24" iMac temperature concerns...

I've had the new 24" iMac since last Thursday - absolutely fantastic computer, and I'm thrilled with it. Speed, screen size, everything is great, but I'm quite worried about the temperature of the thing.
It gets EXTREMELY hot, I mean, hot enough to feel from a normal seated range.
Should I be worried about this? I haven't had a new-ish Mac in ages, so I'm not sure if it's normal or not.
Has anyone else experienced this? Thanks all!

Hello everyone.
Sorry to Bump this post, but I just got a new 24" iMac after 6 months with a Intel 17" iMac that gave me no problems whatsoever..
I have read this thread attentively and followed instructions accordingly.. Using Temperature Monitor, my Smart Disk is always at 50-52ºC (~124 F) and my CPU Cores 1 and 2 from 44ºC to 60ºC (thats ~111 F to ~140 F)....
I came to seek help on this matter because the top part of my 24" iMac is very hot.. too hot to leave my hand there, even... and only after a few hours with the computer on; I run some applications like iTunes, iPhoto, Safari, Messenger (and Temperature Monitor) plus run World of Warcraft on window mode at 1900x1200. Now, I have done all this (and more, live video editing using iMovie) on my 17" Intel CoreDuo iMac for sometimes up to 8 / 10 hours a day and it never got hot enough to become a concern.
What is going on? According to some posts, the top left part of the iMac is the HD, while the lower part has the CPU Cores. My questions are these:
1. What is the normal temperature for the iMac 24" running apllications that are CPU intensive and GraphicsCard intensive?
2. When (in measurements) does Hot become Too Hot?
3. Having constant temperatures as follows, is it a sign of malfunction? Should I contact the store?
SMART Disk: 50-53.0º (~124 F)
CPU Core 1: 44-59.0º (~111 F to ~138 F)
CPU Core 2: 44-60.0º (~111 F to ~140 F)
And this only after say, 3 or 4 hours of activity..
Help

  • IMac i5 HDD temperature concerns

    I've been using my iMac for a week now, (hate to say this as to jinx), without issues. It's fantastic. I'm loving it. I have one concern. SMART results are flagging the temperature as a fail, with steady drive temps always around 50 - 52 degrees Celsius. Is this too hot for the drive? (I'm also running TechTools SMART Check, and am getting variations in the read error rate, seek error rate and hardware ECC recovered.) In my last iMac (2.4 20") these were always perfect...Or am I just being paranoid?

    This is not the first thread I've read about temps with the hardware in the new iMacs. Peoples concerns seem to be misplaced with no basis for comparison. In regards to this thread on the HD, according to the specs on Western Digitals website, (http://westerndigital.com/en/products/products.asp?driveid=733), normal operating temperature is 0C to 60C. If your temp is above 60C, then be concerned.
    Is this hard drive running hotter than the average temp of all other users in various machines, including non all-in-ones. Use Google and find a basis for comparison. My guess is it probably is and you should expect this with an all-in-one. If this bothers you, then you shouldn't buy cutting edge technology, (not talking about the hard drive, but the form factor of the machine), until user feedback can put your concerns at bay. Otherwise, if your HD is running under 60C, Apple seems to have responsibly provided a machine that meets the OEM's specs.

  • IMac temperature comparison

    I thought it would be a good idea to have a topic where we can compare iMac internal temperatures. I have not had any problems with mine and my temps usually stay pretty low but yesterday I was burning several dvds and watching a movie at the same time and all my temps jumped up quite a bit. I cannot tell if the fans are speeding up or not as they are always quiet. I'm a little concerned about my hard drive temp. It usually runs about 53-54C but it was at 57-58C all last night.

    Good reason to be concerned -- high temps seriously affect HD life & dependability,
    and that particular drive specs 60℃ ambient as its maximum operating temperature.
    Your "HD Bay 1" is running uncomfortably close to the limit.
    Here's what Bresink.com's +Hardware Monitor+ says for mine -- about the same

  • Tip:  Display brightness affects iMac temperature

    Not a question, just a useful tip for anyone concerned about the temperature of their iMac G5. The brightness of the LCD display can signnificantly affect temperatures inside the machine. So if you are reading high temperatures in your iMac, or the fans are running at higher speeds than you'd like, try going into System Preferences/Displays and adjusting the screen brightness down to the dimmest you can handle. It will take a while to take effect (as the machine needs to cool) but there will be a noticable difference over time.
    This may also reduce eye-fatigue (provided you don't set it too low.
    I was told by an Apple Tech that the reason for this is that the LCD is lit by powerful neon bulbs that output a lot of heat directly next to all of the other components in the machine, so dimming the brightness reduces this heat-output somewhat.

    I have to say, nice tip! I dimmed my iMac's brightness down to the lowest it would go. In about a minute the CPU temp dropped a good seven degrees Celsius.
    Now I'll test it at 50% brightness.

  • Worried about iMac temperature

    My iMac's CPU temperature monitor sometimes goes up to 175˚ Fahrenheit, and stays at 140˚ Fahrenheit constantly. I'm worried about it. What is the average temperature for an iMac? Should I be worried at these temps? Is it damaging to be at these levels for an extended period of time?
    Thanks for your help!
    EDIT: Oops! I put this in the wrong forum. Could a mod please move it? Sorry...

    Max, welcome to the discussions!
    Mine stays around 150-150F also, depending on what I am doing. I wouldn't be concerned about that, bit 175F is pretty warm. Forunately, your Mac should shut itself down before any damage occurs.
    You might want to open yours up and remove some dust and such it there is any around. Clear the vents also. Some people have reported that doing so has reduced their temps.

  • Temperature concerns(its very worrying)

    Hi, I have a IMac 9,1 on a intel core 2 duo.Here are the specs: Model Name: iMac
    Model Identifier: iMac9,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.66 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 6 MB
    Memory: 4 GB
    Bus Speed: 1.07 GHz
    Boot ROM Version: IM91.008D.B04
    SMC Version (system): 1.44f0
    Recently i have been running on bootcamp XP due to some software needs. And it has come to my attention that the Imac gets really really hot at the top left hand corner of the screen. SO now i have a few main concerns:
    1) Is it normal to have so much heat at the top-left hand corner? I'm in asia, so the temp could get quite high sometimes.
    2)Will it damage the hard drive or anything else due to the high amount of heat?
    3)WIll Apple warranty be void because I am running xp bootcamp?
    4)Is there anything i can do on xp to lower the heat?Increase fan speed?
    I would really appreciate any help on this matter, as this computer is of great importance to me & my work now. Thank you

    The GPU is high, and since Boot Camp is an Apple application, it certainly doesn't void your warranty.
    What is the ambient temperature of the room your computer is in?

  • Temperature Concerns on Power Mac G5 Dual 2.5

    After having my PowerMac G5 Dual 2.0 power supply burn up and take the rest of the computer with it I am concerned about my PowerMac G5 Dual 2.5. I am hoping someone out there can let me know if my values are normal or if I have reason to be concerned.
    Here are the stats on my Mac:
    Model Name: Power Mac G5
    Model Identifier: PowerMac7,3
    Processor Name: PowerPC G5 (3.0)
    Processor Speed: 2.5 GHz
    Number Of CPUs: 2
    I am using Temperature Monitor to determine the temp of my computer.
    Here are the results: Time Interval: 7 Days showing Minimum and Maximum Temps
    CPU A Temp - 55.1C/131.3F Min - 93.1C/199.5F Max
    CPU B Temp - 49.6C/121.4F Min - 80.4C/176.8F Max
    Main Logic Board Backside - 42.0C/107.6F Min - 50.8C/123.3F Max
    Memory Controller Heatsink - 62.6C/144.7F - 72.4C/162.3F Max
    Are these typical ranges for this machine? Looking at the history window the CPU spike occurred about 4 times over a 7 day period. For the most part it stayed under 70C.
    I have searched the internet and I can't seem to find out what the normal operating temperatures should be for this machine.
    Thank you in advance.

    I just reassembled my G5 (2004 2.5 GHz) cooling system last night and now appears to be working properly. Before the repair the fans were running full speed nearly 100% of the time - hardware tests indicated a temperature alarm condition for CPU A that prevented booting when hot. CPU A was typically running 10-15 ºC higher than CPU B. Other than the fan noise and booting problem the system was stable, never crashed. After disassembling the CPU's and heat sinks I believe the problem was the dried thermal grease between the CPU's and heat sink and/or the gunked-up copper fins of the heat sink. In addition, the o-rings had taken a set and the coolant had begun to seep out - no liquid, but visible residue around each of the heat sinks. I feel most, if not all, G5 water cooled systems (at least the 2.5 GHz models) will begin to exhibit these symptoms of failure.
    What surprised me most about the repair was how easy and inexpensive is was. After reassembly the CPU temperatures were about 1.5 ºC apart, averaging 50 ºC under a light load. Note, the CPU's will never operate at the same temperature since the heats sinks are plumbed in series.

  • Snow Leopard, iMac Temperature and Fans?

    Since getting my iMac eighteen months ago I have checked the temperatures regularly.
    Unfortunately I did not write them down and cannot remember what the highest "normal" temperature was, though the hottest place was always the "Power Supply Position 1".
    One thing I am certain of is that I thought the 3 fans just had one set speed because every time I checked the Optical Drive was always around 699rpm and the HD and CPU fans were always 1199rpm.
    Until a couple of weeks ago I had not updated the original OS which was 10.5.2, but then I updated to 10.5.8 in one go and last week I upgraded to Snow Leopard 10.6.1 by installing it over Leopard.
    Today I was doing some simple editing in Final Cut Pro for an hour and checked the temperature.
    The Power Supply Position 1 was 176 degrees F. I can't be sure but I have a feeling that I have never seen it above 169.
    I then put a 20 minute video in Compressor to encode and the temperature rose to a maximum of 179.6 and the CPU fan was around 1500rpm which I have never seen before.
    Has SL had any effect on temperatures or fan speeds?
    Are these figures normal?
    My room was only 66 degrees which is fairly cool.

    Thanks K T and Pondini.
    That's really what I was looking for Ikrupp, some figures from other users under moderately intensive operations (not writing emails!).
    Yesterday, when I had finished using Compressor the temperature started dropping from almost 180°F and when it reached 176°F the fan had also dropped to 1199rpm so it looks as though it doesn't speed up until the temperature exceeds 176°F.
    It appears that your figures are pretty close to mine. However, if others could give me figures they get under moderately intensive use, it would give me final confirmation that all is well (or not).

  • Another iMac Temperature thread

    iMac 24" 3.06Ghz C2D w/4GB Ram. This is not the machine in my sig.
    I've been getting hard freezes and difficulty starting up after these hard freezes. I'm starting to suspect temperature related issues.
    I get the freezes when pushing the machine hard with either Aperture or Photoshop. The machine will hard freeze. I'll reboot, it'll take longer to start up than normal (probably doing fsck or something like that) but then when it gets to the login screen I'll be able to move the cursor but not select anything.
    I'll play this game for about 5 minutes before it lets me back in. When it does finally let me back in the fans will start up at a high level, higher than they were before the crash and startup folly.
    Here is a screenshot of the temperature readouts from iStat menus. http://bit.ly/gipan5 These seem high to me and the upper left of the machine is too hot to touch. Apple has already replaced the logic board on this machine once for what seemed at the time to be a USB issue.
    Can anyone confirm that these temps are either high or within operating spec?
    Thanks!

    If those temp are Fahrenheit the are well within specifications. It would be useful to know how much RAM the machine has and how much of that is Free. It would also be useful to know the results of running Apple Hardware Test in extended mode.
    To get how much Free RAM it has please run Activity Monitor (Applications - Utilities - Activity Monitor) - click the *System Memory* tab and then let us know what values are in:
    Free
    Wired
    Active
    Inactive
    Used
    To run Apple Hardware Test in extended mode please click the link for instructions. If you get errors please post the error codes.

  • Imac temperature

    Hi. I have a 20" G5 iMac. It was just cleaned of dust and a complete system diagnostic showed no issues. The memory battery was replaced.
    It seems the reference for measuring internal temperatures is out to lunch. It shows 99 degrees f ambient temperature. I suspect that all the measured temps are high as well. The fans run audibly loud. The CPU fan runs about 3300 rpm. The air coming out of the unit is not very hot.
    Is there a way to adjust the reference?
    Thanks!

    I'm thinking "ambient" is a misnomer in iStat Pro. For a true ambient reading, iSP would require a remote sensor well away from the computer (a heat source). Same reason we don't install the household thermostat over the kitchen cooktop.
    After my G4 tower sleeps overnight, on morning wakeup, it is seldom at true ambient (room temp) because there are still low-level things happening inside that produce a little heat. The room is 75°F and the G4 is 84-88°F.
    Only if I turn the computer off and its stays off for several hours does the initial reading come close to room temps recorded by the workstation. Still a little higher because of the bypass in the power supply that maintains settings,
    I like iStatPro for other reasons. but having to invoke a Dashboard widget to check temps can raise them. Widgets are heavy hitters in Activity Monitor, especially those that have to "phone home" to work. When checking temps with a widget, you get "Heisenberged."
    I use Temperature Montor, also free, becasue it is a free-standing app and already part of the processor load when you look at temps. You can put the display in the menubar so checking temps requires looking up a few inches. No commnads required.
    http://bresink.com/osx/TemperatureMonitor.html
    I know of no way to recalibrate sensors, if they go bad they go dead, so I think you may be seeing the effect of a program trying to read something it can't.
    Get Temperature Monitor and see what it reports. I thikn it does a better job that iStatPro for temps.

  • Why does my iMac temperature go up when running games through Windows using BootCamp?

    Hey guys,
    These are my current specs: iMac 27 inch, intel i7 quad core 3.5 ghz, 16gb ram and 1tb sata hardrive with nvidia gtx 780m.
    Ive installed windows on my mac and have discovered that when running games the temperature is much higher. For the same game on Windows i've had my CPU run at 80-81 C on roughly all cores and my GPU temp went up to 85 C. On mavericks same game runs at temps of 58 C for CPU and 71 C for GPU. However on mavericks the frames rates are lower even when running same settings as on windows.
    I tend to think that mavericks is somehow limiting my hardware in order to keep the temperature down whereas on windows on my mac I can really feel the kick of the system yet the temperature goes really high. Is there any way to sort this out?

    gpu driver optimising is much more used in windows it give better fps but less stability and as you notice more heat and more noise as the fans work harder
    lower the eye candy and resolution is a cure

  • IMac temperatures

    Just wondering if this is a normal temp...
    I downloaded smc fan control and istat pro since I've noticed my upper left corner of my iMac was really hot. (I have the newest imac that was released in Nov 2011 running OSX 10.7.4)
    These are the temps I've been seeing with istat pro... (in celsius)
    HD mac : 50-55
    CPU : 47-56
    Ambient : 31-34
    GPU diode : 56-58
    GPU heat sink : 54-55
    Mem controler : 56-58
    Optical drive : 46-49
    Power supply 2 : 67-70
    Nothing to be worried about?
    At what temperatures should I start to worry or up the fans in SMC fan control? the temp i see on that right now is 48 with around 1400 rpm
    Thanks!

    Might try smcFan Control. In conjunction with that, I also have a fan blowing at the back of the computer to dissipate the heat from the aluminum back. But not much can be done when it's just a case of hot air being blown around. We've been having a bad heatwave here -- it's 30C inside right now -- and I just don't use the computer as often, allowing it to sleep frequently to cool off. HD  temps constantly in excess of 45C aren't that healthy. I don't let it stay in the upper 40s for long.
    If you use smcFan -- or even without -- you must pay attention to keeping the air intake grilles (there is one running along the bottom and one behind the stand) free of dust by periodic vacuuming,

  • How to check iMac temperature?

    What's an easy, free way to check the temperature of my late 2013 iMac? It's a 21.5 2.7ghz 8gb model with Mavericks. Also, what temperature is it supposed to be at?
    Thanks!

    iStatMenus is a really cool (pun intended) little app that will give you everything you need. There's a 14 day demo to test it out, that may give you the info you need, $16 if you want it longer. There's a bunch of sensors in your machine, the temperature each one is supposed to be varies but something in the 80-100° range is probably "normal" for most of them, but of course will change a little according to ambient temperature, and a lot depending on what you are asking your CPU & GPU to do.
    Get it from the developer here, install is quick and painless:

  • Definitive Intel-iMac Temperatures?

    I have searched the internet for official Apple figures on what temperatures are "normal" but have come up with nothing. It appears that Apple is very reticent about divulging statistics .... rather like Rolls Royce used to be many decades ago. Legend has it that when a prospective purchaser asked how many BHP the engine developed, they replied, "Enough"!
    There is just one part of my iMac that appears to me, to be reaching a very high temperature.
    Namely the "Power Supply Position 1" - whatever that may be. When my iMac is working moderately hard it reaches temperatures of 180°F.
    Now although this appears too high to me, it may be perfectly normal but I have no way of knowing this, as Apple has not published (to my knowledge) details of what constitute a safe range of temperatures.
    So has anyone got any definitive data?
    I would like to stress that all the other sensors record very low "safe-sounding" temperatures and I have also recently downloaded the SMCFanControl app.
    Is the temperature of the "Power Supply Position 1" critically important or could it happily soar to boiling point with no adverse effects on the computer?

    It sounds as though your high fan speeds might account for the low temperatures. My fans are at the default setting ...... Optical Drive = 700rpm and the other two at 1,200rpm.
    Only when the PS exceeds 176°F (approaching 80°C) does the CPU Fan speed rise to 1,500 when left to the Apple settings (before I got smcFanControl).
    As you can see from this screenshot, the PS temperature is tremendously ahead of the others.
    This is after about an hour of light use in a fairly cool room.

  • Imac temperatures ¿too high?

    Hi,
    I've owned my Imac G5 for about 6 months now, and the other day I had my hand placed on the top of the screen and I noticed it was quite hot for the normal. I live in Spain and its about 36º in the afternoon (96F), maybe its just the Imac facing the summer, I don't now. Anyway, I'll leave the stats of the temperatures from a widget I've got so you can know a little bit more, thanks
    [img=http://img61.imageshack.us/img61/3830/tempsan4.png]

    The information Chris CA gave you was absolutely accurate - if your computer gets too hot, the power supply unit will automatically shut it down when it exceeds the recommended temperature, so until that happens, you don't need to worry about it. And you are posting in the wrong place, this is for PPC iMacs, which have not been produced for several years. You have an intel and he gave you the correct forum to post in.
    His information was not only correct, but useful as well, if you trouble to read and understand it instead of being snarky!
