A:Answer This one overheats pretty soon, after 10-15 min on max you'd see CPU and GPU hit 83-85 C and after 87 C the CPU throttles to 3.6-3.7 GHz and 80% utilization ( you can check this simply by running a program like HandBrake and monitor CPU on task manager ). For GPU I use GPU tweak ll (which make a few programs crash) but helps with the GPU overheating and keeps it under 75 with manual fan curve. I'm still looking for a nice third party program to control the CPU fan ( FanSpeed doesn't recognize the CPU for fan curve ). If you game a lot, you can add liquid cooling for CPU and with more effort even for GPU ( you'll find video guides online ). In contrary to what's advertised, this pre-built is not the easiest to upgrade. If you game for short periods of time then you'll be fine using a good fan curve, even with the lousy fans included.
