Oh if you insist...

#1 indication of cluelessness: Doesn't realise there's a difference between the process size of the chip and the positioning of chips on the boards. "Derp, joo can't place duh 28nm chips like der 130nm chips because dose are obsolescent"

#2 indication of cluelessness: Doesn't realise there's a difference between the thermal problems of a ~200W chip and a ~400W chip "Derp, KNC can use a air cooled heatsink on a ~200W Chip so doing it with der 400W must be real easy too"

#3 indication of cluelessness: Doesn't realise that heat will have to be distributed and spread 3 dimensionally out of a 2 dimensional area, and the difference between 1 square inch and 4 half inch squares is that they basically lose half their conduction path each when butted together. "Derp, that should oughta be okay, I mount my CPU sinks with der CPU right in one corner because dey work just as well like dat"
