Thanks everyone for your help!
I cleaned the heck out of the stock heatsink with Goof Off followed by 91% isopropyl
The cpu cleaned up easily with the Goof off followed by 91% isopropyl (using coffee filters)
Followed the Artic silver 5 instructions about tinting the heat sink. Added a thin stripe according to instructions for i3 cpus.
When reattaching the heatsink I realized I had turned the plastic screws the first time I installed it instead of just pushing them down.
Ran two stress tests using Real Temp and Prime 95.
at 100% cpu highest temp was 57 C. Idle temp around 27 - 30 C.
Good stuff! and a very common mistake regarding the pushpins.
