materials for ducting?

[Dug]

I would like to duct my side fan (80mm) directly to my CPU fan (60mm). The fans air flow it perpendicular to each other. I tried using a plastic bag and elastic bands but the CPU fan would suck in part of the bag and make a horrible noise, improved temperature though. I need sugestions for making the duct.

Cardboard and duct tape. You gotta love duct tape

You could also use DRYED tubing you know that aluminum stuff. Of course you'll have to cut a big hole to run it through either the front or the side panel.

Cardboard and aluminum duct tape. It's a roll of adhesive backed thin aluminum used in AC work, greAT for ducting out your pc.

Cardboard works well, pvc piping, gutters, coke bottles, etc.

I cut the bottum of a paper cup and put it over the processor can, and taped it secure. My CPU temp went down 1-2C but my case temp went UP 1-2C... whatevers...
