Moved away from my trusty beQuiet! Dark Rock TF cooler to this new AIO water cooled setup. So far so good. I'm cooling an AMD Ryzen 7 5800X. Idle temps according to core temp are around 34ºC but the Asus Utility reports 31ºC at idle. I ran 2 passes through Cinebench just briefly to see how load temps looked and they seemed steady at 71ºC (according to core temp).
I used Noctua NT-H1 Thermal paste, although I see that NT-H2 is available now. Not sure if I should have stumped for the newer variant.
I have the setup quite silent. The x3 case fans (also Silent Wings 3) are about 600rpm each at idle and the CPU fan (x3 rad fans) are reporting in at 800rpm currently. I also have the pump duty cycle set lower in the BIOS. Default seemed to be 100% all the time no matter the temperature. I've changed it to run ~60% duty cycle if temps are lower than 40ºC, and then something like 75% if temps are lower than 60ºC and finally 100% duty cycle if temps reach 70ºC or above.
So there is room for tweaking if the temps are a little high but my initial feeling is 34 - 71 is a perfectly good operating range.
Ended up having to convert the case to an "open" standard as the radiator wouldn't fit nicely, it touched the heatsink on the VRM so I wanted to use a locating slot further off the motherboard but it was blocked by the upright in the case. So that had to come out... and a screw rounded! So had to drill it out. What a nightmare.
