Molten Monolith

Description

My monolith rig has been upgraded for desktop use, while I also work on my living room solution.  This is my first attempt at a custom liquid cooling solution, but it seemed to be the most stable for RX Vega based graphics cards.

My trials with the original Monolith are chronicled here.  Monolith

 

After upgrading to an RX Vega, I was having a tough time getting the card to pass the Time Spy stability test using the standard air cooler.  My temps were pushing into the 70C range easily and the throttling of the clock speeds to compensate seems to lead to a few dropped frames.

Online research seemed to indicate that water cooling Vega would yield superior results, and due to the neat builds I've seen on this community, I decided to give it a try. 

 

Using the existing ABS Canyon case I had, and EKWB parts (what my local shop stocks) I have the final product below.

I opted to go for a black/nickel aesthetic.   I had two available 5.25" bays in the upper part of the case. so I went with the EK-DBAY D5 Pump with integrated reservoir.  My case is much taller than it is wide, so there wasn't really room for a separate standing reservoir.  From there, the loop goes Pump/CPU Block/CE 140 radiator/GPU/CE 280 Radiator/Pump.

 

I had to remove the HDD backplates from the lower section to make room for the GPU radiator.  I reinstalled one of the HDD backplates above the PSU.  I also picked up several Noctua NF-A14 industrial fans to push air over the radiators.  I cut a hole in the bottom of the case and added a radiator mount to expel the hot air from the GPU.  I also added a clear side panel, which is plastic right now, but I many try to get some tempered glass in the future.

 

I have a shot of the added radiator mount below.  Not the best quality, but it gets the idea across.  I'll add a picture of the closed up case as well.

I checked the temps on my Ryzen CPU using my previous cooler, the Noctua NH-D15.  Running the CPU-Z stress test and monitoring the temps in Ryzen master, my CPU capped off at 65C at 4 GHZ.  Under the same conditions using the EKWB Supremacy EVO, the temps capped at 58C!  Not too shabby.  I decided to rerun the Time Spy stress test with the new setup changing the Wattman settings on the Vega to 50% power limit increase and 1650 Mhz on the clock and 1100 Mhz on the RAM.

Massive improvement!  I also gave Time Spy a run through as well.

More to come soon, but the Vega GPU temps aren't climbing above 50C right now.  All in all things are looking pretty solid.
