I have a thinkpad x220t, and it has the i7 2620m. I have been searching for a pretty long time on how to undervolt it and it seems impossible. It goes upwards of 90 degrees even with thermal grizzly and i clean it regularly. Any suggestions to cool it down other than a cooling pad which i plan on getting? Also, instead of going to 3.4 ghz, it stays at 3.2, is this a known problem? And if anyone knows, how can I over or under clock my graphics? I know this is a lot but please help

You change the max frequency on your power plan to limit it and have the voltage auto adjust. It won't be a true undervolt on the cpu, but it can reduce Temps.
