Lenovo T420s are known for overheating a lot.
I have top configuration: i7 2640M and nVidia NVS4200M and it easily reach 99+ C.
The best overheating solution is to replace thermal paste under heatsink on CPU and graphic card. In this video, i will show you how to replace thermal paste (how to remove heatsink fan) on Lenovo Thinkpad T420s . With new thermal paste, my laptop now reaches max temp 91C
