Small Form Factor (SFF) PCs pack powerful performance into a compact design, but are challenging to assemble. Balancing power usage and heat dissipation with performance is the primary concern when selecting components.

My gaming PC setup. The build components follow the recommended case specifications pretty closely. Assembly was tricky - not much space inside this nifty case. When idle (Windows 11 Desktop), the GFX is at max. 20 Watts and the CPU at 10 Watts and the fans spin up very seldom and at low speeds:

With modern games like "Helldivers II" running at high graphics settings, the GPU alone draws about 200 Watts under load. The ambient room temperature was at 24 degrees celsius for this test.

I undervolted the GFX card and the CPU in order to be able to manage the generated heat - limiting the GFX to 900mV via a custom frequency / voltage curve reduced power usage a lot:

With this setting, GPU power use (again, "Helldivers II") maxes out at about 125 Watts. I limited the fan speeds to 80% max for this case, but still the fans are very noisy. Take a look at the temperature and power use:

Nevertheless a super portable system with the Tenba bag; perfect for the annual LAN party visit!
