    Hey,

    I purchased the 15-inch Retina Macbook Pro a month ago and the computer gets really hot most of the time. When browsing Safari or watching a non-hd movie the temperature stays at 70-85 celsius. Today I decided to run the geekbench and during the test my computer had a constant temperature of 95 celcius. Is this normal or does the rMBP got heat-problems? I'm really worried because this computer cost a fortune where I live.

    Happy holidays!:apple:

    Hmmm.. 70-85when browsing seems a little high, but youtube videos can make your temp ramp up to around those temps. Does your fans kick in? Mine gets hot when watching youtube videos, just never so hot that the fans have kicked in.

    I haven't tried geekbench on mine, so temps when running it i can't help you with.

    The rMBP does get quite hot from time to time, but it's also fairly good at keeping it's temperatures at bay with it's cooling. It has never overheated on me, even during the heaviest of tasks. I wouldn't worry to much about it unless it gets so hot that the fans kick in during video-watching and whatnot :)

    When does it counts as "the fans kicking in"?

    While browsing safari/youtube they run at about 2000 rpm, (left 2000 and right 2200).

    The fans start to spin up when the CPU temp hits 90c on the rMBP (at least on mine they do)

    It's quite normal. Your rMBP is fine. 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. They won't necessarily spin faster immediately if temps climb, and they may spin up at different temp levels. Your Mac will monitor temps and adjust fan speeds as necessary, with no need for user interference or 3rd party apps.

    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.
