I have Linux Mint 16 installed on an Acer Aspire 5740 laptop. The machine has 8 GB RAM, and a 1 TB disk. I have a dual boot setup with Windows 7 - on the Windows side only the OS is installed.
The machine overheats when playing videos or when CrashPlan (cloud and local backup) is running.
I have PSensor installed and I'm constantly having to watch temps. With CPU usage in the single digits, temps are running 50 C. I've seen spikes all the way up to 100 C, and this morning had a thermal shutdown.

I want to keep Linux, because it just works and does what it's supposed to do without drama and without problems - but I cannot work under the constant threat of a thermal shutdown.
I've cleaned the vents to the fan.
