IMac Quad-Core i7 Temperature Spec Question

Is there a published set of mean temperature and energy consumption tables for the quad-core iMac i7? I went through the process of transferring and adding roughly 30 GB of iTunes content and the iStat temperature and fan rpm readings spiked. What really caught my attention was when the side and top housing of the unit became hot enough that it was unacceptable to touch. I am now a bit concerned about putting my new machine in a computer armoire and want to make sure that my new machine is running within spec.
Please note that this is my fourth Mac in six years and I have never encountered this type of issue before even with a laptop sitting in my lap for an extend period of time.

Actually the GPU is located near the center, but the GPU heatsink is sitting top/right and the airstream from the fan under the optical disk drive is blowing out there.

(see the metallic box at the top right and the fan at the right bottom)
Top left is somewhat similar, there the airstream from the CPU heatsink and power supply leave the iMac's body.
However, iStat should report the CPU/GPU/etc. values. If those are okay, the hot is merely an indication for the effectiveness of the heat management, i.e. that the heat is led away from the sensitive parts to the outside via the body. From an engeneering standpoint, Apple has excellent heat management, always with noise-reductino being part of the design.
I've had the same with a 24" iMac too btw ... top left (CPU airstream) corner getting quite hot when it does number crunching. And hot to the touch 60°C are still well within the working limits of a CPU (and a GPU can still operate nicely at 90°C).
Personally I appreciate that Apple is trading heat for noise (as long as it's not a laptop burning into my upper legs).

Is iMac Quad Core Good Enough for AVCHD In Premiere Pro CS4

Hi there.
I have a quick question....
I'm thinking about buying a new 27" iMac so that I can edit my AVCHD files in Premiere Pro CS4. I'm presently using a Macbook Pro with a Dual Core and the video playback in Premiere Pro is choppy.
I also read that Premiere Pro doesn't support AVCHD without an expensive plugin.
Does anyone know if the iMac, with the specs below, will playback AVCHD in PP smoothly?
2.8GHz Quad-Core Intel Core i7
8GB 1066MHz DDR3 SDRAM - 4x2GB
1TB Serial ATA Drive
ATI Radeon HD 4850 512MB
Thanks,
David

Hello again.
I have now upgraded to an iMac, quad core i7 with 8GB of RAM. I have my AVCHD footage on a striped RAID hard drive connected via FW800 and the scratch disks on a separate 1TB hard drive that is not striped and that is connected via USB. I am using Premiere Pro CS4 to edit the footage.
When I play the video in PP, it warps on and off. It's better than when I was using my Macbook Pro dual core 4GB RAM, but it's still not playing smoothly. I have the presets set to 1080i30(60i), which is correct for this footage.
I would prefer to not have to convert the AVCHD footage, unless there is a clear advantage to doing this.I have tried converting to a P2 file, but it increases the file size from 284MB to 2.8GB.
Any suggestions?
Thanks,
David

I recently bought two iMac quad core i5 processor speed 2.5 Ghz. Every time I use Air Drop and I send a file from one iMac to the other, a black curtain drops and I am asked to restart the computer!!! What can I do?

That's a kernel panic and indicates some sort of problem either with the computer's hardware or software. Visit The XLab FAQs and read the FAQ on diagnosing kernel panics. It would help to post the panic log: Mac OS X- How to log a kernel panic.
Meanwhile, try booting the computers into Safe Mode then restarting normally. If this is simply a disk repair or cache file problem then this may fix it.
You can also try creating a new admin account on each computer then booting into the new account. This would help determine if the problem is related to a bad file in the user accounts.

12 core Mac Pro does not improve render time over iMac quad core

I'm rendering the same composition independently on two computers and they are basically rendering at the same rate, which is slightly better than 1 frame per second.
The project settings and preferences are identical in each instance (with the exception of memory and multiprocessing, which I have experimented with ad nauseum). The composition includes no motion blur, no effects, just a couple of layers of chroma keyed .mov files (using keylight 2.0) and some still images. Neither machine is running any other applications, except occasionally Google Chrome, which seems to have no effect on performance.
Both systems are running the latest version of After Effects CC (2014) and using the Classic 3D renderer.
System 1 MAC PRO:
Mac Pro 12 core 2.7 GHz Intel Xeon E5
dual AMD FirePro 500D 3072 MB GPUs
32 GB RAM
OS X 10.9.4
System 2 iMAC:
iMac quad core 2.5 GHz Intel Core i5
AMD Radeon HD 6750M 512 MB GPU
8 GB RAM
OS X 10.9.3
As you can see, system 1 is vastly more powerful, and yet no combination of memory/multiprocessing settings can get the system to render faster than system 2.
It doesn't seem to matter how much or little RAM I reserve for other applications (I have settled on 4 GB), or the number of CPUs I reserve for After Effects. The one setting that has improved performance is turning OFF render multiple frames. And even then it only brings the performance of the Mac Pro up to par with the iMac. I have cleared my cache, rebooted the computer, and read everything I can find online regarding the optimization of render settings.
Here's a comparison of the respective CPU Loads:
iMac
Mac Pro
With such a low CPU load, After Effects is obviously not utilizing the resources available to it on the Mac Pro. What a waste.
Can anyone help?

There's plenty of debate about the new Mac Pro vs a kitted out iMac. Benchmarks show that some iMac After Effects processing can actually be faster than on a Mac Pro, depending on the content and some other factors. If you're using software that has been optimised for the Mac Pro's GPU-centric architecture, like Final Cut Pro X, you will see great benefits.
mac pro vs imac
In my own facility recently we opted out of purchasing Mac Pros this year, and bought top-end iMacs instead. The benefit to cost ratio simply didn't make sense for us right now. Mac Pros are awesome machines, but a significant component of their cost is the dual GPUs, which are simply no benefit to After Effects.
Reports say that the After Effects engineers are working on a major revamp of the After Effects processing system, so I'm betting you will realise far greater benefits from your Mac pro in coming AE versions. For now, you may continue to see performance that is not spectacularly better than a souped-up iMac, depending on the type of processing involved.
I've seen a few benchmarks that suggest the 8 core systems give better bang-for-buck than the 12 cores. Try reducing your processors to 8 in After Effects and see if it makes a difference. With 8 cores, allocate 3GB of RAM per core to leave some RAM for the OS.

Will illustrator cs2 run on imac quad core?

will illustrator cs2 and photoshop cs run on the new imac quad core? if not, which versions will run?

Only the very latest versions will/could have updates for 10.7 Lion as the OS was just released and doesn't run "Rosetta/PPC" based programs which those most likely are.
Guess you milked Adobe for as long as you could, perhaps you can buy a used machine?

LE 9.0 performance on Mac Mini (dual core) Vs. iMac (quad core)

I am in the process of evaluating options to replace my 2007 MBP with a faster DAW. I am on a budget so while I am looking for performance improvements over what I have, I don't need overkill either. I am considering the 2011 Mac Mini (2.5 GHz, dual core) and the 2011 iMac (2.5 GHz quad - core). Whichever configuration I choose, I will bump up RAM to 8 GB.
I use LE 9.0 and a Presonus Firestudio Project and would like to know whether what kind of performance improvements I will see between the two options I am considering. I use a lot of plugins, and an external Firewire 800 drive for recording. Obviously with the Mini, I will have to buy an optical drive as well. I already have two monitors, keyboard and mouse.
The only thing that worries me about the Mac Mini is the slower 5400 rpm hard drive. While I plan on using an external drive for recording, I am concerned because of the number of plugins and sample files that need to load during recording / playback.

Lion Server on 27" iMac quad core...

Greetings...I have a quad core 27" iMac w/8gb of Ram & 1tb hard drive that I want to install Lion server on. From other posts, I gather this is not really a problem...but I am wondering:
Can user could be logged into the Lion server and working in their home directory while other mac users are logged into the server on their macs? At most there would only be 3 other users logged in at the same time on the iMac server...so it is not a big network. Also...I only plan to use the server for file/sharing home directories.
If the answer to #1 above is "Yes"...when a user logs into their account on the iMac server...would they see the "Server" apps on their dock?
Any...my goal is to have home directories on the server and users to log into the server and see their own home directoy/desk/etc from any mac on the network AND if they sign in on the imac server.
Any direction is appreciated.

You are going to deploy network accounts (Open Directory aka OD) with network home directories (OD+AFP).
Server.app application comes with MacOSX Server, so there will be no MacOSX Clients with this application in it (unless you copy it, or share through AFP or SMB, and i don't know if that will work...).
You can (and probably should) install the "Server Admin Tools" in your MacOSX Clients.
You can install MacOSX Server in a client machine, and have the Server.app in a client machine (with a server operative system).
I remember there was also "Network Applications" and "Network Library" implementations in OSX, but i've not seen any reference since years ago...
This last two implementation allowed you this: centralized applications, and centralized preferences (now that last is done in other way).

Imac 20'' Core Duo memory specs

Hey,
im thinking to expand my imac's total 1gb ram
and im really confused from what i've read about the memory amount a ram module
should have.(some say it can be expanded to 4gb(3gb used))
I know for a fact that it can be expanded to a sum of 2gb (2x1gb).
Is there a way to find out?
I bought my imac on 06/2006 but i cant be sure which imac is(early or mid 2006) as im not living in the states or in any other technologically "advanced" country.Forgot to mention that the model is imac 20'' intel core duo
cheers.

HT1338 just bought a 27" iMac quad core i5 and when I try to install Logic 8 it tells me that its not supported by power mac

Just bought a 2011 imac 27" to upgrade from my MacBookPro 17" to run Logic 8, but when I try to install Logic 8 on the new Mac I disappointingly get a message to say that the application is not supported on power mac, that cannot be right, or can it. If so what do I need to do to get it to install?

Logic 8 has a "bug" in its installer program that makes a newer Mac (Lion, and thereafter) think that it is PowerPC, but it is not PowerPC.
Try using Pacifist to install Logic 8 in Mavericks:
http://www.charlessoft.com/
If you cannot get Pacifist to work, you can partition your hard drive and install Snow Leopard into that new partition, install Logic 8 and then upgrade to Mavericks.
As Barney correctly points out, the 2011 iMacs require a minimum of 10.6.6 to boot, so that you need to install Snow Leopard with one of these three options:
1) As Barney points out, the original grey Restore DVD that came with that iMac (or a replacement provided by Apple if you call with your model and serial number);
2) The slipstreamed version of the Mac OS X Snow Leopard Install DVD at 10.6.7; or
3) Install Snow Leopard on a new partition on another older Mac, update it to 10.6.8 and then clone the partition and move the cloned partition over to your 2011 iMac.

HT4430 can i restore my imac quad core system from a restore on a flash drive? and if not how do i go about getting another copy of the one for my imac?

Hello I am having a serious issue here and with my limited mac skills i feel like im in a bad spot of potentially loosing everything on my hard drive. i cant replace many of my photos of my daughter and i have videos i have saved from performances i have no way of getting them anywhere else.. help
i need to find a way to get my system up and running it keeps asking me for the OSX but says there is a problem with the install and wont go any further.
I maved earlier this year and as my apple care ran out so did the location of everything i tried to organize so well. my RESTORE disk IS LOST!!! Grrrrrr
Help what do I do? Someone out there in Mac Land please advise me of your supreme know how!
Thanks for your time and I can use all the help I can Get!
Sincerely,
Summerlynn Rivera

You need to contact Apple Customer Service about purchasing replacement discs for the computer. You have posted in the PPC forum, so I assume you do not have an Intel Mac, but since you haven't stated what you have we simply don't know enough to assist you.

CS1 on an Intel iMac Quad core i7

Is it possible to get this thing running? Everything works except Photoshop, which is what I need most; error message says:
Could not complete your request because of missing or invalid personalization information.
Adobe would not, of course, help.
This is an educational version I bought legitimately from the university bookstore; I am the registered user/owner. I DID have the software installed on an older machine whose power supply died, and can no longer be fixed (11 year old Mac), so maybe it is an activation error (that's what it sounds like). I am about to buy CS5, but just have to wait a bit for my bank account to recover from this computer purchase (and the university bookstore doesn't HAVE any copies of CS5 yet, anyway, even if I had the money).
Any help would be greatly appreciated.
Cheers,
Cameron

CS is unsupported on Intel Macs and under Snow Leopard or Leopard. The chances of getting all of this working well are not great and indeed moving to CS5 is your best bet.

I download the 3.2 update from 3.1, but it does not install. I am using system 7 with an iMac quad core, which works fine, but it won't update.I don't know what to do

I can't upgrade from 3.1 to 3.2 Bootcamp, despite multiple attempts to download. it seems to download but the upgrade does not install and I don't know where to look to make it install. Any suggestions?

You are in Windows; you already have inserted your OS X DVD and run SETUP and installled Boot Camp 3.0.x (shows in Windows control panel: Programs and Features.
Start => Apple Software Update (also in Windows) will download and install updates as well.

"iMac 27" with quad core with an ATI Radeon HD 4850 512MB video processor"

I'm about to order a new iMac 27" quad core with an ATI Radeon HD 4850 512MB video processor.
I'm a long time PC gamer but decided i want to make the full switch to Mac and I have a few questions about the graphics capabilities of this computer.
I game in a clan that plays Battlefield 2 Project Reality.
Will this card handle this game at the high settings and native resolution of the monitor? I also play COD4 and have the same question for that game.
Thanks for your input. I'm sure this will be helpful for all of us and I will share it with my clan of over 100 people strong.

Yeah it plays crysis fine, here is a video of me playing it:
