"That would reduce the fans work (and their own heat!)"
Years ago, I bought a Shuttle barebones Pentium 4 with a heat pipe, hoping that it would be as quiet as the Mac Minis of the time. It was disappointing. It saved having separate CPU and PSU fans and it was a bit less noisy than the average beige box pc, but still very noticeable.
A problem with heat pipes is that they are not flexible, so the motherboard, case-mounted fan, and heat pipe must match exactly. Not so suitable for do-it-yourself pc building. And in order to reduce noise, you still need to spread the heat over a large surface, i.e. attach a lot of lamellas to the heat pipe, that you could just as well have attached directly onto the cpu cooler.
