OK so I unmounted my heat sink from the cpu...it had thermal compound on it. I was curious if i need to replace it...I know you need to if it is a pad, i do have some artic silver handy...so I am just curious.
You don't have to...but it's best to. Just clean the CPU and Heatsink and then reapply some AS5...so you pretty much just have to clean and follow instructions.
