Much to my dismay this was not end of trouble.   

Last night I tested fan about questioned if it was operating.   

To my dismay, it operates last night in house and saw it working.

But after being outside, it said "nope.  Not gonna happen. " Thus, transmission started failing.     

Didn't realize it because the fan for power supply was on.  I literally had to look at back of machine to verify.

I am currently waiting for fan from Amazon tomorrow and will install.   Unfortunately, the required fan is 80 mm and best buy only carries 120mm for today's computers. .

No fun for me today.  Was looking forward to the contest later today on digital.
