You might want to try some canned air on the heatsync attached to the CPU fan, or making sure the laptop is near some aircon etc.After a lot of googling, I decided to tear down the laptop, expose the cooling fan and give it a good vacuum job to get rid of any dust that might have accumulated and was possibly interfering with the CPU cooling. I assembled all the pieces, rebooted and re-run the rsync copy command which this time ran to completion without overheating.

Did you first load the ibm acpi module with the fan_control argument ? rmmod thinkpad_acpi modprobe thinkpad_acpi fan_control=1I had the same issue with my thinkpad, and wrote this [1] to work around it, though in the end canned air was the proper solution.
