Team Red is back in business!
Got the custom watercooling loop installed, filled, leak tested, purged all out & online w\o issue.
All is working peachy as expected..........
Ran a few sorties in AHIII to heat up the Rx Vega 64 graphics card along w\ the Ryzen 7 1800X to work in the thermal paste that I used that was supplied by EKWB for the EKWB Supremacy EVO CPU waterblock & the EKWB Rx Vega full coverage GPU waterblock w\ EKWB Rx Vega back plate w\ thermal tape (back plate serves as passive cooling plate as well).
With rad fans set for low speed (120mm rear rad fan @ 812 rpms, both front 240mm rad fans @ 737 rpm's w\ water pump speed @ 1712 rpm's) the highest temps on the Rx Vega 64 graphics card reached 58*C @ 1603 MHz GPU\945 MHz HBM2 mem locked at 90 FPS thruout (upper AMD FreeSynch range for my Asus MG279Q Gaming monitor) w\ CPU hitting 62*C (coolant goes thru vid card 1st then thru 120mm rear rad then thru CPU then thru 240mm front rad then reservoir then pump...repeat) w\ Crimson driver & all in-game settings set at max except tree detail (left at default setting level) on purpose to heat this GPU\mem up as much as I could to test loop & all is looking good at this time.
Will be making some fan speed adjustments to get it all optimized as I like then I will record a video of all this running w\ overlay up to show all in operation.
There is no mistaking it, these Radeon Rx Vega series need water to consistently get their max performance.....just as the Fury series did as well (prior graphics card was a Sapphire Radeon R9 Fury X w\ AIO).
Project is now done & complete.......will post a couple of pictures of the loop as soon as I install my spare Belkin 4-port USB hub to my box to download the pictures from my phone (ain't gonna risk using the front 2 USB case ports again....got cable hung the last time). I'm also gonna install a white LED RGB strip along the outer bottom of the PSU shroud to light up the BitsPower flow indicator so I can see it better thru the tempered glass side panel (can barely see it turning thru the red backlighting & red cooling fluid).............
Cross off another task on the retirement bucket list.........................

PS--FWIW, just read GPU\HBM2 mem power draw off HWINFO32 as 218.456 W peak power while playing AHIII.
