Diablo® III

Upgraded to Latest OSX. Fan Goes Crazy!

I have a one of late 2011 imac 27in version with fully loaded video card(6970m with 1meg ram). I recently upgraded to the latest OSX at Blizzards request due to their recent response that patch 1.08 will not support OSX 10.6.

Anyway, after updated to 10.8 the game makes the Imac run incredibly hot. WIthin several minutes(literally several minutes) the fan is blowing full bore and makes feel like the iMac is going to overheat. Physically to the touch the backside of the IMAC is extremely hot.

Dont why this is doing that, as 10.6 never did this. I was able to run full resolution maxed settings on 10.6 and the fan never did this. Never! It does it every time I play now after several minutes.

What is going on? scared to even play now.

System specs:
3.1Ghz i5
6970m w/1024 ram video card
4gigs 1333 ddr3 ram.

27 Imac medio 2011 (HD 6770M / GDDR5 / 512mb).
I have the exact same issue - had my iMac to tech twice (7 weeks in total) and no hardware issues has been located.
Issue: after app. 30-60 min. of gameplay 1 fan starts making noise (clickish sound added).
Only workaround is to unplug iMac from power - 8 hrs. unplug = app. 1 hr. of gameplay.
Sound persists when game is ended. Restarting is not helping.
Several OSX installs and clean installs tried - all resets tried.
RAM (16 GB) and HDD (256 SSD) replaced, nothing has helped.
Issue first appeared in late 2012 and has remained throughout several OSX updates (today 10.8.5)

Cafo, you may wish to take advantage of a currently active replacement program being offered by Apple regarding your 2011 27" iMac. The details are as follows:

iMac (27-inch, Mid 2011): AMD Radeon 6970M Video Card Replacement Program

Symptoms

Apple has determined that some AMD Radeon HD 6970M video cards used in 27-inch iMac computers with 3.1GHz quad-core Intel Core i5 or 3.4GHz quad-core Intel Core i7 processors may fail, causing the computer's display to appear distorted, white or blue with vertical lines, or to turn black. iMac computers with affected video cards were sold between May 2011 and October 2012.

Resolution

If your iMac has an AMD Radeon HD 6970M video card and is exhibiting any of the issues described above, choose one of the following options to arrange to have your iMac evaluated:

Apple Retail Store: Set up a Genius Bar appointment: http://concierge.apple.com/reservation/us/en/techsupport/

Apple Authorized Service Provider: Find one here: https://locate.apple.com/

Apple Technical Support: Contact us for local service options: http://support.apple.com/kb/HE57

Before you go in for service, please back up your data. Learn more about backup options: http://www.apple.com/support/backup/

If the iMac (27-inch, Mid 2011) meets these requirements, Apple will replace the video card free of charge for three years after the first retail sale of the computer.

Additional Information

If you believe you have paid for a repair or replacement due to this issue, contact Apple regarding a refund: http://support.apple.com/kb/HE57

This worldwide Apple program does not extend the standard warranty coverage of the iMac. Apple will continue to evaluate service data and will provide further updates to this program as needed.
