hmmmmmmmmmmmmmmm i understand the logic you want to use - infact i have see a few dells and compaq's use them. what i wouldnt do is put anything over the heat sink! The fan pulls air onto the heatsink to displace the warm air. If you cover this up - this one happen efficiently, if your using rubber tubing - then your nuts! :p

Theoretically - you get a 80/90mm case fan, and use that at full speed... (your case will have mountings for this anyway.... and duct from that onto the heatsink.... you will want to just mount the ducting 'on top' of the heatsink and not over it.... as that will defeat it's purpose!

You could use some largeish plastic bendy tubing come to think of it....
