I hope this is the right place to post this. I just recently built my own PC and I feel like my system is a little warm or maybe even hot when it's under a load. I use Revit Architecture and 3DS Max to render instead of using it for games.

Here is an image of my ASUS Probe II stats while it is under a load with Revit Architecture rendering an image. When I'm using 3DS Max and rendering, the CPU Temps can even go to 75C or 80C.
I know I should probably buy a new fan other than the one that came with the I7, but I didn't know if I could change any settings to make it run better and cooler.
I'm new to overclocking, so I don't know all of the lingo. Any help would be great!
Thanks,
Stephen
