Hi all, I got myself one of the new i5 27" iMacs a few days ago. So far, I'm pretty impressed. I use OS X for everything other than gaming, and Windows 7 for the handful of games I play (COD:MW2, WoW, Unreal Tourament 3, Assassin's Creed etc) and the ATi 4850 has been able to run everything at native/highest resolution and on full quality settings. I have noticed though that the case gets ridiculously hot. I know they're designed for this, but are there aftermarket cooling solutions available? I'm assuming it would be something like a clip-on bar under the speakers with extra fans or something? Or am I just better off sticking a small desk fan behind the screen to cool down the back/heat sink? Also, is it normal for the CPU to idle with one core at 90-100% and the others at 20-30%? This happens in Windows 7, I haven't checked in OS X yet. Any help appreciated.
