I bought a new Macbook Pro 13" and the CPU and motherboard temp seem great, in fact, I can't get them above 10c. But the disk temperature is ludicrous. It gets up to 45c (112f) JUST watching a youtube video. I won't say it burns me, but it is absolutely uncomfortably hot, and even makes my workspace warm. I don't think my previous mac, the 2013 air, ever got this hot, but I never noticed. I've definitely noticed the temperature with the MBP, and am considering returning it. Anyone else noticed this with the new model?
