    I have the fully spec'd out 2015 core i7 5557U 3.1ghz version. It runs very warm, uncomfortably so. My palms are sweating constantly.

    I also have the older late 2013 Macbook Pro. This time only the core i5 2.4ghz. It runs much cooler.

    Does anyone else have the issue?

    I'm especially interested in those that have the 2015 core i5 2.7ghz processor. Does that run cold? I am thinking of swapping mine to it

    I have the i7-5557U 3.1GHz 13" rMBP, with 16GB RAM and 512GB SSD. It idles at around 47-55ºC, and it's pretty cool throughout.

    Are you using Chrome? It's a resource hog.

    Thanks, I am not using Chrome. That was the first thing i stopped using. I use Safari only.

    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:

    I have the base model of 2.9 GHz i5 rMBP 13" 2015 model and don't have this issue when using it and always keeps cool, and no fan issues.
