dual CPU duct??

well i think its time for me to build a duct and since i like making new things tell me what you think about this idea:

first thing to know is that i have a slot 1 cpu w/ a gorb HSF on it
second thing is i have a 120mm intake fan mounted on the side of the case blowing indirectly onto the HSF
third the gorb fan pulls air from above it and pushs it out through the fins on its sides

the intake duct would fit over the fins of the gorb with a tad of airspace around it (i'm thinking tacks in the duct would act as standoffs) and would curve to face the 120mm fan (so it gets the "freshest" air) this duct would also have 2 holes cut into it- a small one on the side facing the mobo to let air get to the chipset and a big one on the opposite side for the exhaust duct

the exhaust duct would as mentioned attach to a hole in the side of the part of the intake duct that covers the fins and would make a somewhat sharp 90degree turn to get to an 80mm exhaust fan at the rear of the case. also the end of the exhaust duct that attachs to the intake duct would have a reduced diameter (i plan on cutting a few wedges out of it) so that it will fit to that side fo the other duct

i'm attaching a crossecton of this so you will know what the heck im talking about! (please note that it is a really crappy drawing.. the exhaust duct would only have the smaller diameter after making the 90deg turn and nothing is to any kind of scale)

does anyone know if the increasing diameter of the exhaust duct would cause problems with getting air to move through the duct?

also would all the ductwork add resistance instead of streamlining airflow? (the whole reason for the duct is because the 120mm fan and the gorb fan work against each other, and i want to get the hot cpu air out of the case, and into my room :P)

I think it would be easier to figure it all out if you did post a drawing.

I have to say from the onset I don't think covering the fins on the orb is a good idea. I would just duct the air to the top where the HSF can circulate the air the way it was ment to. You will find there are not many supporters of the Orb here. Most will tell you to get something / anything other than an Orb to start. I'll have to admit I do agree with them.

Get us a drawing up and we will give it a look see.

I have played with similar setups in the past. I usually will build the ducting out of thin cardboard first to see if the results are worth the effort.

Getting cool air to the HSF can be nothing but good in my book. I question the effectiveness of the exhaust duct though. As opposed to trying to directly pull the air from the HSF it may be wise to just try and exhaust the general air from the whole area. Maybe from above it as heat does rise. Maybe even a shroud around the HSF would do some good.

Now that you have me thinking I may have to try the shroud idea myself.

what do you mean by shroud? i think thats what i'm thinking of...
my idea is to use the end of the intake as a sort of shroud around the fins with holes on either side of the shroud to vent hot air (after passing over the fins) one of the holes is connected to an 80mm exhaust fan the other is to push a little air over my poor hot chipset (the shroud shouldnt touch the fins either i plan on using tacks to hold it about 5mm off the fins)
or do mean the air wouldnt be able to move both so far and in such a tight space around the fins to get out of the case?

Just make sure NOT to short out your system I did that, and it wouldn’t boot up. I would recommend coating the duct with plastic duct tape (not real duct tape, that metal kind) so it doesn’t short anywhere...

ill remeber that though i hope to use flex ducting i think i could "stiffen" it by tapeing large gauge copper wire on the inside right after i finish making everything fit, of course i have to find flex ducting in the right size which may be a problem

Ya know i have this shroud that i ripped off a gateway system- 120mm side intake to a alluminum heatsync- like a gorb- worked great- gotta find it-
