I have this problem in my 2011 27” - that the seconday heat sink to the power supply is running 20˚C hotter than the primary and the proximity sensor, and even with specific and detailed control of the air flow with TG Pro is very hard to cool. WHY this specific heatsink’s higher temperature? [br]

And where is it? I have not been able to locate its position? Since it’s to do with transporting heat away from the power supply, it probably has nothing to do with cooling paste?
