How to cut 10c GPU temp and 15c CPU temp with airflow ducts

Great, now I just need me a £1.3k 3D Printer and I'm sorted! :D

Seriously though, that's pretty cool stuff. I've done dodgy cardboard ducts before when I had my first powerful computer and had the energy to tinker so much. I don't think it'd make much difference to my current case and would interesting to see the results of this type of custom airflow channels on other cases before trying it out.
 
I remember doing something similar with this...

Having two 60mm and a 80mm spinning at 4200rpm made a proper racket.
 
I did something similar a couple of years ago, but with simple flat plastic sheets instead of 3D printing:

It works well enough that I don't even need a fan on the CPU heatsink.

Servers and OEM PCs use ducting like this too. The downside is that it only fits one combination of case/motherboard/heatsink. Any changes, and the duct might have to be adjusted to fit properly.
 
Watched this yesterday, im sure someones tried this before. That 3D printed Fan dude, i'm sure he's made shrouds like that before to cool the gpu at least.
