Hi I'm driving from New York to Pennsylvania with my newly built PC. I have a coolermaster hyper 212 heat sink installed so I was a bit nervous of vibration causing it become loose and damage other components. That being said I do not want to remove and have to reapply the thermal paste and everything so I decided that i will secure it by placing some sort of packing inside the case surrounding it to keep it snug and secure. My question is what sort of packing material would be safe for that? The only idea i've had so far is newspaper (a lot) crumpled into balls surrounding it to keep it secure. Would newspaper be safe? Is there another way that's better (and easily accessible)?
