>The computers of yesteryear had this little feature known as blinking LED lights .They also had this other feature called noisy disks and loud fans You just described my reasonably current water-cooled PC (except the disks - it only uses SSDs). I have a direct die water-cooled ryzen 7950x and 2x 3090 gpus. Normally my PC is completely silent. The massive radiator surface is fine for passive cooling until about 300W. I can tell the cpu is doing more than usual, because I can hear the water pump (normally I can't hear it - yes I need to add rubber feet, then it'll be silent even when ramping up) in addition to all the hardware monitoring I do. Also leds are extremely important for troubleshooting. Anyone who built an am5 PC knows the pain of "memory training". Having leds on the MB to tell you what is going on is very useful. As for the typical "developer laptop" in my current place of work (and 3 previous ones - all fortune 300 companies) developers use either Windows or Linux laptops. Only managers use macs. How is this relevant? Well, because all these laptops have fans and you can tell when they're busy.
