Yeah, I watch his stuff already. He specifically mentions because GPUs are large hot dies. I'd never use Kryonaut on a GPU (I've had very good luck with MX4 on GPUs Ive had to repaste or replace stock coolers on).

Bare die CPUs (laptops, delidded CPUs, etc) don't seem to be big enough to cause issues. I imagine, if I have to repaste the laptop, if it even lives that long (it is from 2012 as it is), it's going to be another 4 years down the road.
