Measurement and Analysis Tools
Our testing procedure involves placing the test system in various states until
temperatures remain stable for 5~10 minutes. The test states are idle, playing
H.264 video, encoding video with TMPGEnc, full CPU load using Prime95 (small
FFT setting), and full GPU loading using FurMark, an OpenGL benchmarking and
stability testing utility.
Temperatures were recording using various software tools and an infrared thermometer on the hottest point of the exterior as well as the AC power draw from the wall.

According to HDPLEX, the H5.TODD can handle CPUs up to 75W but they played
it safe with our sample system, equipping it with the modest Core i3-3225, a
dual core Ivy Bridge chip with a clock speed of 3.3 GHz and a TDP of only 55W.
It's no powerhouse but should be snappy enough for a wide spectrum of users.

The i3-3225 proved little challenge for the H5.TODD, running very cool when
idle or playing H.264 video. It only heated up by an appreciable amount when
both the CPU and integrated GPU were stressed synthetically using Prime95 and
FurMark, a load which generates much more heat than any normal use. Even then,
the CPU temperature did not exceed 70°C while the exterior heatsink remained
comfortably warm. Our real world load test, video encoding with TMPGEnc, was
not nearly as stressful, and the CPU temperature barely topped 50°C. Like
previous sub-65W Ivy Bridge chips we've encountered, the i3-3225 is incredibly
energy efficient, more so than the TDP rating might imply.
