BTW, can I rub the backside of CPU with eraser?

 

[scout_03]

no you could not use eraser and does cpu work good with the broken pin .

Still working, but will it cause the performance to drop?

Looks fine. I don't see anything darkened there.
You can try with eraser, just don't touch elements in the center of the cpu. If you break them off, your cpu is useless.

And if your cpu is working fine, then there's no need to do any of this.

I really don't see much of anything.

...and I have installed CPUs that have looked much worse than that.

It's working fine. Isn't it?
Then forget about those spots. There's nothing to be obsessed about.
