Hi i just bought an iMac 5k with i7,295x and I knew that when i bought it that it would struggle to play games due to the 5k and overheat. Anytime I play World of Tanks it starts to overheat as soon as it starts and I don't want that heat next to my screen. I noticed that when I use Parallels and play the game in a smaller window about 1/3 the size of the screen my fan does not even turn on and it runs better. Is this due to less pixels being used or is it that the Parallels is using its graphics emulator? I thought about using a second monitor and then just playing games with it at a lower resolution. Is there anyway this could be done or would it still overheat at 2.5k?
