Ok so I'm finally gonna build my first build after selling my PC. The CPU has been sitting here for nearly a year. Without me know that it had preapplied thermal paste, I often just opened the CPU and took out the fan just to look at it along with the CPU itself. I did close it back fully everytime i took it out. I did this about 3 times through the year waiting to finally build my PC. My worry is that the thermal paste went to "waste" all that time it's been sitting there. Should I just use it or remove it and apply the thermal paste I bought or will that pre app thermal paste be good enough?
