Are you guys UNDERVOLTING your CPU??? ⚡

So i have been unvervolting my cpu for about 2months now, using the LenovoLegionToolkit utility.

Have you guys faced any issues due to this or have any advice.

I spent about 3hrs to get to optimal power for my laptop at 22W. Lost only 10-15fps at 2560x1600 but my temps improved a ton, nearly 10 degree difference, from 95-99 to 80-85 full load. Also consumes less power.
