Bug Description

I'm using a Lenovo R61i (type 7650D6G), with Ubuntu 14.04 and up-to-date BIOS. The fan speed is well controlled on low temperatures, i.e. around/below 50°C, staying between 0 and 3000RPM. The problem is that under a higher load my cores can reach higher temperatures, like 75-80°C, without the fan being speeded up over 3000RPM. Since lmsensors shows 85°C as critic temperature for my cores (Intel Core Duo T5450), I find this quite dangerous.
I have experienced this copying files between two hard disks, being both cores running at 50% for two hours.

WORKAROUND: Use cpu governor.

WORKAROUND: Use fancontrol.

NOTE: this only happens on AC power, for the simple reason that, when on battery power, the cores don't even reach those temperatures even under a very high load (nice feature!).

Same Problem on Lenovo Thinkpad X301.

Workaround: Using tpfanco (Thinkpad Fan Control) and setting fan speed to "full" at a certain temperature.

The difference is essentially the machine model, although both bugs feature several different models in the comments. I reported this bug following the advice in comment #152 from Bug #751689.

Andre, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available (3.15-rc7) following https://wiki.ubuntu.com/KernelMainlineBuilds ?

I am really sad, I tried to boot with the following kernel:
linux-image-3.15.0-031500rc7-generic_3.15.0-031500rc7.201405251935_amd64.deb
and the result was losing the screen functioning. I tried to boot twice, but both times, after a really ugly green stripes screen and Ubuntu loading for some seconds, the screen went blank, without the pointer. I tried to switch to tty1 but with no result. After that I even had difficultes reaching the GRUB, but anyhow I was able to boot into the repository kernel. I'm going to uninstall that kernel, so if you could suggest me a safer one I would follow your advice, but I really wouldn't like to encounter this problem again!

Andre, did this problem not occur in a release prior to Trusty?

Before Trusty i was using Precise, but actually I really couldn't say, since my use of the laptop was much less intense than now, but I never had temperatures problem. By the way I could test the live version if it helps.

Anders Hall, that's not how bug reports work. Despite this, so your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into the default Ubuntu kernel (not a mainline one) via:

Reducing power consumption does in effect lower the temperatures (like simply working on battery power does). I've tried thermald, which kept the cores about 5°C cooler, but didn't speed up the fan (it's not set to do so). I didn't try the tool to increase fan speed, since it's for Dell laptops.
I wonder if it is Ubuntu's policy not to spin the fan over 3000RPM (which I believe is possible), then this would not be a proper bug.

Andre, how about using fancontrol as per https://help.ubuntu.com/community/PowerManagement/ReducedPower#fancontrol (I just added it)?

Yes, that would be the best workaround in this case! Thank you for adding it!
