I recently got my 3.2ghz mid 2010 21.5' imac. I noticed that its been getting really really hot on the top on the top left and right corners of the computer. Usually i am watching tv series (.avi) files on it using quicktime and vlc and i checked the temps reaching these as follows
HD 54
CPU A 50
GPU diode 71
GPU heat sink 68
memory 58
optical 51
and the fans are at

I have a new macbook, see stats below.
Up till last week everything was fine, I could run 'Second Life', photoshop, email, a browser, download stuff, play Itunes AND watch a movie all at once without any trouble.
But recently the computer has gone a bit weird.
It started getting very hot, much slower and turning itself off.

I just bought a brand new imac running 10.5.7 3.06 Intel Core 2 Duo 4 GB 1067 MHz DDR3 i downloaded Handbreak to rip some of my dvd's and put them on my external hard drive as soon as i open handbreak and start ripping a dvd, the fans in my computer start whirring away, pretty loudly i downloaded the istatnano widget to check my fan rpm's and temps
While Running Handbreak:
Fans:
CPU Drive - 3605 rpm
Hard Drive - 2408 rpm
Optical Drive - 2195 rpm
Temps:
HD - 57
CPU A -46
CPU A - 80
GPU - 53

iMac is been in on the repair bench more times than I can count. Luckily, most of it was under warranty. But I was just wondering, if anyone here's got the same system (or knows someone that does) and has 'modded' it to run cooler?

I got an iMac i5 recently, and I've downloaded iStat. It seems as though the HD hovers around 55C, and I think 60C is the maximum. Are there any precautions I should take, or is there nothing to worry about?

I don't know if it is a fan or a drive that starts up and runs really fast and loud, then the computer shuts off. I always thought it was the fan, but now am not sure. I have moved it to a place where it is exposed to more air, but that has not seemed to help. Does anyone have an idea or solution to this problem? The nearest Mac dealer is about 80 miles away, so if I can fix this on my own, I would like to try.

My Imac freezes up a lot, usually after 10 to 15 minutes of being on. I suspect it has something to do with overheating. I have to get my data off of the drive before I take it into the Apple store for fear that they will will just replace the drive and all will be lost. I have a fan blowing on it now in the back and am copying data onto an external drive little by little until it freezes up.
I bought it last fall and have a 3 year warranty on it and this will be my second time bringing it in for repair. The first time it was a problem right out of the box when I brought it home and it was replaced. It's a 3.06 processor, 24 inch screen. I am not impressed by the hardware reliability and the all in one system. I am regretting buying the imac after being a PC user for so long and I am using my Windows PC to write this. I suspect the cooling system could be better on my IMAC given the compressed footprint.

I've been having trouble with my new iMac that i purchased recently (26th of August actually). Whenever I'm doing something CPU intensive, the machine just shuts off, but usually it's not right in the middle of whatever I'm doing, it's after I close the application. For example: I was playing SimCity4 the other day, pretty old game to cause this problem I would think. As soon as I exit the game, the system shuts off. No warning, nothing, just shuts off. This will happen when i close VMs (it actually happened yesterday while I was running the VM), etc. So I've reset the SMC/PMU, PRAM/NVRAM, and I've even reseated the RAM. Still the same problem. I've taken it in to a repair center in town, hoping I'll get it back by the end of the week. Does anyone have any idea why this would be happening?

Yesterday a friend gave me a really nice 17" iMac G4 he was planning to throw out because it was having problems. I would really like to get this working and would potentially be willing to buy parts to repair it. I have a significant amount of Apple hardware experience, but would like to get the opinions of people who may be more familiar with iMacs than myself on these forums. The problem is that the computer has random kernel panics. Sometimes it occurs as soon as the computer is turned on, sometimes after it has been on for a few minutes, sometimes after a few hours. So far, I have replaced the RAM with known good sticks, have replaced the hard drive with a tested good one from my collection (and these were both upgrades to boot!) and I have re-applied thermal paste (Arctic Silver) to all key components (CPU, ends of heatpipe, GPU) but to no avail, I still have the same problem.

I was using my Imac G5 (pre iSight) and it suddenly shut down. It smelled of burnt plastic so I immediately disconnected the power and all accessories, laid the computer down, and took off the cover. Everything seemed normal, except the smell of burnt plastic coming from the fan and faintly from the power supply. I took the metal piece covering the fan and hard drive, and attempted to clean the fan. After about an hour I put the cover back on, plugged my computer back in, and started it up. It again shut down after about half an hour of use. What's wrong? Do I need a new power supply? I checked the Apple Recall and my serial fits, but the symptoms do not follow the ones in the recall.

I have brought a new iMac 27'' the i5 model. I have noticed that the fans never change speed no matter how hot my processor gets ? Is this normal ? I have ran prime 95 and istat pro to check the temps and fan speeds. Nothing changes apart from the temperature.

iMac, Mac OS X (10.7.3)

Ive had my Imac for about 9 months and havnt had any issues with it until the past 2 months. The first issue was that i would leave it running for the day and i would restart and get the flashing folder issue. I would then go through all the appropriate steps- unplugging from the power source for 45 seconds +, try booting it with the OSX cd in, ect. At first these steps worked. The next issue i had was a power outage. I followed the same procedure when i went to start my imac up again (mind you it was within 10-15 minutes of it being turned off) and these steps did nothing and the flashing question marked folder appeared every time. I called Apple support and after 2 hours they insisted that it was a faulty hard drive. I let the imac sit for the rest of the day and before i went to bed i decided to give it one more shot. It booted up just fine.
Ive come to the conclusion that im only getting the boot error when it has been running for long periods of time and that the casing feels hot when i try restart. I was wondering if you guys could let me know if my theory of over heating causing the boot error is correct, and if so is there anything i can do myself to help correct the problem? I really want to avoid going to a mac store because its so far away from my location.

I have an iMac G5 that is starting up, then working okay for 1-2 minutes. After that, the processor usage goes way up, and the fans start spinning loudly. It's a first generation 1.8 GHz with a 17" display. Mac OS X Leopard. Recently, it spun up and then shut down and wouldn't start again. The room it's in is < 75 degrees F. No malodor, or other symptoms save for hot to the touch. Has been left shut off and unplugged for a few hours, and still has this problem.

I'm wondering if anyone could post what your regular temps for your 2010 i7 iMac (or i5) are as well as what your temps are under load in Mac OS X; interested in all of the temperatures listed in iStat Nano but primarily CPU, GPU, HD and OD (optical drive).

I have an opportunity to get a Late 2009 27" i7 (2.8 Ghz) for $1699. I've been looking at the $1999 i5 (also 2.8 Ghz). I know it has a 1Gb Video Card, compared to the 512 MB one on the 2009 i7.
My basic question is, is the i7 worth the lesser video card and cheaper price, compared to the i5 with a stronger video card?
I do a lot of work in Photoshop and iMovie, as well as Illustrator and inDesign. I also will be playing TF2 heavily, and heard that the i7 was great for video and gaming. I'm in the market for an iMac since my Late 2006 Macbook Pro is on the verge of death.

I have a question about the iMac core i7 between both year (2009 and 2010) for 2009 is 2.80GHz Core i7 with 1066 Ram. for 2010 is 2.93GHz Core i7 with 1333 Ram. Is the 2010 faster than 2009 a lot?

I very recently purchased a refurb late 2009 27 inch i7 iMac. It is more computer than I currently need. I do have one concern that SSD is supposedly much faster than a conventional hard drive and although a solid state drive is now pretty pricey, they will come down in price and I suspect become more mainstream over the next couple of years.
Does it make any sense to consider swapping my computer for a late 2010 i7 refurb (+ $200) so that I have an upgrade path to SSD in the future?

How does StarCraft 2 perform on the current lineup of the iMac? I'm most interested in the 21.5" model, as I cannot afford the 27" version. Specifically, I'd like to know what resolution and settings the 4670 and 5670 models can handle...

I searched the forums but can't seem to find a definitive answer in regards to having a loose hinge on the i7.
I picked mine up yesterday and it seems a little too lose for my liking. It stays in place when it is not touched, but if you push with one finger on the bottom it will switch quite easily.
Is this how they make the hinges now or is mine too loose and should be exhanged? I don't seem to have any problems with dead pixels/yellow screen/noise and would hate to exchange it.

I ha e 2x2gb of 1066 ddr3 ram sitting here. I am going to buy an iMac. I can't decide between the refurb 27 core2duo, the refurb 27 core i5 or the new 21.5" i3. Of course I am torn between cost and performance. I would prefer the bigger display but it's not necessary. If I could use my existing ram in the new 21.5 that may put it as the winner but I am unsure if I can mix 1066 and 1333 ram or not. If not then I will probably get the refurb 27 and then it's just to decide between i5 or core2duo

I have a 2010 iMac that won't start when I press the power button. No chime, no fan running, nothing. I tried unplugging it and plugging it into a different power source which made no difference. I made sure the power cord connections are good. We recently had an 8 hour power outage at my house and this is the first time I tried to power the iMac up since the power outage (it was working fine prior to the power outage). Of note, my husband's iMac started up fine after the power outage.

I have an iPad 32GB WiFi and a MacBook Pro as well so I was trying very hard to justify myself in getting an 11" MBA but ending up talking myself out of it. The 13" MBP is perfect for my uses. It's already lightweight and portable as it is. After playing with the 11" in the Apple store, I was impressed on how light it was. This no doubt blows away any netbook or any notebook in it's weight class in terms of size and performance. However, the MBP's battery life, hard drive space, and processing power OUTWEIGHS the reasons of dumping my 13" MBP for the Air. Also, I have it hooked up to a 21.5 Inch HP monitor at home and it's good enough to use as a main computer at home, and light enough to take on the road.
If I needed to lookup something quickly in bed or around the house, that's where the iPad comes in. If I needed to send a quick e-mail, my HTC Evo is already great at doing that. If I didn't have a 13" MBP or even the iPad, I would have most likely went ahead and purchased the MBA. Just now at this point, spending another $1000+ or getting rid of my MBP doesn't make much sense... yet.

Has anyone tried using their mid-2010 imac with hdmi and can confirm if audio (out) works? All the adapters seem to claim audio support with the refresh macbooks but do not mention iMAC. On the Apple store they sell a moshi adapter that lists iMAC support but specifies early-2010 models. Is apple deliberately crippling the new iMACs to *not* allow audio over displayport>HDMI or what is the real story? Some older support threads seem to talk about it working on their 2009 imacs until they upgraded to os 10.6.4. I have tried a few generic cables/adapters but they don't seem to talk audio to my receiver. Anyone had better success?

Currently have 4GB of ram in the iMac.
What would 8GB do with regards to performance within OSX and Win7 64Bit
The iMac is a i3 3.2GHZ
I play SC2 and TF2 in OSX and Win7.
I can get this [URL]
so i'll keep the 2 x 2GB already in the machine and just add another 2 x 2GB sticks for �50
Or am I wasting my money ?

I've got a 27" imac i5, with 4 RAM slots. I do actually have 2x2Gb installed, but that's not enough to run windows 7 smoothly with Parallels.
I would like to upgrade the RAM. Can I buy 1x4Gb now, and add another 1x4Gb later? (short on money at the moment...)
The two original modules are installed in BANK 0/DIMM0 and BANK 1/DIMM0. Should I install the new module in any free slot available?
Another question: is this memory fine?
PATRIOT SODIMM DDR3 4GB(1X4GB)1333Mhz MacCompliant
I read some topics about ram upgrade, but it's not clear wether you can add one single module...melagodo

Like the title says, OWC aka Macsales.com is offering to drill an eSATA in your 2010 27" iMac for $169.
Awesome but Apple should have done this for $1
