Then, do the testing? You will have to track it by thermal only. If the problem doesn't show up, we will know for sure that it is Linux doing something wrong. Then, you can repeat the tests with only the fan module and only the thinkpad-acpi module, to narrow down the problem. -- "One disk to rule them all, One disk to find them.
