You may want to review your thermal paste job and the specs sheet of the paste. Some paste is conductive so if you are a bit messy (getting it on the pins & logic board) you can create issues.
I would fully clean the board making sure not to get any onto the logic board (wipe off fully, then wash the area down with an oilless spray contact cleaner (test it first, spraying on a sheet of glass - If it leaves a film don't use it!). I use reagent grade 90% isopropyl alcohol in a pump bottle so I know its clean.
Then redo your paste job it doesn't take much! Then lets see where we are.
