+ Total (United Kingdom):
Build upgrade/modification from an existing set-up. Inspiration from Phanteks' 2018 Computex water-cooling demo; and the desire to have a "silent" system primarily for gaming and general work use.
The CPU was de-lidded (stock TIM replaced with liquid metal) for an approximately 17 degree Celsius delta from stock on the same cooler (my old NZXT Kraken x62); with an tightening of the variance between cores from 7 degrees down to 1.5 (testing was following the recommendations on GNs delidding video for consumer level testing). All of this was running my CPU at 5GHz, 1.328V.
Fan speeds are static at approximately 750rpm on the 6 corsair ML 120 Pros servicing the twin 360mm EKWB PE radiators; with the EK D5 Pump running a static profile at 2000rpm. The system is incredibly quiet even at full load; you really have to stick your head up against the intake to even hear a faint hum. The fans are split into two subsets: Front 3 and Rear single operate as static "always on", with the top 3 responding to loop temperature, but never exceeding the speed allocated to the front 3 to ensure my case's airflow was balanced (mildly positive during low load and approaching neutral at full load).
The watercooling kit is: Phanteks blocks and 220 reservoir, EKWB 360PE rads and soft tubing (for the hidden drain and fill components of the loop) & Bitspower 12mm PETG tubing and fittings (with the aim of bending every angle and only using fittings into the components themselves - all but one multi port fitting in the loop to house a temp sensor at the "start" of the loop).
Most other details regarding the kit chosen and my opinions can be found in my previous build's page.
*Bubbles in the reservoir and blocks have since cleared; these photos were taken almost immediately after the EK Blue coolant went in (24 hours of leak testing made me impatient to share the photos with friends).
**Temps can be lowered even further with a more aggressive fan & pump profile, but the idea was to be as near silent as possible... My old build would sound like it was about to take off to achieve even vastly worse temps for the same clocks.
