Power & Thermals
Power Consumption - Ambient - 68F / 20C
Power is certainly sipped with our all-out stress test hitting a measly 70W from the wall for the entire system while running OCCT Linpack and Unigine Heaven at the same time.
Our Streamcom FC9 Alpha chassis specifies a recommended maximum TDP of 65W with an absolute maximum of 95W given appropriate environmental conditions. Our 35W TDP Athlon 200GE should be reasonably easy for this chassis to handle.
We’ll start out with an hour long stress test of the CPU cores as well as the GPU cores to give the large aluminum case time to ‘heat soak’. We see a peak temp of 65C with it hovering close to the low 60C range.
With a loop of Unigine Heaven running for 30 minutes on its own, we see a peak temp of 53C with it averaging 50C.
On the CPU only side of the world, we see a peak temp of 50C and it holds pretty steadily right there.
At idle, the case hovers around the 30C mark with the CPU about 32-34C.
This case uses four heat pipes to move the heat to the case walls which are large aluminum heatsinks. No moving parts, no fans, no pumps.
Under full load, we see the case climb to nearly 50C which is noticeably warm to the touch, but not really that hot. The CPU core stays around the same as case +/- about 2C indicating the passive cooling solution is working quite well.
The outside of the case is slightly cooler as the fins are removing heat, but you can pretty clearly see where the contact blocks are on the inside with the 2-3C difference on our FLIR Thermal Camera.
