The KobraLan Extreme
mini-PC has multiple noise sources, which
include the heatsink on the CPU and the graphics card. During our 2D and 3D tests, the KobraLan Extreme was always rather quiet. We found a considerable
amount noise from the fans located on the cooler Corsair Hydro H100i
which only occured during heavy loads or
the stress-test. Regards the Thermaltake Toughpower 750W PSU we have to say that it is always very quiet, thanks to the fact that there is not much load on the PSU.
The GTX 780 Ti Gaming uses the famous Twin Frozr cooler and in our opinion the card was always rather silent in almost all scenarios we tested. With the fan set to 100%, we measured a detectable noise but not enough to annoy the gaming experience.
