I decided with prices falling on AM4 components, to max out my primary system with a Ryzen 9 5950X and 64 GB of Corsair 3600 LPX memory. But since I can not keep from swapping out components on a weekly basis, I purchased a Sliger S620 case with its 5 pop off panels for easy component access and enough CPU cooler height to fit my Thermalright Silver Soul 135. I also used the expensive Thermal Grizzly Kryonaut as thermal paste in the optimistic hope that I will leave the same CPU cooler installed for more than 2 weeks.
This gave me a CPU with a higher wattage draw and heat output than the eight core Ryzen 7 5700G or the 4750G I had been using up to now that could actually tax the Thermalright Silver Soul 135.
One real advantage I see with the Sliger S620 is its spacing for a 120mm rear case fan. With the Thermalright Silver Soul 135 CPU cooler, there is enough space for either a standard 120mm x 25mm fan, or the 120mm x 30mm Phanteks T30 as a rear case fan. The CPU cooler fan and rear case fan were run off the same fan header – ideally as I see it – with matching fans – except for the Phanteks T30 as CPU cooler fan that is too wide to fit this CPU cooler.
I initially fitted the PSU across the case, but for this series of tests the PSU is mounted lengthwise to allow a 140mm side intake fan to be fitted. All case & CPU fans were run at 100% PWM except for the BeQuiet! Silent Wings 4 Pro at 85% of the high speed (middle switch setting) to match up to the RPM of the Noctua A12x25. The Phanteks T30 was set to the performance (middle switch setting) with a maximum 1960 RPM. GPU fans were auto regulated
*For noise readings the sound level meter was placed 30 cm from the left front corner of the case, 19cm high, with the CPU cooler side of the case faced towards the sound level meter in the normal configuration and away from the sound level meter when inverted.
The matched pair of 120mm BeQuiet! Slient Wings 4 Pro fans for CPU and rear case fan at 2057 RPM, 85% PWM had a distinct edge to the sound down to 70% despite not measuring as loud as some other combinations. I have not noted this noise when the Silent Wings 4 fans have been used individually in other installations. The BeQuiet! push pin corner installation is both very easy to use and secure. All other case fans were mounted using Noctua silicone fan mounts.
In a different testing session using the Thermalright Silver Soul included TL D12G fan and a Thermalright TL C12 Pro G as rear case fan, a distinct harmonic pulsing noise was noted above 90% PWM with this combination.
The Noctua A12x25 and Phanteks T30 CPU cooler/rear case exhaust fan pairing work well together.
The 3 Arctic fans – 2 P12’s and one P14 was obviously quieter than the other tested fan combinations by a considerable margin. The 2 P12 fan CPU temperature was 4C higher than the A12x25 & T30 combination, but still under 70C and over 4dba quieter. No fan curve setup required, just plug them in and let them run up to full speed as needed. Also a photo – Noctua Cromax silicone fan corners fit P12's and P14's nicely.
In all of my Thermalright Silver Soul 135 testing thus far in the Sliger S620, the 5950X CPU temperature remained below 70C. I am very pleased as this is the largest CPU air cooler I could envision using.

I added one additional comparison by reversing the case airflow - intaking through the rear Phanteks T30 and exhausting out the side.
Also determined that there is enough space to fit a 25mm thick fan over the Silver Soul 135 on the side bracket:
