Ultra-minimalist DIY build

"I ran Primes95 for 4 hours and it peaked at 78C is that good enough, or bad? It’s a 65W 8-core intel; drops fast to 50C in 30 seconds when Primes95 turned off. First time building my own case and heat solution all in one; I was aiming for 74C when I did my math for building it. It’s one side is all heatsink 170mm x 305mm x 45mm, mounted the motherboard on the heatsink, and used 6 heat pipes from CPU to heatsink, and sandwiched acrylic front via spacers to heatsink."
