Threadripper at 4GHz with XSPC RayStorm Waterblock

XSPC got us over one of its first waterblocks specifically designed to help handle Ryzen Threadripper CPU's heat while overclocking. We give you a quick unboxing, break down the block itself, and then we look at Threadripper long-term performance. We finally get it dialed in at 4GHz.

Threadripper at 4GHz

When we wrote our AMD Ryzen 1950X and 1920X CPU review, we showed you benchmarks with the Threadripper CPU at 4GHz. As we discussed in that review, we were not able to overclock the Threadripper to 4GHz and it be stable for long periods of time under load. Running for less than 5 to 10 minutes under load was possible, but the cooling system would quickly reach its limits. Some of that was due to our waterblock we were using at the time not being able to shed the heat load quickly enough. You can see this article that shows exactly how we were cooling the CPU. That waterblock was designed to work with older Intel desktop CPUs, so it simply did not have the surface area that it needed to give our Threadripper coverage. When we show overclocked benchmarks in reviews, we generally show you attainable "stable" overclocks on water cooling. I made the exception in our Threadripper review because I felt as though 4GHz with long term stability was surely possible with the right water cooling equipment.

XSPC RayStorm Neo Waterblock

XSPC has a new waterblock coming to market that is specifically built for Threadripper called the RayStorm and RayStorm Neo. XSPC was kind enough to get us a prototype RayStorm to us for testing. You can see the unboxing below and we do show you measurements and we tear the block down as well to show you the coldplate.

The build quality of the RayStorm waterblock looks and feels to be topshelf. Keep in mind this is a prototype unit so it is possible that design changes could be made between now and the time it comes to market, however the RayStorm feels like a mature product, and certainly this is not XSPC's first foray into waterblocks for Intel or AMD.

As noted in the video, we did run into an issue with one of the mounting posts having a damaged thread that could not be fixed. So do take note that we used our own mounting hardware to secure the RayStorm. We did use the tension springs provided with the RayStorm, so our mount for all intents and purposes should be "identical." If you are thinking about making your own mounting system for Threadripper cooling, the mounting points on the TR4 socket use a m3.5 thread pitch.

The markings on the tubing showing flow are not correct. We did make sure the flow direction is proper.

The mounting system that was provided looked as if it would work extremely well with the TR4 socket. Our first test mount with the system went well. Below is a picture of the mating surfaces after we were done with our testing.

Our mounting was far from perfect, but we did get good mating over the actual dies on the Threadripper. While working with the system the RayStorm block could unload the CPU's heat near instantly. I am going to try some other TIM installation methods and see which one works best for us.
