Stock AMD cpu thermal grease replacement if touched

I barely touched the stenciled thermal grease on a stock heatsink for an A8 AMD processor. Though the grease is still there, there is a slight outline of my fingerprint. Will this hurt the cooling of the processor since the grease was so thin to begin with? If so, can I just add a bead of additional grease on top without completely removing the old grease first?
Thanks in advance!!

If you just barely touched it on the edge i've done that before and you will be fine. If you have a good fingerprint in the middle I would replace it.

The fingerprint is a little toward the middle of the pad area. Do you think it is OK to just add a really tiny bead of additional grease without completely replacing the original? Would this increase the risk of getting an air pocket between the two?

No do not add any grease to it you will have way way too much grease then. If you want just start it up and see what the temps are if they are good don't worry about it. If they aren't take it off clean it(rubbing alcohol and coffee filter) and put a dot the size of a grain of rice in the middle of the CPU and remount.

OK, I definitely don't want to over grease it. The print is straight down and back up (with little pressure) and no smearing so I will try as is per your response. I'll keep an eye on the temperature and see how it goes. Any idea of the optimal temp range? I don't see any specs on it.

Sounds like a plan. and usually 30C idle 60-70C load
