Unfortunately they had problems sourcing a replacement graphics card and after many weeks of waiting they offered to either continue waiting for the replacement (unknown ETA), or replace my 3yr old 24' iMac with a brand new 27' 3.06GHz C2D machine. (this matches what I have read on various internet forums - that this problem is due to the graphics card in this model iMac) we reproduced the problem in-store by running a lot of graphic-intensive apps, a bunch of flash-heavy websites, and even partially blocking some of the airflow vents on the machine.Īfter replacing the logic board and fan, they still said they weren't satisfied the problem was solved and ordered a replacement graphics card. they confirmed it was a hardware problem and replaced the logic board and CPU fan which seemed to be running a bit slow. Since I had a month left in my 3 yr AppleCare warranty I brought it into the AppleStore. usually just single horizontal line would be corrupted. Problem a) could occur no matter what application was running, even just within the Finder. The problems would only occur when the machine was running hot. it had intermittent heat-caused graphics problems, specifically:Ī) occasionally, random horizontal lines on the display or within a window would become corrupted, orī) when running 3D intensive apps, there would be massive graphics corruption over the whole screen, eventually leading to a severe random crash and lockup of the machine. Until recently I had this model iMac 24' 2.33GHz with nVidia GeForce 7600GT graphics card. When I replaced the GPU, I also replaced the hard drive, and unfortunately I broke the original thermal sensor - hence my use of HDD fan control (using the hd's internal sensor instead).įyi I can share my experience with this machine and this same problem. This specific model is susceptible to heat more than other models. Last - Only use your iMac in a cool environment. Second - I've been using both smcFanControll and HDD fan control to increase fan speeds beyond Apple's standard, again, to reduce the temperature on sensitive electronics. On my machine everything gets clogged with dust. Bottom and back ventilation holes, all internal fans, Heat-sync metal parts. It was both expensive and time-limited, because after less than a year the new GPU began showing same ill behavior.įirst and foremost: CLEAN thoroughly the heat dissipation system. I have the same issue, for the second time.Ī year ago I had to replace the failing Graphics board (thanks iFixit for the guide). They are over priced pieces of to be quite honest.

Oh, other common problems associated with this model: left side of screen is brighter than the right (bad for graphic designers and photographers especially), the over all screen brightness is WAY too bright for any realistic calibration (without the purchase of expensive software), and the cd/dvd drive is a faulty one mine broke within months of soft use.Īpple sure hasn't left a good impression for this first time mac owner. I should also mention that even with the fan control installed and running, I still can't watch a video without freezing and glitches. Apple should have offered to replace this faulty graphics card, since it is a known issue. The SMC fan control does help, but it's hard to have piece of mind jacking up the fan speeds much higher than they were suppose to be run.

I've had multiple issues with this computer and am quite *#%!#^ that Apple continued to ignore and deny this problem.
