As the title says, the temps of my brand new 3 plus were bad, really bad, it went from 40 to 100 C in a blink of an eye during any benchmark, or to 90 during simple internet browsing.
After opening it for the modding (i already had in mind to do so) i discovered that there were no thermal pads at all, the core-M was simply leaning against the copper heatsink, keep this in mind if you plan to buy one.
After the mod+undervolting temps during a stress benchmark are around 70-72 and the system enters power limit throttling way before going into thermal throttling.
I always wondered why use thermal pads between the processor and copper heatsink. Would it not make a lot more sense instead of replacing the pads with, also copper, shimmies to just make sure the copper heatsink directly touches the processor and then use heat transfering paste instead?
