This is my quiet gaming/workstation PC using the In Win 303 case. Since a couple of years I've had the goal to create increasingly quiet systems - even at full load and taking the Australian climate on board. This is the first one I'm pretty pleased with in terms of thermals, noise and looks.
Cooling Setup - I had a X99 system in this 303 before with top & bottom as exhaust, but that setup had some rather high coolant temps: up to +14C over ambient. In this build, I've used a bottom-up air flow combined with a monoblock to also take the VRM heat away - and this works much better. The back fan helps create a slightly positive air pressure which the 303 needs as else exhaust heat flows back into the case.
OC - The Ryzen 1700 is overclocked with a +0.14V offset at 3929Mhz, with G.Skill memory at 3220Mhz. The 1080 runs at 2088Mhz. This is totally stable under Aida 64. Some benchmark results at these settings: - Cinebench R15: 1701 - Valley: 119.6fps - Firestrike Extreme: 10516
Noise/Thermals - The noise level is 30-32dBA@1m using Vardar F1 fans than run 450-630rpm, depending on load. At full 144fps gaming load, the coolant reaches 8-10C over ambient, while around +2C at idle.
Cooling Parts - Hardware Labs GTS 360 white + XFlow 420 Radiator. EK D5 pump/res + connectors + PETG hardtubing + GPU&CPU monoblock. Aquaero LT6 controller + inline sensors + MPS 100 Flow sensor.
Next - Upgrade to 1080Ti, install / get the Aquaero power break relay to work
