So, I took out the new cpu, and put back in the old cpu.
Fedora booted just fine - All is working  - but of course,
it still freezes or panics after a few minutes (2 - 5 minutes).

So, I contacted the Ebay seller 
<http://www.ebay.com/usr/rakicomputers?_trksid=p2047675.l2559>rakicomputers 
and reported the issue.
The seller first told me something wrong with my laptop.
So I replied that the old cpu still boots just fine - until it gets too hot
and the it freezes or crashes.
The seller did not respond.
"g" had replied once that I should find a reputable seller.
Well, this seller seemed to have a high rating on ebay.
S/he is a gold ribbon Top Rated Plus  seller, with 99.9% satisfaction.
