    I got my macbook pro retina when it came out. I've noticed that its been much hotter than my previous mbp. Just with normal internet use and spotify, it gets to temps of like 60 to 70 degrees celsius. It once wet up to over 100degrees but that is much more rare. I brought it into the :apple: store and they said that a manager can make the decision to replace it. Do you think I can get it replaced or is it within normal use temperature?

    Also, they ran the diagnostics tests at the :apple: store and said the fans were working properly. Could there be another reason for the heat?

    Your input would be much appreciated

    Thanks in advance

    Those temperatures are well within normal ranges.

    Sensor arrangement is different under Ivy Bridge, most likely you rMBP is actually running cooler than the previous MBP, mine does and i still have the Late 2011 15" for direct comparison. For a Retina the temp is fine don't worry about it.

    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.

    Same thing happens to me sometimes. Everyone tells me don't worry.

    People need to stop talking about TJMax or acceptable temperature.

    First, it throttle when temperature goes up.

    Second, it burns your fingers when you click on the keyboard, it's painfully bad to touch unless you are really used to it. (on lap is even worse)

    If it can't throttle itself anymore or the cooling is so inadequate, it will turn itself off to prevent damage. This rarely happens to properly working Macs.

    Human skin starts to burn between 130F and 140F. No external part of the Macbook gets this hot. It may cause discomfort, but it will not burn the skin.

    Then try some of these suggestions they do work: If you are concerned about temperature and want to reduce it elevation of the rear of the machine helps, as sitting flat on the desk only reflects the heat back to the base of the Mac. You can buy passive aluminium coolers like Rain Designs Mstand or iLap. Most powered coolers are designed for PC notebooks and don't work overly well with Mac`s if at all. One cooler that does work efficiently is the Moshi Zefyr 2, as it`s principle of cooling is specifically designed for Apple portables, by blowing the air horizontally across the base of the computer, however don't expect miracles.

    A cheap USB fan can achieve the same if strategically placed, not as elegant mind, nor as easy to put in your notebooks case :p but they do help to reduce case temperatures.

    You can use software to override Apple`s own cooling algorithm by manually taking control of fan RPM and setting up power profile presets with SMC Fan Control 2.4, or here with UltraFan which allows you stipulate a preset temperature and the software will automatically raise and lower fan RPM`s to keep the system at the predefined temp, which i personally feel is a far more elegant solution. At the end of the day you want to control your system temperature, not your fan rpm`s. For me SMC is now pretty much redundant with the latest release of UltraFan having manual control of the fans RPM, and subsequently i am starting to uninstall it from my own Mac`s. SMC FC is a great app, however although it`s recently updated, functionality is limited compared to some newer apps, equally SMC Fan Control is rock steady stable and a finished product.

    Strictly speaking Apple`s own cooling algorithm works, albeit at sacrifice of increased temps for quieter operation. This has always been the Apple way and is really nothing detrimental to the system, i have one MBP from 2008 all original barring a recent fan change that has an uptime of over 30K hours. The latest MBP`s need less assistance in remaining cool; for some it`s simply disconcerting the heat generated and transferred to the case, although it`s perfectly normal as the aluminium acts as a heat-sync. i have to deal with elevated ambient temperature so at times a software solution is useful. Apart from the passive cooling the Mstands bring they also offer a very sound ergonomic solution. A passive cooler and UltraFan will maximise the cooling, there is little else you can do short of reducing the ambient temperature or the system load. If I know i am going to push a system i will close all apps that are not essential as this can and does make an impact to system temperature.

    High temperatures in general is not overly harmful to your systems, what is far more detrimental is thermal stress, where temperatures rapidly fluctuate by significant margins over a short period of time. Anyone striving for great longevity should look to minimise rapid temperature changes, here UltraFan is your best friend.

    Using a RainDesign Mstand, a Moshi Zefyr 2 and latest version of UltraFan I can reduce temperature by over 20C when transcoding an MKV video file, and that is something worth thinking about;

    • Apple default cooling algorithm 99C - 103C (still on Mstand) fans 4K and escalating :eek:
    • Mstand, Zefyr & UltraFan 79C - 82C fans at 5.8K :cool:

    The old adage still applies; it`s easier to keep a system cool, than cool-down an already hot machine. This being said it`s not strictly necessary, equally it`s nice to know that there are options for reducing temperature out there.

    Hmmm.. mine never exceeds 70 Degrees C, no matter what I do !!! That's the highest I've ever seen it go...Normally hovers around 33 - 38* C, even with multiple tabs open, outlook, msn messenger, and spotify running. My 2011 15", however, ticks the 85 degree C scale pretty fast, especially on bootcamp or while doing any Video Conversion or graphics intensive work.

    I don't think I've ever seen it go 100 degrees or higher though. But, that may well depend on the load on the system and the type of work you do... Like others have mentioned, it is within normal operating range so you should be fine, but even at 80 degrees C, it gets a bit un-comfy to use as a laptop!

    Use Activity Monitor , sort by CPU% ..you should not be getting 60-70 for just doing what you state you're doing ...during normal browsing with 10 or so open tabs, and a few other things, my Retina stays between 40 - 45 .. it will occassionally hit 70 -80 if I'm doing something that's processor intensive, but it quickly cools back down to the 40-45 degree range when those tasks complete .. .. You can also try smcFanControl app

    TJmax is the temp at which your Mac will shut down to prevent damage, so that's helpful to know. It will throttle CPU about 5 degrees before TJmax, so again it's helpful to know what it is. To stop talking about it or ignore the facts isn't an intelligent way to address the issue.
    As already stated, it's quite normal for the keyboard to get very hot during intensive operations such as gaming.

    The throttling does not start 5c before DJMax, it happens around 75c.

    It's normal for gaming, but any other operation like Video chat, Youtube, Netflix, or any other casual activity will heat it up still. it's very unpleasant to put on lap and use it. Not many other laptop have this problem AFAIK.

    That is false. Throttling only occurs within about 5C of Tjunction Max, and may be only a degree or two. It certainly doesn't start as low as 75C.

    That throttling is by CPU design and safety purpose. The throttling I am talking about is the Apple's own throttling.

    I think the Nvidia chip throttles at ~75C (although Nvidia Turbo Boost will let it exceed that for a few seconds). Maybe Apple is being a bit conservative after getting bit by 8800MGT fiasco :)

    At least this is the phenomenon I experience when looking at MSI Afterburner in bootcamp. The CPU I've noticed in Mac OS X via MenuMeters and CoreTemp in Bootcamp will expectedly throttle itself when it goes to 105C.

    Apple doesn't do CPU throttling. The throttling is built into the Intel chips.

    You sure?

    Easiest way to find this out is to do in bootcamp.

    Turn on CPU-Z and Core Temp, then turn on any game. You will notice originally it was running around 2.3Ghz, then turn all the way down to around 800Mhz right when the temperature reach around 75c.

    The same problem was also reported by AnandTech with their MBP reviews.
