    I have to admit, as a PC builder I have recently purchased Mac's (for my business, an '08 Mac Pro and now iMac) I like the build quality and this iMac is fantastic!

    I'm installing Vista Business on it tonight as well. I'll post more later.

    Ok, did Apple use any fans in these things? This thing get so hot I could warm a coffee mug on it, this is nuts!

    I like the machine but this heat is insane, I called Apple and they claim "running warm is normal". Warm? Yeah ok then...

    Installing Vista, Aero will get this sucker warmed up I bet, if it runs any hotter I doubt I'm keeping it. I'll bring it upstairs later and let it run over night if it's so hot you can't touch the top then it's going back, no way it goes long term without something taking a crap.

    Anybody else seeing not warm but hot temps coming off of their iMac? I have a new 24" 2.8ghz machine with 4gigs of memory.

    What does iStat pro say your temperatures are? (Or did you wipe os x and only have windows on it?)

    As akm3 said, post some iStatPro temps.

    The iMac does run pretty warm. The case is made to extract heat away from the internals, to keep the amount of needed fans low.

    Congrats on your purchase.

    I've used macs for a long time now, and they usually get a little warm.

    Especially with the iMac, putting all those components into that slim case, you can expect there'll be heat.

    download iStat pro and see what the temps are. If they are not over the chart, and within spec, then you can rest easy. As long as that thing doesn't blow up :)

    The iMac should be warm to the touch but by no means uncomfortable. Post some iStat temperatures.

    You think it'll get hot running Aero? Try running handbrake... :p

    I would be interested in seeing actual temps though.

    Sorry for the delayed response. I loaded iStat Pro but I'm in Vista rght now. I've been gone all day and am heading to bed now, I'll log into Leopard tomorrow and post temps. Thanks for the responses.

    Due to rumors even if the heat isn't an issue I may take this back next week before the 14 days are up and hold off buying until either they see a price reduction or new ones are released. :apple:

    These things run hot because Apple designed them thin and to be as quiet as possible so, they use heatsinks to pull the heat out and distribute it into the chassis. There is really no danger to the computer itself however.

    Ok, not to be rude, running hot for any electronics hurts long term. Many people keep a computer for only a few years and Apple knows this so isn't worried about long term I'm sure. There is no excuse for a computer to run this hot, if it's a part of the design, I'll do without and take it back.

    I have an HP HDX Dragon 20" laptop with the 2.8ghz extreme cpu and loaded to the gills with 2 7200rpm hard drives and maxed out memory and video, it runs mildly warm at full tilt usage with very little fan noise.

    The iMac while doing no real work runs very hot, not warm, hot. I'm going to post temps tonight but I would not be shocked to see many sensors at over 120f, I'm not going to assume so I'll post the temps when I'm on the machine tonight.

    I agree. There are so many people that are concerned with the temperature that it is running at. I hear of people changing the fan speeds and other stuff. I've had mine for almost a year and I've never checked the temperature. I'm constantly doing processor-intensive tasks and yes, it does get warm, but that's how it was designed.

    I'm only using FireFox on my MBP and my CPU is at 55C and my GPU is at 52C. The general rule is, as long as it's under 70C you are fine.

    Only thing I would be worried about would be the HDD and PSU in the long term.

    Dude not to be rude at all, but you said your a long time PC builder right? Yes parts are parts but the Apple design and intergration is far better than ANY PC system for one. Ive been using mine for 2 1/2 years straight on 24 hours a day playing advanced games, and running Vista as well (For the record the machine gets warmer with VISTA running, its not Apples fault that VISTA's OS is coded like crap!)

    Ive not heard of many people complaining that their Imacs Burnt from heat issues in my time of reading and owning an iMac.

    If you feel its a BAD system replace it and try another one, Yes it gets warm, but I will settle for a little WARM monitor (Not that I ever need to touch it!!!) over the loud fans any PC has...

    Behind the lens
    My brand new 3 day old 24" iMac, with the 8800, running CoD4 for a good couple of hours, while torrenting and listening to itunes...

    Never goes above 130F, I was amazed (compared to my CD Blackbook which goes above 140F all the time just surfing).

    And the metal of the computer body gets warm, but perhaps your definition of "hot" is different than mine.

    Still, everyone is waiting for some temp specs... :rolleyes:

    I just got a 20" iMac a few weeks ago and I have experienced no problems with it at all. While it's running, it's a little warm, like any computer, but it never gets uncomfortably hot...

    Ok clearly the iMac design is very nice, I wouldn't have bought one if it wasn't but please don't give me the fanboy line of better than ANY PC system because that line is cheesy and simply isn't true. Your opinion may be that it is, but that doesn't make it fact.

    There is a reason why it gets hotter when running Vista, being coded like crap isn't it, but it's one that people use out of ignorance. Do you bow to the TV when the PC vs Mac ads play? I've run all of my Vista machines (thats 20 at work and 5 at home) since the betas and have had no issues. All OS's have bugs and Leopard is FAR from the perfection Apple and it's fanboys who drink their koolaid brag it to be. Vista is a victim of press, idiots and poor marketing and is also far from perfect, but it's the best OS they have ever made and SP1 helps in a big way. I think Windows 7 will be even better, I also think Snow Leopard will be something better as well, each has it's pro's and con's and neither is better than the other, but Apple sure loves that you buy it hook line and sinker.

    I went out to dinner with friends and one of the guys asked me if I ran Vista. I responded yes, in every work machine and home machine. His response "OmiGod how could you run that crap?" I calmly asked how much he has worked with it, his response, never but Apple says its crap and all these people say its crap. So, in his professional view it was crap, yet he never used it. I bought a few Mac's so I could get back to using both platforms and because I liked the idea of having both on one machine. But this I have to hate one in order to use the other is stupid. Ford vs Chevy, is either one really better than the other? No, but Ford and Chevy are real happy when they get people to believe the hype and argue about them.

    I'm not here to argue, I'm here complaining about a product that's running hot, much hotter than it should and all I get from Apple is it's normal and from Apple users I get the holy grail speech, good grief. I'll be posting temps in my next post, the PSU runs at 170f, this isn't warm, it's friggin HOT.

    Burnt, the heat needed to actually burn is pretty high, so I doubt you would. Do a search, there are plenty of articles and forum posts filled with complaints, I found them easily.

    First, you're using a PC with Apple's OSX OS on it, it's no longer a Mac, it's a PC with a new BIOS not a Mac, it also has fans, in my view they could run a tad faster and yes, if I deem this machine isn't worthy of the near $2,000 price tag because of heat I will return it. So, now can we just stick to the issue instead of the fanboy talking points?

    Agreed and also the CPU and GPU, lets not forget the very items that heat affects the most. ;)

    The computer is in my office which is my basement, it's never over 59f down here. During the summer it's the nicest temps in the house. Computers love the cool air down here, I can only imagine how hot this sucker would get upstairs. :eek:

    Ok, here are the temps.

    Fan CPU Speed 1200rpm
    Hard Drive 1198rpm
    Optical 680rpm

    CPU 91f
    Airport 124f
    Ambient 74f
    GPU 111f
    GPU Diode 108f
    GPU Heatsink 104f
    Hard Drive Bay 1 120f
    Memory Controller 106f
    Optical Drive 110f
    Power SUpply 178f

    Room temp is 59f, just got off the phone with Apple, the PSU and overall temp's (Airport HD bay and PSU) are a "concern" considering the room temp, I have to bring it upstairs and run it over night and report back the temps tomorrow morning. I'll do it and post the numbers then.

    For those of you who don't care as long as it works, ok, I understand that. For me however I expect a lot from a company that makes the claims that Apple claims and I expect a lot for the money I spend. I have nobody to complain to when I build a system, but my systems are rock solid, so I expect the same from Apple.

    I also have a Mac Pro and I am one of those people who turned up the fans (1200rpms normal use, 1500 during heavy use), simply because 12 gigs of memory make a lot of heat (memory modules in A1 and B1 hit 180f during intense use) and the only thing that will get heat out quickly, is fans.

    Here are my stats for comparison. Temps in f (please go metric, it's better) running inside a house here in autumnal Japan. The case gets hot but no trouble I think.

    HD - 119
    CPU - 104
    AP - 104
    Ambient - 74
    GPU - 122
    GPU diode - 124
    GPU heatsink - 122
    HD bay - 122
    Mem cont - 110
    Optical drive - 101
    Power supply - 139

    CPU fan - 1196
    HD - 1198
    Optical - 699

    Thank you for posting that! :)
    135 for your PSU and almost 180 for mine, very strange also of note is how much higher my airport card runs, are you wireless or wired, that could explain the difference there. EDIT: I see you're wired, so that answers that.

    What is the room temp?

    The case is designed to pull heat away, making the casing hotter then the internals. All your temps look normal. The only thing I would keep an eye on is the PSU and even thats not all that bad. In my Mac Pro my PSU is running at 170F and the next highest temp is my first memory riser which is at 156F. That said the ambient heat inside the computer is only 76F so the computer is doing a great job with removing the heat, although I am sure I could roast a chicken behind the thing.....

    I should note that the only reason the memory is so high is because the fan pushes the air through the CPU heat sinks and then to the memory risers. The memory in the Mac Pros are also supplied with heat sinks so the temp reading gets higher since so much heat is being pulled out of the CPUs and the memory.

    viking congratulations on your new imac!!

    everybody as you now can see has a different idea about temps and imacs... i will tell you what i found and what i do if its any help for you

    first yes the imac is hot this is because of the case and so yes its good to use istat pro to see what is really the heat inside

    as for separate temps your gpu and cpu should be ok as they are rated for very high temps... the most sensitive are as johto said psu and hd mostly hd

    as u no maybe hd life drops with long term high temperatures.... if you upgrade your mac every few years its no issue i think but if u want to be safe or to last longer then its good to watch your hd temp

    in my own case i try not to get HD over 50 C for a long period but its personal preference :)

    also as a vista user u should know that fan management is NOT good running bootcamp vista.... it is a very good idea to watch temps if u game a lot or do heavy work on windows on an imac

    (oh and a note....i looooove my macs and always have BUT vista is a good OS.... seriously the vista hate/xp love is just crazy IMO vista is easily easily better than xp)

    so what do u do??

    well i run istat pro of course under OSX and an app smcfancontrol also under OSX....smcfancontrol lets u manually set fan speeds (it wont go under the apple speeds tho so its safe)

    smcfancontrol is an OSX app BUT you can set fan speeds in osx and then reboot (not shutdown and startup that wont work) into bootcamp vista and the speeds will stay at your settings

    in my case i have a smcfancontrol setting for heavy long OSX work and a pretty high/noisy setting for vista gaming

    for the people who say "apple knows how to make a mac its fine you dont have to mess with it mine works fine" thats all true i dont think most people would have any problem for a year or two or maybe three BUT if u keep your machine more than 2 or 3 years or dont backup or whatever.... or if u game in windows every night :p ...then thinking about temps isnt paranoid

    wow that was long i hope it makes sense

    again i hope you enjoy your new mac!!
