Top of the line, first water cooling project PC. I use this machine daily for Architectural workloads using CAD, 3D modeling, and plenty of rendering. Also AAA gaming in the evening because why not.
The 7820X was delidded and dropped 15 degrees while on a 360 AIO cooler. This cooler was still pushing temps too high for me and I could only get an overclock to 4.4 GHz with a few cores at 4.6 GHz.
Then I finally bit the bullet for a full water cooling build - focusing on clear, aluminum, and black steel/chrome color scheme. Parts include Heatkiller CPU block and reservoir, highly recommended quality parts!
Issues: Don't do a 280 reservoir up top on the Fractal R6, it touches the RAM and leaves you no room. The bends are not great as it was my first time and I'll be redoing them soon when I get more tubing.
The heatkiller 120mm fan mount didn't work perfectly. The included screws are so short I'm not sure it can attach to anything. I had to tap out the holes just a little bit to allow an M20 screw to go through and attach to the reservoir (used some cut long screws that came with the reservoir).
Comments: The GTR radiator is disgustingly overkill and doesn't work with my fan profiles/RPM. I should have gotten the GTX ... but it was sold out at the time of purchasing and I'm inpatient.
Overclocked CPU to 4.8 GHz and 4.9 GHz on two cores, fully stable!
