"Why is my computer making clicking/ticking noises?"に関する回答After saying I’m also having this issue, I figured it out. Your GPU is overheating. The heat sync inside only covers the CPU, so your GPU is exposed and basically on its own. My advice is to download Mac Fan Control, then set the censor to your GPU, and set the threshold for about 72 C. I’m actually considering modifying the casing to allow fresh air in. That’s the main design flaw with these models.
