I don't see your point. Maybe it is true for off the shelf stuff. I may assume that a lot of YC readers build their own system. I just build a rack for my desk

I don't see your point. Maybe it is true for off the shelf stuff. I may assume that a lot of YC readers build their own system. I just build a rack for my desk. I have not really put it under load, but I have to see the GPU, Power supply or Case fan spinning yet. For now I only have only once fan for the case. The only fan that moves, but silent is the CPU fan. The only thing that you can hear: The 10 TB HDD.
