I think the grizzly frame is just picky about exact amount of force, probably why you are having memory issues.
Maybe try stock frame to see if stability returns.

Also delid may get 3-5c, probably not worth it.

Does the liquid metal stay in place between the CPU and the heatsink, there's no leak down?

If you 'painted' it on both surfaces, heatsink and cpu, it should stay bonded together. But there's always a slim chance it can slowly leak down over time.

Always a good idea to apply kapton tape or something as a barrier just in case it were do go somewhere it shouldn't.
