    I just noticed how my GPU gets really warm when not doing anything. Right now just using it to watch Youtube it is at 70C while my GPU diode is at 77C. The area above the keyboard is extremely warm and I just wanted to know anyones opinion on if it is normal. It is not currently plugged in and is on a stand that does not cover the full area of the laptop. It is a refurbished 2013 i7/16gb/512SSD/750m

    On a side note. Are there any drawbacks to running my fans at 100% all the time besides the noise? I don't want to be pushing them hard enough to have them die on me next month.

    "Just watching you tube" is not the simple thing you think it is, if you are using chrome it is poorly coded for macs and a resource hog, if you are using flash this is as bad as chrome, stick the 2 together and it'll heat up your computer no end, lower your battery life and generally use resources. Use safari and use click to flash to keep your resource hogging down.

    Your temps are well within spec and not worth worrying no about so unless you can't use the computer because of heat then accept the warmth that comes with a metal case and know that it is running as it should do.

    Thanks. I always knew it ran warm. I am just not in a situation where if it breaks due to heat I can afford another one so I just want to be extra cautious. Are there any drawbacks to running my fan on 100% for the majority of use besides the noise?

    It's not the best for the fans, but they are designed to be on high and it will probably affect their battery life incredibly insignificantly.

    Another direction to consider - your MacBookPro case is made of aluminum, which is a very effective heat conductor. If you feel heat on the outside of the case - areas of the bottom, around the keyboard area - that's a good thing, and tells you that the more heat you feel on the outside, that heat is being drawn out of the heat-producting parts, cooling the whole system more effectively. Your entire Mac is a pretty effective heat sink. One of the "drawbacks" is that you will feel hot spots on the outside - because it all works.
    If you want to monitor the temps that are produced, and control your fans as you wish, then there's several solutions that allow that.
    The important issue, I think, is to be aware of what really is a high temp on your Mac, and if your fans run wild when not needed.
    I don't believe that you should have to live with fan noise, unless it is necessary.

    Those temps are normal and nothing to worry about. Don't bother messing with your fans, Apple's engineers know their stuff better than you do, let the machine take care of itself.
