Your fan speeds when playing
I'm glad to see people discussing this very game on the iMac as it relates to a question I've had ever since I started considering an iMac once I retire my old 2008 MacPro.
How have you handled your Nvidia fan control needs? I'm using an ATI card and so I have Catalyst CC in Win7; I'm not familiar with the Nvidia equivalent, although I imagine I would be soon enough if I pull the trigger on the iMac.
Specifically, have you had to change fan speeds? Since the iMac only has one fan I wasn't sure if an Nvidia control panel would even give the ability to make changes. I've asked Apple folks at my local store about this, but none of them can give me an answer since they don't have any Bootcamped iMacs in the store. Furthermore, I don't know anybody that even has an Nividia-GPU based laptop, so I couldn't use that as a starting point.
Sorry if I'm threadjacking here. I'm very interested to hear how people using their iMacs for gaming handle the issue of cooling. After seeing the load BF3 put on my GPU I had to ramp up the card fan a bit, so I expected the same on an iMac.
