exhaust duct question

[plizzo]

ok heres my idea/dilemma.
i have an alpha heatsink on my athlon xp1800 and an 80 mm delta fan. since i have the fan blowing away from the hs instead of into it, i would like to make an exhaust duct that just blows the air straight out the side of my case. my plan is to get a piece of pvc that is of equal diameter to the fan and attach it somehow and then cut a hole on the side of my case the same diameter as the pvc and have it exhaust there.
is there a simple way or piece i can use to attach a piece of pvc to the fan? is this idea just plain retarded?
any input is appreciated.
thanks.

well it all sound good

iv never heard of ppl blowing away from hs but thz my fault im not around the cooling forum much

i would think this would be better for u

instead of having it attached to the fan attach it to the case. i dont know how long this is but it is probly long enough[unless u have a wide case] it would also look better

all u have to do is line it up with ur hsfan



a posibly cheaper version [what i have for my front blow hole] is get a insert for a subwoofer box its the exact same thing and u should be able to get it locally cheaper

any way have fun

post pics

good luck

yeah i hadnt heard of blowing away from the hs either until i got the alpha, and blowing out instead of in actually lowered my temp about 2 degrees.
i like the duct there at pcmods and may go for that, the only reason im pursuing the pvc approach is that i have a case made of plexi and found some clear pvc and think it would look real cool if i stayed with the clear motif.
i'll see what i can work out and defenitely post some pics when its all finished.

any other ideas? i'd like to plan it out and do it this weekend.
thanks guys.

Alphas do suck the air away from the HSF, one of the few designed to do so. Having a clear plexi case kind of limits your attachment options as far as having it look decent.

ohhh i see where u commen from maby if u get the pcmods or subwoofer insert[same] then u could cut it realy short and attach the clear pvc then all u would have is the black ring around the hole and a clear tube bhind it

If you are going to use PVC, then I would go to a hardware store and get the compression fitting that is used to hold the drain pipe under a sink.

If someone had a clear case mod, the same thing could be done with chrome pipe for a neat look.

after a little more research here's what i think im gunna try this weekend. i found clear plexi that comes in a square tube. they had a few different sizes, so im keeping my fingers crossed that when i go back with my fan i can get one thats the same width as my delta fan(80 mm). the i'm going to cut 4 little right triangles and drill a hole in the middle of each one and then glue them to the inside of the tube. that way i can put a screw through the holes and screw it into the holes on the fan. then on the other side of the tube i was thinking i could get a square piece of plexi that is a little bigger than the tube and cut a square in the middle of it the size of the tube and glue them together. i could then drill wholes in that and the side of my case and screw them together.

i drew a sloppy pic to help tie all my rambling together.

anyone think it'll work? any improvement ideas?

k, heres a pic thats slightly improved. the square outlined in blue is glued to the tube and screwed to the case.
