Given that you have an AMD Radeon HD 6470M graphics chip, it could indeed be the component that is getting hot, although I don't know why your main fan doesn't come on. There are possibly two separate issues here.
There are 3 possible solutions to overcome the GPU overheating: 1) Install the proprietary (closed-source) AMD Catalyst (fglrx) driver. 2) Continue using the open-source driver and enable dynamic power management by writing "dynpm" to /sys/class/drm/card0/device/power_method 3) Continue using the open-source driver and enable profile-based power management by writing "profile" to /sys/class/drm/card0/device/power_method, then set it to either low, medium or high by writing "low", "med", or "high" to /sys/class/drm/card0/device/power_profile. Note that option 2 seems to do nothing on some hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/881593 Title: Hardware temperature hazardously hot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/881593/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
