HTPC designed to house my hard drives and be as silent as possible. Will be housed in the living room, right next to the 4K TV I intend to play my ripped full blurays, and dvd and access Netflix in 4K. Fans are set at the lowest DC possible without damaging them. They are placed : 1 front, 1 bottom, & 1 back to go for a positive pressure environment to prevent dust intake as much as possible ( since, the computer will be on the hardwood floor directly). When playing a huge 4K video file, the CPU runs at around 43°C, the GPU at 59°C. THE CPU, GPU and PSU are using passive cooling.
