    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?

    There is nothing wrong with your MBP. Your temps are quite normal, and well within the safe operating range.

    If you're not already doing so, use iStat Pro (free) or iStat Menus ($16) to get accurate readings of your temps, fan speeds, etc., rather than relying on your sense of touch or sound. A forum member has posted a copy of iStat Pro that has been "tweaked" to enhance compatibility with recent OS X versions. You can download it here.
    The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat. CPU Tjmax = 105C (221F), GPU Tjmax = 100C (212F) on i3, i5, i7 processors. (GPU Tjmax may vary with specific models.)(Source: Intel)
    Unless there is a rare defect in a Mac, most temps are well within the normal operating range, considering the workload being put on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.
    It is also quite normal for your Mac to become extremely hot to the touch during intensive operations. The aluminum body transfers heat more effectively than other materials used in computer casings, so you will feel the heat more. This doesn't indicate that it's overheating and will not harm the computer to be hot to the touch.
    The fans in Macs are always on when the Mac is on, spinning at a minimum speed which varies by Mac model. They will spin faster as needed to keep temps at a safe level. If your fans are spinning up without increased heat, try resetting the SMC. (PRAM/NVRAM has nothing to do with these issues, so resetting it will not help.)
    The intake and exhaust vents are in the back of the computer near the hinge on all Mac notebooks (except the new MBP with retina display, which has intake vents along the sides at the bottom). The iMac vent is on the back of the computer. Make sure the vents remain unblocked to allow your computer to perform at its best. For Flash-related issues:

    Thanks for the scripted response, but 45c, according to their own specification is NOT normal:

    "Operating temperature: 50° to 95° F (10° to 35° C)"

    Anyone actually have a new MBP that can post their SSD temps?

    That's the temperature of the environment, not the temperature of the semiconductor. The SSD/HDD temperatures are not as important as you think.

    That "scripted response" was carefully composed after answering hundreds, if not thousands of questions like yours. It absolutely is applicable. The "Operating temperature" is the ambient room temp, not the temp of the components inside your Mac, which are quite normal.
