    Check this out, this is my laptop. I have told Apple about the issue and they blow it off, it has been going on for quite some time. I've continued to record the temp of the charging port. It gets so hot that it will burn your skin if you touch it for more then a second.

    Just thought I'd share. Be careful out there, you might come home to your laptop having caught fire and your house gone.

    Your MacBook is NOT overheating. It is quite normal for Macs to get hot during intensive operations, and it is also normal for the power adapter and the charging port to get very hot while charging. It is not a fire hazard, nor is it dangerous.

    Apple Portables: Operating temperature
    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. (Source: Intel)

    If you're not already using it, iStat Pro (free) or iStat Menus ($16) will give you accurate readings of your temps and fan speeds, among other things.

    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.

    Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). iMacs have 3 fans with minimum speeds in the 800-1200 range. 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 a slot on the back near the top of the computer. Make sure the vents remain unblocked to allow your computer to perform at its best.

    It isn't overheating and that is very normal. It won't burn your skin. Have you ever left your hand on there long enough to cause a burn? No, because it won't be able to burn your skin. My 2007 Blackbook does get very hot when I have it doing things, but do I worry about the heat? Not a bit because I know it is normal and I'd rather have a hot Macbook than a dead one whose death was caused by a poorly designed cooling system like my cousin's 2007 HP laptop.

    170°F is a fire hazard? :eek: Unless its in °C you don't have anything to worry about ;)

    Besides, shouldn't that macbook be using the old style T-connector? Might be the issue right there.

    72'c won't burn you unless you hold soft skin on there for a period of time!

    I see your not using the original MagSafe did you get a higher wattage adaptor when you changed it?

    Firstly, where are you using your MacBook that 70℃ is a fire hazard?

    Secondly, it doesn’t seem beyond the realm of possibility that an orange LED could be emitting infra-red, giving a false reading. You should be using a contact-thermometer for something like this.

    Thirdly, that is the wrong charger for your MacBook. There shouldn’t be any problems using it, but those models came with a plastic T connector rather than the aluminium L connector you are using.

    Still, couldn’t hurt to take it into an Apple store along with your charger and see what they have to say about it.
