermal Design Power: (Also referred to as Thermal Guideline) The maximum amount of heat which a thermal solution must be able to dissipate from the processor so that the processor will operate under normal operating conditions. Thermal Specification: Thermal Specification: The thermal specification shown is the maximum case temperature at the maximum Thermal Design Power (TDP) value for that processor. It is measured at the geometric center on the topside of the processor integrated heat spreader. For processors without integrated heat spreaders such as mobile processors, the thermal specification is referred to as the junction temperature (Tj). The maximum junction temperature is defined by an activation of the processor Intel® Thermal Monitor. The Intel Thermal Monitor’s automatic mode is used to indicate that the maximum TJ has been reached. -- 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

[Bug 224876] Re: Hardy does not control the CPU fan properly.
It's a different version of the fan hardware (X60 vs. T42p) and a different arch (i686 vs x86_64).

[Bug 224876] Re: Hardy does not control the CPU fan properly.
You might be right. For my T42p the fan activity has reduced after the recent OS updates for Hardy. The average idle temp has gone down from 42C to 37C after the OS updates and the fan activity has reduced to the levels experienced with Gutsy. -- 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

[Bug 224876] Re: Hardy does not control the CPU fan properly.
My last post was not quite correct. The T42p system is cool but the fan is blowing cold air at 3600rpm (approx. level 4) I just didn't hear the fan at the beginning.

My subjective perception is, that Hardy causes more fan activity than Gutsy. I have experienced this on 2x Thinkpad T42p 2373-KYG with Kubuntu 8.04 Hardy Heron LTS installed.
