Pentium (4th-gen) G3220 @ 3GHz /w iGPU Cooler Master V8 (fan disconnected) 1250W Chieftec 80+ Gold PSU (fan stays off when under 400W - pc uses less than 100W@max) All case fans are off CPU temps 45-62°C I turn it on with my aluminum ssd for maximum performance! Absolutely zero sound. It's weird to be next to it, you are used to hearing noise while near a PC. +And yes the CPU cooler is nearly the size of the motherboard Bonus points for that?
