I'm in the process of building my pc, and right now my motherboard, psu, and cpu is sitting in the open air on a wood table and has been for the past day. I already applied thermal paste but not the heat sink, and I'm wondering if the thermal paste will dry up to the point where it is no longer effective. Should I be worried about this? And is it okay to leave these components in the open like they have been? One other thing, is it okay to have my laptop running right beside my motherboard, or will some type of electrical interference damage it?
