CPU positioning

the Main CPU is position right under the top right hand corner of the machine; hence the high temps.
 
Here is mine... a bit high but I took the readings while running iTunes with full screen visualizer.

Mac HD: 55 degrees Celsius
CPU A: 44
CPU A: 34
GPU: 72
GPU Diode: 72
GPU Heatsink: 77
Ambient: 26
power supply: 81
Northbridge: 77

Fan speeds:
CPU: 1912
HD: 2835
Optical Drive : 962

So that is hot huh? I live In Las Vegas and it was hot today. about 80 degrees in the house.
 
Ok to catch you up to date. I emailed Tim Cook, the acting CEO of Apple while Steve Jobs is taking some time off. I got a phone call from his team. They had a High Level Tech Support Specialist contact me today and they gave me a program to capture my logs to trace why my freezes have been happening. They are putting a High Priority on it and I should know something within 24-48 hours. I will relay the findings here.

I did ask her a few questions regarding fan control, I see on this site that some of you are installing smc and other software and making your fans go faster to cool down the temperatures. She told me that it is not recommended that you do this, and that is because it will make your fan not last as long as it should for one thing. That alone is good enough for me. I did install istat to monitor some readings. She said that is ok, but they are not 100% accurate. But they will give you some idea of what is going on.

Also did you know that on your 2nd DVD install disk where applications is on there is a Hardware Test program. The instructions on how to use it is on the disk. You can try that if you like. Mine passed ok.

According to this Tech Support Specialist, the Apple Engineers do not have enough data yet and needs to collect as much as they can to figure out the program. So from that I think this will not be a quick fix. We are probably looking at least a month at the earliest to see a fix on this and maybe longer.

This of course is only my opinion and I could be way off. If you get a chance, call your Apple Tech support and tell them that you want to discuss with a High Level Tech Support Agent and give them your logs for the engineers to look over. The more logs they have to review the faster this fix will come. The program they use to capture the logs is called CaptureData81.

It will capture only the crash logs and make a DMG file in which you will upload to send by email back to the Support Agent. If you want a faster fix, then do this today. Contact Apple Support and tell them that you want the CaptureData81 program and that you want to give them your logs for the Apple Engineers to review. The more logs they have the faster we will get rid of these lockups. Hope this helps.

Sorry to repeat myself on these threads but I wanted to make sure more people see this and take action so we can get the fix faster.
 
imac 27 inch reboot issue to run smc fan controls on windows

hi guys....been getting some problems with my imac 27 inch when rebooting to run windows 7 with the current fan speeds set on smc fancontrol...the computer does boot the windows....i end up having to hold the power button n haveing to run windows with out my set fan speeds in smc....can anyone help me?....is there a progrom for windows 7 that can enable me to control the fan speeds so it does get hot?.....thanks:)
 
iMac 24" running temp ?

I have iMac 24" and build early '08. Upgraded to 10.6 Snow Leopard. My iMac running temp as screen shot below, is it normal temp (in F degree). Please guide me. Thanks.:apple:

I've had some serious performance issues lately with my 24" iMac. SMART Utility 2.1.2 shows that my drive is failing with only 7020 hours on it. It also reads 58 degrees celsius- something iStat Menus corroborated.

Even at this high temperature (for hard drives), the fans were barely moving. smbFanControl brought the fans up and the temperatures to a more reasonable level (51 degrees).

I understand users' sentiment about trusting Apple engineers, as I am an engineer myself. Apple always makes good on replacing hardware that was killed in the process of regular use.

However, I would rather lose a fan than lose a hard drive. A lost fan will be noticed immediately and can be replaced. A lost hard drive's data is irreplaceable, so I will be erring on the side of caution. I suggest that all of you do the same.
 
so what does apple say about temps?

i've searched and searched for a statement from Apple about acceptable internal temperature ranges. i have found squat.

i live in the desert and it's hot hot hot. sometimes i get by with just a fan even if it's 95F inside. i had been watching my temps with iStat. by evening yesterday, i finally noticed the sounds of 1 or more fans. ok, they're working hard, so better get clear about acceptable temps.

today i found the posts on MacRumors where people posted their temperatures. some posts indicated temps not far from mine and reported having no problems.

i'd still like to know what temp ranges Apple thinks are normally ok to operate without causing damage. i'm puzzled the info isn't easy to find? they must have their reasons, but.....

so how can i tell if the temps are causing a problem or are likely to?

thanks.

here's my stats today:

well, i was going to add a pic of them but don't now how. if someone could tell me that too, that would be great.

here's a couple:
ambient temp: 88F --- 30C
HD bay: 131F --- 55C
cpu: 142F --- 61C
optical drive: 120F --- 49C

fans (rpm)
hd: 2476
cpu: 1203
optical drive: 799
 
On my iMac 24 w/ 4GB, 500GM 7200 hard drive

Some history:
Bought computer late 2008.
- mid 2009 - Hard drive failed and replaced under Applecare
- mid 2010 - hard drive failed again and replaced under Applecare
- few weeks later - computer super hot, fans full blast, burning smell. Apple replaces logic board and video card but wouldn't replace the machine.

Since getting the computer back I am seeing the following:

Power Supply: ~180 F
CPU 1 and 2: ~140 - 170 F
Airport Module: ~160 F
The rest of the items are in the 120 to 140F range.
Ambient temp is around 74F. Don't really hear the fans much. Not sure if they are even working.

Are you on the floor yet? :eek:

Apple doesn't seem too concerned. Most of the people have been very nice in getting things fixed (although they do tend to slip on their delivery dates). I have another ~8 months left on warranty so shall see what happens but does anyone agree with me that this is way too hot? Based on the comments on this thread, guessing the 2 previous HD failures are due to high temps all along. I didn't monitor or worry about temps until this past episode.

Will post if anything develops.. guessing another failure and I will throw a fit like a 2 years old girl to get the computer replaced. Would like to hear if anyone has had any similar experiences. Thanks for the good color.
 
temperature of Apple 20" IMac - Intel chip

I just installed Thermographx, which I used to use on my old bondi-blue Imac I believe - because my Imac feels hot at the top a lot. I also do the SETI - at home project at Boinc on my computer.

The readings show temp about 190 Fahrenheit, which my conversion app shows is about 87 Celsius. Delta shows 4. Minimum 174, max 192

Not sure what "delta" is -

I got this program off CNET.com, under Mac downloads - there are other temperature sensing utilities listed their also. I just chose Thermographx because I had used it before.

Thermographx did mention on their site that they have problems where some manufacturers deliberately deactivate their sensors "reporting" ability, and they may have problems with some sensors. Maybe a different program would give me different temp readings. :rolleyes:
