WEIRD IDEA TO VENT HEAT FROM PC TO HALLWAY

Yes hellur! So.. My room is getting just too hot.. So! My idea is to get like.. Some dryer hose lines or something similar thats small enough to work with the rear exhaust fan of my pc case, and have it travel from where its sitting, to my doorway which is about 6-8 feet away, with a fan pulling from the end of it to vent hot air out of the vent line to help airflow. You think normal 120mm fan will be fine in doing that?

no I would get 140mm

please quote me or tag me @wall03 so i can see your response

I guess that could work. Seems interesting

Ye! Got the idea from a self-made soldering station my friend has

Yeah? I might have a 140 somewhere

So you want an 8 foot length of dryer hose laying on your floor to exhaust into the hallway?

 

That is about as ghetto as it gets, if that's how you roll, post pics when done!

Well, I cant afford to run an AC window unit, nor will it fit in my window.. So this is the next step pwp

The problem here would be how much static pressure would you need to be pushing air through what essentially is a long tunnel. Fans able to do that on the PC end would be noisy. 

I'm not saying it absolutely wouldn't work, and I'm no engineer, but I remember leaning about basic fluid dynamics and my brain hurts already.
If we do back of the envelope two plus twos and use a known reference: plumbing stuff.
YAY SMARTY LOOKY ON THE INTERNETY TIME 🙃

A 120mm fan is 105mm in diameter from blade tip to blade tip, more or less 4 inches. YAY DUMB UNITS 🏫🔫🇺🇸 that means you can go get National Pipe Standard airflow loss equations off google. Woohoo.

So basically a good, PRETTY, BEAUTIFULLY BROWN static pressure fan for a hopefully good PC pushes 2.34 mmH2O of static pressure. 1mmH2O is 0.00980665kPa so BADABING BADABOOM you now have NUMBERS. (0.022947561kPa to be exact)

 

So. You put this in the number cruncher for NPS4 (4 inch pipe standard) and a pipe length of 2 meters:

Long story short, 6.50255 e-5 PSI, which I rounded to 0.00007 because I wanted to, translates to 0.00413685 kPa and we've established that a good 120mm fan pushes about 5 times that amount.

So your answer is:

YES, IT WORKY WORKY 🎊

I did the math and now I'm tired.

instead of out in the hallway cant you make it so i can go out the window?

it might even be more ghetto that way :D

 

but regarding your setup do you only have 1 exhaust on the system? and how many intakes?

air travels the easiest way so if the pipe restricts it to much it will just pop out of all cracks and stuff on the case.

the bigger diamater pipe you use the less pressure you need to push it so even if you dont have a fan that fits in it a higher diamater pipe will help the exhaust.

you can also add fans inside the pipe to help it :).

also the pipe itself will give off a fair amount of heat.

 

all in all DBX10 seems to have the math down for the pipe

oh god did they just cut a hole in the glass and stick a vent in it? this is the highest level of sin right there.

I have 3 intakes and 1 exhaust. owo So its high pressure set up.

I do.. with a fan pulling in cool air from the hallway..

T H E G O D S S H O W I T S R E A L . But also I am basically doing this.. My PC is just more easily accessed to my door than my window.. Since my bed is under my window, and is farther from where my desk is. Very small room, so i cant re-arrange things.
