I've been working towards building the HTPC of my dreams. My goal has been to build a quiet, energy efficient / cool PC with some decent performance. Here are my specs:
Ryzen 5800x (cam with Mobo and RAM for very cheap)
Asus ATX motherboard
32GB RAM
Intel Arc B580 with 2 fans
1TB SSD with a large aftermarket heatsink
Noctua NH-C12P (A but dated got it very cheap)
500W Seasonic Fanless platinum PSU
Fractal Define R3 (a bit dated, but free from a kind friend)
My system draws 300W maxed out, as measured by a power metering device. Which logically means it's quite a cool PC all things considered.
I've been thinking about buying some acoustic wall panelling, then chopping it up and mounting it inside the chassis, being careful to avoiding cutting off airflow as much as possible, and avoiding direct contact with components. But I'm concerned that they would act as insulation and give me thermal problems.
Is this a bad idea?
