One thing is that the T420 is not sold as a consumer laptop. Under Windows, running AutoCAD/SolidWorks will drive temperature of 90+ degrees. This laptop is suppose to be for those kind of work. Furthermore, I'm not even running heavy games. I'm running things like FTL, or older 3D games like RollerCoaster Tycoon 3, or even sometimes just watching YouTube videos at 1080p. Regardless, thermal performance under heavy load in laptop should either be tolerated, or the manufacturers should disable higher clock speeds. My W530 on the other hand has no issue with heat. Heavy gaming puts it to about 75-80C. It is also much bulkier in size. Edit: my dedicated graphics is off most of the time. Even then, CPU alone can drive the temperature up through the roof.
