Brand New 20 inch iMac overheating.

I did try the suggestions before I finally decided to take it back. I love it when it works, but I feel quite disappointed how everyone praises apple and some people in this thread were like no nothing ever goes wrong with a mac and I somehow end up with problems with both macs that I've had.

Well, as they say, **** happens. People's Macs break all the time, although, statistically speaking less than any other computer makers machines (see Consumer Reports for the numbers). The problem is simply that you don't seem willing to let Apple fix this for you. Bring it in, get a new machine. You HAVE a GOOD solution, but it's apparantly not good enough for you. So, take your iMac back to the store and get your money back and buy a different computer and a Zune or something.
 
I just find it funny that you guys are giving him such a hard time with comments like "we told him how to fix it he wont do it and "go buy a zune" and just the mac4lyfe attitude. Now I own the new 20" alu imac and have had no problems with it so far, but this poor guy has had to return his mac twice, so he comes online for some advice thinking maybe it was something he missed.

Theres is constructive feedback which helps, but are the comments above really necessary? why should he go buy a zune? If he isn't happy with his experience so far, let him do what he wants, I just dont see the need to give him such a hard time just because he wants to buy a pc.
 
hmmm there seems to be other people with the same problem if you look at the other threads in this forum... maybe its a problem with the 20inch alu imacs?

I'm on my second iMac in a week (my first one decided that it didn't want to turn on anymore) and I'm having a serious problem with overheating. Whenever I burn a cd or read from a cd (for example, installing windows xp) the machine shuts down with no warning or anything. I assume it's overheating because, well I can't see any other reason for it do this. The disks are hot as well when I eject them.

I'm really considering getting rid of this iMac and switching back to Windows, after just singing the iMacs praises in another thread. These are also my first ever iMac's and they haven't made a very good impression. When it works it's incredable, however I'm on my second one because of stupid problems with them.

Anyone had any experience with this before and know how to fix it?

Thanks in advance.

I took it back and got a refund. The mac genius guy said it was something to do with the network card shutting the computer down for some reason. So there was a problem with my mac, maybe the network card is behind the cd drive or something.

Have fun with your macs guys.
 
hot is not

I purchased a 2.4ghz 20in iMac last october....about a week ago when the screen was on energy saver, the tunes were cranked and I was burning some toast, I noticed what looked like a giant palm smudge on the upper left corner...after a wiping down and a closer look, I determined it was not a smudge but some sort of "stain"...I couldn't figure out what would cause this until I touched the upper left corner! You could melt cheese slices on that thing! The aluminum was almost too hot to stand and the plastic was no picnic... I'm no genius, but electronics are not supposed to get hot, luke warm sure, but hot enough to stain your screen from the inside?
Guy from support says I got a lemon, but couldn't figure out what would heat up in that corner, as there's "not much in the top left corner?"
Anyone else having screen issues? I've read a few concerned with overheating and a few more saying, it's supposed to get hot?? Not to my knowledge...

Bad luck mate. Of course, everything has a failure rate. The XBox 360 has an appalling 16% failure figure for example.

We've bought 6 Macs in our agency over the last few years and every one has been flawless. I'm surprised you've had such a hard time and there's no excusing Apple for selling you those shoddy products.

But, I still think you are shooting yourself in the foot by walking away. There will always be a tiny number of lemons out there and somebody somewhere will end up getting 2 or 3 on the trot just by the law of averages.

I bought a refurbished iMac 20" aluminum 320 GB, 1 GB memory... basically the last version before the current ones.

The first one I received got HOT, HOT, HOT on the upper left top, and very hot on the upper left side and back.

I got a return and the one I am typing on right now gets hot, but not quite as bad as the first.

I have iStat Pro, and the internal temperatures are within the range of a friend's iMac. He is basically a geek and has told me that my temps are within acceptable range according to everything he's read on the internet (and he is up-to-date on EVERYTHING when it comes to Macs and PCs).

So, if my internal temps are within range (although higher than the iStat Pro image posted earlier), am I okay?

Do other people's aluminum iMacs get hot on the top left and back when using them basically for internet browsing, email?

Just a sec... I'll get my iStat Pro stats and post them here. Be right back...

CPU A - 44 C
GPU - 58 C
GPU Diode - 62 C
GPU Heatsink - 59 C
Ambient - 26 C
Mem Controller - 47 C
Airport Card - 47 C
HD Bay 1 - 50 C

So, do I have anything to worry about? Do other people get the same heat on their aluminum iMacs?

I need to know quickly so I can return this second one if needed.

If anyone knows if the now shipping iMacs have changed other than the processor speeds, and the cooling design has changed, I'd like to know that also.

Thanks in advance!!!

I think its a heat issue, to do with the latest firmware or leopard updates which control the fans and temperatures on various models and machines.

SMC Fan control solved the shut down freeze thing for me. but on a white imac.

I think the temperature reaching far too high is causing the shut downs.

I have taken 30c off my internal temperature by using smc 2.1 with only a slight increase of fan speed.

Before that I thought it was a component failure, and the end of my online Life
