Hi, I've been out of the gaming and PC loop for a few years, using only laptops. Now that I have my late 2012 iMac (3.4ghz i7 + 680mx + 768ssd), I've started to game again. Dx11 titles like Crysis 2 looks amazing in native resolution on the high res iMac display! However, what are "safe" temperatures for gaming? Playing the most recent and demanding games, its not hard to get temperatures up to 85-88c for the CPU, and 78-79c for the GPU. I know the max temp threshold for the CPU is 105c, but I also worry about stress to the silicon chips with repeated heating and cooling over a longer period of time. Is modern hardware designed for these kinds of temperatures? This is obviously only when gaming, but say one is gaming 2-3 hours at a time for 3-4 times a week during certain periods? Maybe a bit more during a holiday, then some weeks no gaming at all.. It would be great to hear from someone with real knowledge about these things. I would like my iMac to last 5-6 years, this was an expensive purchase. Thanks!
