    How do I know if my MacBook Pro is overheating due to bad applied cooling paste?

    I have no idea how hot it should be when running whatever programs.

    Right now it's looking like this:

    Currently running:
    Adium, one chat.
    Java application (Activity Monitor shows: 50% CPU, 34 threads, 636 'Real Mem'
    Firefox, 5 tabs open.

    It's using the intel graphics card right now.

    (And if I open it up to re-apply cooling paste, will it void the warranty/applecare?)

    Those temps are not even close to overheating. MBP's can run as hot as over 100 degrees celsius. You will know it is overheating when it shuts down. You are fine.

    It is at the manager's discretion on whether or not to void your warranty but most likely if they open it up and notice the thermal paste isn't spread on horribly like they do it, they will know you've been tinkering with it.

    As the guy above said, when it turns off. The CPU (and components in general) are designed so that when they reach a thermal roof they automatically shut the computer down to prevent damage to the components.

    And yes, they can run very hot.

    How will I know if I need to re-apply paste? In general, it seems to be rather hot :rolleyes:

    Well, I would be a bit nurvious if it goes past 95C under light to mid load. But under full load the 13" MBP doesn't go past 93C.

    I wouldn't worry about that. There are VERY few people who have had that problem. We know that Apple doesn't apply thermal paste in the best way but it shouldn't affect your computer.

    They are telling you the temps are fine, so why would you re-apply the paste? Seems crazy - you are just looking really hard to find something wrong.

    It'll shut down. Don't worry about the paste so much

    Listen to what everyone in this thread has said so far. Your temps are nowhere near the thermal limits of the board. Notebooks, especially Apple's, run hot. You're safe so just relax and enjoy your MBP.

    You can reapply thermal paste when you are out of warranty, if you must. My White MacBook 3,1 went out of warranty, and was idling around 65ºC. I decided to reapply thermal paste and it idles around 40ºC. That is what you are at, at partial load, so IMHO, you are fine.

    how do you have 16 cycles and 100% battery health. I lost battery health the first day I had the macbook.

    I did, the first day. It continued to go down after that, and continues to do so.

    Before I sold my 13 inch Alum MB I had 53 cycles and 96% health.

    Taylor then something is obviously wrong. I'm at 99% with 108 cycles on the latest MacBook Pro.

    Well its at 97 percent now, and has been for a few days. But I'm wondering what made it lose 3 percent capacity in so little time. I hope it stays here. I havent even used the battery much , hopefully it doesnt get worse when I do use battery.

    your computer is perfectly fine, those temps aren’t that hot at all.
    and, would you like to know how to take a screenshot of just one individual window?
    like this:

    Have you calibrated it recently, you may need to.

    Yup, calibrated it first thing after turning it on and system update. Calibrated it properly too.

    Is my MBP too hot?

    It is a Retina 13 with 8gb of ram and 2.4 core i5 processor.

    Sunny but Cold.. Canada
    It is a 'fine quality little sports car' and it will Run Hot, but as stated above, you are nowhere near there yet.. Obviously, the Ambient temperature you use it in will affect how HOT it seems as well, but anything under 80ºC is pretty tame and usually won't excite the fans much.. Likely..
