I searched around online and in this forum but haven't really confirmed or denied any of my doubts. I know the phrase "I'm worried my laptop is overheating" comes up a lot and I've crossed out the usual suspects. The laptop is 4 days old and has no dust or anything blocking the fan/intakes. I have a mid 2014 macbook pro: Relevant Specs:
I7-4870HQ at 2.5 GHz
GT 750m
I've noticed that the core voltage is consistently at 1.8 V and goes even higher under load. The temps are around 60-70 watching youtube, but can get up to 99 under load (Cinebench, CPU) at which point I decide not to try pushing it further. Strange thing is that when stressing the GPU using cinebench (which has a higher TDP than the CPU (50W vs 47W), the temps stay around 80.This seems to happen regardless of ambient temps ( only change by a few degrees depending on surroundings). I've checked for background processes hogging the cpu and I've also tried resetting the system management controller. The fans stay around 2000RPM which is a third of the 6000RPM they can go up to. I had to manually push the fans during the stress test to prevent the temp from going above 100C.
My question is are these voltages/temps normal for a macbook pro and are they safe? Is it safe to try to stress both CPU and GPU at the same time without killing it? And how would this impact the longevity of the laptop? I know ultrabooks with high performance specs usually get hot, but how hot is too hot? Should I replace the thermal paste or just get the laptop exchanged?
