Modding and Installation
I decided that the easiest way to mod this cooler for the AM4 socket was to use screws to mount directly to the included back plate. Unfortunately, that’s easier said than done. I started by drilling only two holes in the bottom brackets. This would center the block on the CPU, but the large size of it meant that the edge was in contact with some capacitors on the motherboard. That was too risky for my taste. That meant drilling three new holes.
I got through the first two okay, but I couldn’t get the bottom left hole to work out with a steel drill bit. Thankfully, a friend with a Dremel had the perfect bit to grind right through the side of the hardened steel bracket. With the holes drilled, I used two thin stainless steel braces to help even out pressure on the brackets. The tricky part is tightening the brackets to just the right pressure. With years of CPU cooling experience, I have a pretty good feel for not over tightening the block. I took a picture of the thermal paste to show how small the Ryzen die is in comparison to the cold plate.
Testing Methodology and Results
- AMD Ryzen 1800X CPU
- Gigabyte Aorus X470 Gaming 7 Motherboard
- 2x Sapphire R9 290X Graphics Cards
- Crucial MX500 SSD
- Cooler Master H500P Case
- NZXT E850 PSU
My favorite stress test program is OCCT. I use the small data set to really turn up the heat on my 1800X. Afterwards, I let the the system heat up for 10 minutes to help the cooler warm up a bit. Then using HWInfo, I monitor the temperatures for 20 minutes. I pull the average number once the time is up, and that’s my cooling result. During that time, I use a phone app to monitor 30 seconds of the noise level from a hands breadth away, and use the average number the app shows for the result. If there isn’t a software based profile, then 100% fan speed is used.
Does our modding fair well for cooling? Yes and no. For starters, the cooler tops the chart on cooling performance. Considering we have other CLCs and air towers to compete against, that’s pretty impressive. On the other hand, that fan noise is pretty high. Essentially, the larger block is unlikely adding any cooling performance to the cooler. The fans have slightly higher RPMs and the additional airflow is the most likely variable to increase cooling. The block is no doubt helpful for the larger Threadripper chip, but merely covering the surface area of the CPU is beneficial enough in liquid cooling it seems.
