I don't think thermal paste is the problem here, the whole box is god damn hot, so it conducts heat well. At wall it measures 14-15w consumption, got it there from like 20-22w that was on defaults. Given that N150 is 6W TDP, the whole system just runs hot.
A fan would help, but I wanted fanless for a reason.
It does, sometimes.. but it is not a huge PITA.
I need to see if FairScan would do a better job.
