So it's been a while since my last update.
Since I finished the build back in December it's been great, however whenever I did anything GPU intensive the I'd hear the coil whine from the GPU and it was triggering but I didn't think I could do much so I didn't think about it. Fast forward a few months, working from home continued to drive me crazy and I didn't have a project to unwind, I started looking into it doing a custom loop as another project and thought this would be a cool learning experience. Things started off by playing around in Corsair's Hydro X configurator then I say that JayzTwoCents put out an updated beginner's video guide on how to do it. Similar to my experience putting this build together, everything made sense and I now had a plan on how to do it.
I was apprehensive on taking apart the 3090 because RMA'ing it would have been a nightmare, however with the video from Jay and EK's manual on taking it apart, this was pretty straightforward.
Tube bending was the next thing I was worried about but again, the bending kit I got from Corsair is good for beginners like myself. A lot of trial and error happened but 1 pack of tubing ended up being enough.
I did underestimate the fittings I would need as some of the runs didn't go exactly to plan. Thankfully someone on Reddit pointed me to offset fittings which became a lifesaver for three of the runs and I ended up needing a 90-degree connector for a long run from the GPU to the rad.
Something else I didn't anticipate was changing my front fans. Before I had 6 fans in a push-pull configuration on the NZXT Z73's radiator and wanted to do the same for this, however, I didn't realise until I was trying to screw the fans in, is that you can only screw fans into a Corsair XR5's radiator on one side. Since my case could still support 140mm fans, I decided to switch to them but changed them to Corsair's QLs for aesthetics.
I know I could've made my life easier if I changed to a different case but I still love this case as it's not just a box but I wanted the challenge and I'm still very happy with the results. No more GPU coil whine and temps are great (< 35 degrees doing everyday tasks, no more than 55 degrees when gaming / GPU intensive tasks).
