cool tube ? extraction

[Opie Yutts]

I tried cooling my cooltubes both ways... ...They were significantly cooler w/ air being pulled through them.

Well then, I guess there it is. I'll take actual examples over theories any day. Thanks.

for some reason i thought there was a little fan built into the end of the hood were the duct starts?

Nope.

And yeah, just plumb them into your ducting, somewhere before the fan.
