Doesn't use AMD's included back plate

AM4 Installation

Let’s get back to the issue of the back plate. Reeven included their own that looks pretty solid, but the rubber washers put a space between the board and the bracket. This means that the motherboard can begin to bow a tad at the socket. I’ve used plenty of coolers like this before and while it isn’t a huge issue, I still don’t like it. Once the mounting screws are put through the board, 4 white spacers are needed to space the mounting bracket on the other side.

The mounting bracket was also not the best process of securing. There are 4 nuts that tighten on the screws to hold it in place. In order to tighten them down, a small wrench is included. The problem with this is that the handle easily hits RAM or heat sinks around the socket. Other designs I’ve seen have a little socket with a screwdriver slot on the other side to tighten the nuts. I would have preferred this, but at least the wrench wasn’t too hard to use overall.

After that, you can mount the tower to the CPU, but this isn’t as easy as it could be. The straight cross bracket for putting pressure on the base has to be balanced on the cooler. It has notches to make sure it’s in the right spot, but there’s nothing holding it in place. As a result, you have to very carefully place the mounting screws into the holes and line them up into the other bracket. It takes a bit of trial and error to line them up right, not displace the cross bar, and get both sides screwed in. After that though, it’s pretty easy to clip the fan in. The install process is fairly average in my opinion when compared to other coolers.

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.

The Ouranos didn’t too too bad in testing, but it wasn’t much better than average. Even though the cooler pulled a slight lead over the Mugen, the noise levels were quite a bit higher. The LNA does a great job of curbing the fan decibel level with only a minor bump in temps. Considering the size of the tower though, I was bit surprised we didn’t get a little more cooling performance. On the other hand, I didn’t have a good number of 140mm towers to compare to directly. Let’s go ahead and see if we can find a good fit for Reeven in the computing world though.
