Nov 19, 2010 2:24 PM in response to Supermike530by Simon Baker,I have had no freezes for the last week with the fans ramped up with SMCFanControl. I have a screen shot, but my ISP has changed its freespace settings and I have given up trying to upload it. In any case, there are 3 settings for the minimum fan speed under preferences. I have them set on ODD 1948 rpm (optical disk drive, appears nearest the GPU heatsink, I think); HDD 1200rpm (Hard disk drive); CPU 1554 rpm. Its not too noisy, but you can hear the whirrs.
Running on 10.6.5 with all updates installed. I even reinstalled the last Graphics update, just to make sure. When I'm feeling masochistic I may turn down the fans and see when the freezes kick in, and report. Very many thanks for the Apple problem link, by the way, I just could not find it! -
Nov 22, 2010 9:52 AM in response to DazzaGby Sorkin,Went back and installed 10.6, did the 10.6.2 Combo update. Installed Pro Tools 9 again. Been surfing in Safari a bit. No freeze yet. Fingers crossed....

Nov 22, 2010 2:28 PM in response to DazzaGby pika2000,I've been having similar stability issue after recently upgraded to Snow Leopard. My iMac is the 2008 model, never had a stability problem while on Leopard. I upgraded to SL recently to 10.6.5, and it will lock up randomly. The occurrence is random, sometimes even while I'm doing nothing, but the iMac will lock up (frozen entirely, mouse not movable, sometimes with a spinning beach ball seconds before, sometimes the iMac's screen just turns black) and my secondary display will show a green screen with some vertical lines (this happens all the time when the iMac locks up). Thing is, since it's random, I don't know how to get proper technical support. I did all the standard troubleshooting methods. I even ran the Techtool diagnostic, and everything is shown to be fine. -
Nov 22, 2010 3:41 PM in response to DazzaGby KrzysiuTurek,First of all sorry for my bad English, I'm writing from Poland
I'm currently testing Simon's solution with SMCFanControl... and in my case it works fine. My fans settings are:
ODD: 1031rpm
HDD: 1200rpm
CPU: 1273rpm
and my mac is running in 64-bit mode.
No freeze from 3 days!! -
Nov 22, 2010 11:11 PM in response to KrzysiuTurekby SeSam,I have also tried SMCFanControl. For a while it seemed ok but after a few days I encountered another freeze. Fans were at 1200-1500 RPM each. -

Try this setting.

I haven't experienced a freeze for 6 days, which was impossible before.
I updated 10.6.5 right after Apple released and as expected the freeze happened again. I CAN not understand why my system lock up while just surfing the web on Safari.
So I installed SMCfancontrol again. -
Nov 25, 2010 12:20 PM in response to Simon Bakerby Zachnap,it won't work. I've had this problem since 2007-08 and my fan rpms are at 3600. You are lucky your system lasted this long. -
Nov 25, 2010 3:08 PM in response to Zachnapby kingmatteo,I have the same problem with my iMac 21,5" 10,1.
Just from when i bought it, March 2010, i had experienced many times freezing.
All the time when i surfed the web with Safari. In the first time i believe that Flash plug-in was the problem, but now i'm not sure about this.
This mac is placed in my room and i usually work for just 2 hours 3/4 days at week. But when i work with iMovie for 3/4 hours no kynd of problem, when i'm using Safari ( and just one time with Chrome) freeze happens.
I made all the test with techtool deluxe (except surface scan that i try to launch in this week-end) and no kynd of problem.
After the surface test i will call Apple in Italy ( i bought an Apple's care program) and try to understand if something.
Besides this, i have a question for all of you that have this problem: are you connected to the internet via Wifi airport or Ethernet Cable ?
Bye

Nov 25, 2010 3:28 PM in response to DazzaGby KrzysiuTurek,Couple of minutes ago I try to reply to this post, and boom... - another black screen.
But this time my iMac is connected to the external HDD
Tommorow I will go back to 10.6.2.

Nov 26, 2010 6:11 AM in response to kingmatteoby Tazthed,It has nothing to do with WiFi or Ethernet Cable.
It is probably the graphics card. Apple just doesn't want to solve this issue even though a lot of people are complaining! -
Nov 30, 2010 6:56 AM in response to Tazthedby Mauricio Costa,The problem is the location of the graphics card inside some iMacs. It happens that the CPU seams to be too close to the Graphics Card in the 2007 24" iMac (mine). The heat causes freezing and funny elements showing up. The solution I found (like many) was to bump the fans to the max by software (I use "Fan Control").
But after 10.6.(I don't know exactly) my system started to crash again, specially when using Safari (?)
My guess is that Apple is pushing the GPU use forward with the new versions of their OS and softwares. This is probably heating things up... And here in Brazil the whether doesn't help much
Is there any chance for us to get organized and transform this in a "GPUGATE" or "FREEZEGATE" for the lack of a better name? Any suggestions?? -
Nov 30, 2010 7:05 AM in response to Mauricio Costaby Mauricio Costa,Repeating what someone already said, please do a formal report to Apple:

I'm doing mine right now... -
Nov 30, 2010 7:37 AM in response to Mauricio Costaby Mauricio Costa,Below I copied my report I sent to Apple:
As you probably know already (we hope) the first Intel iMacs suffer from bad design/bad components resulting in freezing, crashing and "special effects" overall.
Like thousands, I am a 24" 6,1 Model iMac owner (running 10.6.5), and like them, I had the same problems... (I thought this was something wrong I was doing!!) but later I identified that the problem as being a bad design issue - the GPU was too close to the CPU, what made the GPU too hot, resulting the issues described.
After some research I found MANY people around the world share the same problem. And not only with the same model iMac!! I found also that controlling the fans by software I could reduce or in my case, solve the problem. It happened though that after one of the last System Updates, my iMac is freezing again... I guess the Apple engineers are not doing there homework (trying to be polite now).... wouldn't the extensive use of the GPU in OS tasks make the problem even worse for us??
I'm a 11 year Apple devotee and I am deeply FRUSTRATED.
Not only.... I really cannot trust if a new iMac would solve my problem...! How could I trust Apple again? You people don't even recall this machines!?!!
If all this is so new for any of you in Apple (I hope not), please read this tread ( http://discussions.apple.com/thread.jspa?messageID=12680036#12680036 ) and many others that got archived.... they are just a fraction of the users... many are now thinking they installed a bad RAM, got some new virus or just weren't lucky.
Please Apple, be honest with the people that gave you so much... Now it is time to pay back what you owe. -
