Hello, I'm building a new PC, and the only components I have so far are the CPU and GPU. I opened my AMD Ryzen 5 5600x box because I wanted to verify the state of the CPU and Cooler and I took them out of the box, both seem fine. However, I can see the Stock CPU Cooler has pre applied thermal paste... Is it ok if I just leave the stock cooler in my building bench/open air? Can Air/Oxygen alter the state of pre applied thermal paste when it's out of the box? I'll recieve the rest of the parts next week.
