Fully Silent PCs tested the mighty HDPLEX H5 paired with the turbocharged i9-12900K / GeForce GTX 1660 combo, and things went surprisingly well. The slim (yet heavy) HTPC case managed to keep temperatures around 90°C for the CPU and around 88°C for the GPU. We have to admit that the inside of the chassis featuring 16 copper heatpipes looks even more gorgeous than the outside.
