This PC has been built for gaming and media purposes. The console-like SilverStone case accommodates the latest Core i-7 Gen9 processor with a 2080 RTX.
Major issue was the cooling solution for a 9700K processor, even with little to no overclocking. The 9700K boosts up to 140W TDP for 20s which is a heavy requirement for such a small case with limited space for a cooling solution.
I tried multiple coolers to get rid of the heat:
ID-COOLING IS-50, which resulted in an unstable system due the under designed heat sink.
Thermalright AXP-100H Muscle, the system now ran stable, but it became noisy.
Scythe Big Shuriken 3 - Similar results as AXP-100H, but the noise has been reduced a little. The lack of ventilation seems to be the major problem when using an air-based cooling solution.
Corsair H55 (AIO water cooling), which runs silent and cool. It's required to replace the provided fan with a low-profile 120mm cooler. For this purpose, I chose the Noctua NF-A12X15 which comes with enough static air pressure. With this solution it's possible to blow the hot air out of the case.
An additional challenge has been the cable management. This small case comes with little to no clips to lay the cables. Due the size restriction it's required to bundle the cables in order to get everything placed and connected.
As high-end graphics card (>200W TDP) I strongly recommend blower editions - otherwise components such as SSDs may overheat due lack of ventilation.
