The stock CPU cooler from AMD is not used. Thermalright AXP-100 Full Copper (AXP-100R is the closest one I can find in the database for the part list) with a larger fan TY-14013R is used for CPU cooling. The dust filter for the CPU chamber must be removed in my case.
In order to fit the GPU into the case, I have to use a Dremel to cut a small piece of metal in the GPU chamber.
Two 4cm fans are mounted on the top of the case for exhausting the hot air.
AMD 3700X runs at 4.275G@1.25V.
RAM is OC to 3600MHzfirstname.lastname@example.orgV.
The noise from CPU is low and the GPU is silent even under load.
In total, I am really satisfied with my first build ever. The case node 202 is so small but powerful.
Update: Now the RAM runs at 3800MHz-16-16-19-16-36 1.43V.
