After I cleaned my CPU with arcticlean nr1 (http://www.arcticsilver.com/arcticlean.htm)
I noticed strange round spots in those places:

. They disappear when it's getting dry. Is it coming form fabrication process?
 

Eureka!

Sounds like the moisture from the cleaner pooling on uneven surfaces. The IHS of your CPU isn't perfectly flat.

I've noticed that to on every Intel CPU I clean with the two step Arcticlean. It goes away after using the #2 part. I bet Intel uses an automated suction cup device to place or move the CPu's around and what we see is the residue left behind by 4 small suction cups.
