Stock phanteks front. The rest are Coolermaster RGBs.
Typical gaming 60-70F, GPU mid 60s. For benchmarks/stress test, my CPU will hit 80+.
Probably not but the front has plenty of space
The liquid cooled CPU is very quiet. The only noise if any would be from my GPU fan when playing graphically demanding games such as Mass Effect Andromeda, and only when I'm next to the PC. I normally sit 7-8 feet away from the PC/TV in the living room, and do not notice any noise at that distance.
My receiver is over 10 years old, and it doesn't support ARC over HDMI which would have been the ideal connection. Analog auto output up to 32-bit/102KHZ to the receiver works but volume control from the PC is disabled. Currently, I'm outputting audio via SoundBlaster Omni 5.1 which is working perfectly but limited to 24 bit/96KHz.
I decided to go without them to minimize noise. The current push/pull fan setup with 200mm front case plus 120mm radiator fan is enough to keep the inside temperature at a reasonable level.
The Gigabyte 1080 card barely fits. Because of tight space due to graphic card, mounting Deepcool radiator can only be done with the tubes facing the top of the case. The distal end of the graphic card also touches the case periodically when the GPU fans are on creating rattling sounds, this can be remedied by inserting a small piece of tape or velcro in-between.
