I just got all the parts for my new PC (A Ryzen 7 3700x, Strix x570-E motherboard etc.). Unfortunately as I was inspecting the stock cooler, I scuffed away some of the pre-applied paste. I then decided, for some reason, to just apply new thermal paste, so I wiped away the remaining paste. But now, the thermal paste I ordered is stuck in shipping and will take at least a week to reach me.
So my question is: Can I just put together all the parts for 5 minutes, just to see if the build passes POST. I don't plan to install anything etc. Is this dangerous, and will it void my warrantee?
