The gaming results did not differ significantly from the torture results. They were overall better.

CPU & GPU Average Clock Frequencies

We have to look at the average CPU and GPU clocks to get a complete picture since higher clocks mean more thermal load, which pushes the cooling system more. If we have two cooling systems with only a 1-2 degrees Celsius difference and a 100-200 MHz difference in the clock speeds of the CPU or the GPU, it is easy to find the best performer.
