My Media PC is built with the following:
Case: Rosewill FBM-02 MicroATX Mini Tower
Motherboard: MSI A78M-E35-AMD A78 Chipset FM2 + MicroATX
Processor: AMD A10-7850K APU 3.7GHz Quad Core.
Video card: MSI NVIDIA GeForce GT 610 2GB
It has several fans in it (don't know what kind) but I never hear any of them running. I suspect there's several reasons for this. First, the tower is on the floor and not the bench. Second, I don't game. Third, I don't render video. Just stream video like Netflix or Prime. It also has an extensive music library of wav files and it's connected into my audio system. In all in all it probably just loafs along not generating a lot of heat. So the fans remain on low or probably even off. Maybe I should load it up with something heavy and see what happens.
