With thinkfan not running, the fan is on BIOS control. This usually give a conservative control with the fan running more then needed. Check if the fan is running at high speed while computations. If it does, the problem is propably caused by other things: - Some systems have insufficent cooling by design and expect some driver (usually Windows only) to throttle the CPU on higher temperatures. That usually isn't an issue on new thinkpads. - The cooling may be reduced by dirt or mechanical issues - The effect may appear only right now because some optimisations may reduce CPU idle or introduced more efficient multi core usage.
