Back to the silent base line after a few years
A few years ago (2020), I built a PC with a Core i9-9900 processor in a Silent Base 801 case, with three additional 14cm Pure Wings 2 fans and a Dark Rock 4 CPU cooler. I was thrilled with the setup until I sold it. Since then, I've gone through countless cases, coolers, and fans from various brands, always good quality ones like Fractal, Noctua, or Thermalright. For the past few months, I've had to deal with a setup that runs quite hot: a Fractal Pop Silent case, a Thermalright Phantom Spirit 120EVO cooler, and three Thermalright TL-K12 fans. No matter how much I adjusted the fan curve and PBO values of my 9800X3D, I couldn't get it below 60°C at idle, and the fan noise was quite annoying. So, when I'd had enough, I went back to BeQuiet!, bought a Silent Base 802, eight 14cm Pure Wings 3 PWM fans, a Dark Rock Elite CPU cooler, and, since I found a good deal, I also upgraded my power supply to a 1200W Dark Power 14 (In 0db mode). i'm in love and comfortable with my setup again. I have the case fans set to level 1 (500 RPM) and the Dark Rock Elite in silent mode. Now I have an idle temperature of around 48°C, while gaming and pushing it a bit, it doesn't go above 65-70°C, and in stress tests, it doesn't exceed 84-85°C. All this with the solid/silent panels; I haven't used the mesh ones. For security reasons i have setup thermal limit to 90ºC in bios, with MSI Enhanced Mode 3 PBO settings.
After all this tinkering, I just wanted to reiterate that one of the best options has always been silent bequiet cases (in my opinion, they should be as quiet as possible), which offer excellent airflow, plenty of space, and exceptional quality, as well as fans and heat sinks.
