Hi! I've got A1398 Late 2013, I7 4960HQ and discrete GPU. It's overheating and can't boost higher than 2.8ghz despite it should go up to about 3.4. It overheats, despite the fresh thermal paste. I even changed the heatsink and it caused NO CHANGES. Here are the temps (with old heatsink). 1. Before CB 2. While second run launched instantly after the first Now after I installed the new one It's even worse for some reason, idle cpu is about 65, CPU PCIE Proximity is 70 constantly! Airflow 38 in the same time. What the heck is that?? Thermal paste is Cooler master V1 IC value. I apply it a proper amount, I screw it properly, no way I could screw it up. I found some similar things in one place only, but there's no solution fixing-a-boiling-hot-macbook-retina-2015 Can anybody suggest me what could it be please?
