Thermals
To test the thermal performance of the ECOPC, we measured both internal and external temperatures during four different states: at idle, when playing H.264 video, on CPU load, and on both CPU and GPU load.

The system fan stayed relatively quiet for the most part until the core temperatures in SpeedFan exceeded about 47°C. Once this happened, the fan really kicked into overdrive bringing the noise level up, and the temperatures down. The hottest point on the exterior of the casing near the exhaust fan topped out at only 33°C.

With the fan turned off, the CPU temperature increased by 4°C when idle, 12°C during H.264 playback, and 25~28°C on load. The hard drive also heated up to about 40°C. Temperatures shouldn't reach this high with typical use, but even in a worst case scenario, the ECOPC doesn't heat up enough to cause us any concern. The acoustics of the fanless ECOPC are obviously superior as well, with just the idle whirl of the hard drive generating noise.
Audio Recordings
These recordings were made with a high resolution, lab quality, digital recording
system inside SPCR's own 11 dBA ambient anechoic chamber, then converted to
LAME 128kbps encoded MP3s. We've listened long and hard to ensure there is no
audible degradation from the original WAV files to these MP3s. They represent
a quick snapshot of what we heard during the review.
Each recording starts with ambient noise, then 10 second segments of product
at various states. For the most realistic results,
set the volume so that the starting ambient level is just barely audible, then
don't change the volume setting again while comparing all the sound files.
