Since I relocated to the USA some 5 years ago, I've been without a water-cooling setup this whole time. My old system in Australia consisted of an Iwaki RD20 pump driven at 16VDC mounted in a large custom radiator box that had a 30x24cm radiator facial area pumping to a prototype Storm G7 water-block. That all kept things nice and cool. I brought my PC to the USA, but left the water-cooling behind. Recently I upgraded my PC to an i9-9900K, MSI Gaming X Trio 2080Ti, on a Gigabyte X390 Aorus Master motherboard, all in a Thermaltake View 71TG case. Firstly, this case is a freaking monster! It's dark, beautiful, but it's like the demigod of full size ATX cases, and weighs enough to make the Hulk break a sweat. It also comes with enough mounting capacity to hold two 360 radiators (one in front, one on top), or a 280 radiator in the front and a 420 radiator (eg. http://www.sidewindercomputers.com/thpa420ra.html) on top. Heck, it can support dual 16cm radiators if you wish. Does anyone make those? You want radiators? The case has you covered. So I've always appreciated Swiftech for how Gabriel had looked after me with regards to the Storm G4 Waterblock production, and I know that Swiftech really researches their water-cooling development properly, rather than just slapping together some common designs. I ended up with an MCP35X pump (I had an MCP50X but it was too noisy), the 10cm reservoir for the pump inlet, an Apogee SKF CPU block, and chose the EK full cover block for the video card since it was the only one I could find for the MSI Trio aside from the Bykski one, which just looked to be a straight up copy of the EK one. All together, it looks like the picture below, but I've since re-routed the tubing slightly and am using blue liquid now. I'll post an updated picture once the Iris link for the CPU waterblock LED arrives. Overall, I'm happy. The system is quiet. The C/W of the system with respect to the CPU package temperature is around 0.30, which is a little disappointing, but I'm not blaming the components for this. Rather I believe the bulk of all of that is going to be simply due to the IHS on the CPU, which near as I can estimate accounts for about 0.20 C/W on this particular CPU I own. I'm able to run all 8 cores at 5.1GHz stable, but the CPU is pushing about 225W of heat using Prime 95 on all cores, which is a big ask even for water-cooling to keep on top of. If the CPU could be de-lidded it'd do a heck of a lot better, but sadly this isn't possible with the 9900K's. The GPU core is capable of running at 2050MHz tops, which peaks at 55C under load, but I think I bummed out on the silicon lottery on this own, as it was capable of 2040MHz @ 75C even with the stock cooler. The memory on the card is good though, and is capable of 8300MHz for 3DMark. You win some, you lose some I guess.
