Hey PCPP, I posted version 1.0 of this build about a month ago and I was overwhelmed by how many comments/likes it received and I was surprised that it even got featured on the site. I was already working on upgrading the pc when I posted it and I finished building it about 3 weeks ago and have been using it since then and I love every second of it.
Main component changes from ver. 1.0 to 2.0 are ATX system: - CPU i7-8086k -> i9-9900k - GPU 1080ti sli -> 1080ti - RAM G.skill RGB 3000mhz -> G.skill Royal RGB silver 3200mhz CL16
ITX system: - CPU 2700x -> i7-8086k - MB Strix B450i -> Strix z370i - RAM G.skill RGB 3000mhz -> G.skill Royal RGB silver 3200mhz CL14 B-die
I thought about upgrading to z390 Maximus extreme or Godlike MB but since I've already bought all of water cooling parts including 2 monoblocks back in October I decided to stick with Maximus X Hero MB and Z370i MB. I thought it would be cool to have 2 monoblocks in a single system for both looks and VRM cooling performance. I also went with all EK water cooling parts such as fittings,pump, tubes, fluids, and radiators.
AFAIK, Bykski is the only company that makes 2080ti Trio waterblock and I was a bit skeptical but their products turned out to be pretty decent for the price.
Because I wanted to water cool both systems' gpu's as well I had to ditch 1080ti SLI setup on the main system and go with a single 1080ti and mount it vertically alongside the ITX's 2080ti because there is just no way of mounting one horizontally and other one vertically because they will interfere.
Loop order is Pump->T. Sensor->1080ti->2080ti->BP flow meter->rear rad->atx monoblock->itx monoblock->Bykski T.S->T.Sensor->Top rad->Front rad->Pump
At ambient temp. of 23c, 9900k hit max temp of 67c at 5.0ghz 1.28v and 1080ti never sees over 42c. Water temp stays around 32c. When I play some racing games such as AC or F1 2018 on ITX system while have youtube or twitch videos running on ATX system the 8086k reaches about 55c and 2080ti goes up to 48~49c.
Before I started building this water cooled pc, I was a bit skeptical about cooling 2 VERY HOT cpu's, 2 vrm's, and 2 also hot gpu's with just 5x120mm radiators but after testing/using it for 3 weeks I think the temps are really good and well within my comfort zone.
I'm currently using ITX system dedicated to my racing simulator setup that I upgraded last May. I used to have Thrustmaster TX wheel + Playseat setup but the new Fanatec CSW v2.5 + Rseat RS1 Setup with Alienware AW3418DW monitor is such a huge upgrade over the old setup.
Here are some short clips I took yesterday. My desk setup
I haven't been driving on my sim for a while but now the new setup is completed, I just need to put more time into driving. haha
Some might think a dual system is not practical or cost effective and they would rather build two separate pc's and I understand and do agree with them to some degree. After spending about 4.5 months from picturing the system in my head to building two version of it I found both pros and cons of a dual system. But overall, I'm very happy how it turned out. I just wanted to have fun building pc's and that's exactly what I got.
Thanks for looking!
