New PC grower

[grow1620]

wow nice design.

I think it will all work out fine..by separating the lights from the grow, you won't need much fan power. Maybe run dual carbon filters on each side of the inline fan, that would help with noise alot too...

nice idea. I wonder.. if 2 filters is better than a filter 2x as thick

Hey nice diagram up there k1net1k!! The setup looks great!

You might want to check out 12vdc centrifugal blowers (80mm - 120mm). They move air at a higher pressure so they dont bog as much under resistance like PC fans do. So they'll push/pull thru a scrubber much better than regular PC fans, and create more negative pressure for your passive intake.
Im ditching my dual 80mm case fan exhaust setup for a little blower(s) like this one --->http://media.digikey.com/photos/EBM-Papst Ind Photos/RL90-18^12N.jpg

Good luck on your project!

Thanks You good people are looking out for me.

OK so if i use a 70HPS will more people talk to me ?

(sorry i should have written "Will i get less hate spam if i choose a different light than cfl's ?")

What? Sorry dude, but most people get where they are by doing their own research. YOU HAVE TO DO A LOT OF READING YOURSELF! Learn how to search the boards and find answers to your own questions. Go to other grow threads and ask questions. People are here to help but posts like that won't get you far...just sayin'.

Who's hate spamming you?

I for one kind of stopped paying attention to the thread after you ignored several questions I asked.

 

[k1net1k]

How concerned are you with noise? Do you want it to sound like a computer or be almost silent?

Hmm, my 'real' PC is pretty loud.

I hope to put it under the desk or in the same room as I am working in. How do I put a dB scale on that ?

 

[k1net1k]

also trying to figure out how to effectively cool lights without any odor leaks. I would think that the best way would be to completely box them inside of some kind of sealed box / duct and not rely on the side of the case for a complete seal. Preferably a glass bottom, and plastic or reflective side panels. What do you think?

I was thinking completely sealed, with some sort of rubber seal for the 2 edges touching the side panels of the PC.

Maybe our goals are different but I'm intending to have zero smell and almost no detectable noise - hopefully not even the sound of a running PC.

I want an undetectable setup also, but noise isn't as important. I would like it to be bearable though.

Which fans are you thinking of running? If possible, you might want to find a case that lets you exhaust your air without the S-shaped ducting as that would add to resistance and noise, but that may not be a problem in your situation.

Yeah agreed, but I have the S shape in the design currently as the inline fan seems to be my best bet. I am looking into any option though.

My requirements.
less than 230mm (8inch) maximum width
Not too loud you cant stand next to it
Able to pull through a carbon filter.

Forgive me for asking, but is there any way you would be willing to post that file on an anonymous file hosting site like http://stashbox.org/ or whatever? I would love to toy with that file since I was planning on making one but don't really know SketchUp yet. Totally understandable if not. Unfortunately neither of us can PM

Sure, ill post it somewhere and you can grab it

rather than using:
80mm fan + long thin "s" type filter
U can make filter with same efficiency:
120mm fan + short wide line type filter

if i'm right U have 150mm space in "electrical" section
U could put filter directly under Ur red exhaust having 120mm fan in carbon scrubber place

 

[k1net1k]

the pc fans in my diagram are just for the light section. there is no carbon filter for that part.

the 'S' shaped bit is a 4inch inline fan, with an elbow pipe on each end to make it sit vertically.

 

[topic]

the whole "S" thing is too big as 4 me...

if U have already bought this inline fan -> do it Ur way...
But i think "my" way is cheaper and more effective -> sorry

 

[k1net1k]

no i havent bought anything yet.

I was thinking completely sealed, with some sort of rubber seal for the 2 edges touching the side panels of the PC.

Okay, so, some background - I'm going to be building a super-stealth (visibly and hopefully audibly undetectable) system in the next couple of weeks. I want to cram as much lighting in as possible but keep it realistic as far as cooling vs noise. SO, we're doing really similar stuff but you have more options for cooling / ventilation, which is great.

The lighting kind of depends on what you're thinking of doing - what are you doing? The best option is a separate upper intake and exhaust for the lighting section, and to have it sealed off from the lower area. I think weatherstripping or a rubber seal can be attached to the case at the point where it meets the glass so that it forms an airtight seal. Keep in mind if you're pulling from an exhaust fan and not pushing with an intake fan in this section, any air leaks will suck unfiltered cab air and exhaust it due to air pressures.

OR, you can just set up a cool tube like Grouchy's and guarantee a sealed and ducted cooling system. Seems a lot simpler and more foolproof.. but you gotta decide on lights first.

I want an undetectable setup also, but noise isn't as important. I would like it to be bearable though.

Nice, you probably have already seen them, but just in case, check out s&p inline fans.

Hmm, my 'real' PC is pretty loud.

Hmm . . if you are going to be running your other PC all the time or don't care about this one sounding like a PC (i want to hide mine in a closet lol) then you have tons of options, so you might want to check out some overclocking forums or the PC fan thread. ~20db is supposed to be pretty much silent, which is around where I'm aiming.

Don't hesitate to get a "louder" fan and undervolt it to quiet it down a bit if you need to.

Yeah agreed, but I have the S shape in the design currently as the inline fan seems to be my best bet. I am looking into any option though.

Hmm, why? Depending on space, you might be able to have it set up to exhaust in a straight line:
|Case|Computer fan||STRAIGHT Duct to extend to|Carbon filter|

Not sure how much width that would take up though. What does SketchUp say, would a 80? 90? 120? fan fit next to the power strip?

My requirements.
less than 230mm (8inch) maximum width
Not too loud you cant stand next to it

If you want visual stealth, check out this case: CHIEFTEC BRAVO BA-01B-B-B. It might be slightly too wide for you, but it's one of the only cases I could find that had a lower intake, and a locking upper door that allows for an upper intake. Most cases would be horribly obvious if you had an upper intake, or require a lot of DIY. Perfect upper exhaust for light chamber, lower exhaust might require very mild tinkering. This would not work for your S-curve ducting if you want a normal back appearance.

THANKS! That will be fun to play with. Sorry if i was a prick when I answered earlier.

Keep it up!

 

[k1net1k]

the purple cylinder is the size of one of the s&p mixed flow inlines i saw. i thought worst case scenario (smell is more important for my stealth) i would use a big fan and good scrubber. i could undervolt it like you said.

that makes me think i should be using 12v stuff (if its powerful enough) and use some fan controllers and PC power supply etc. Im used to working with that stuff.

the width i was thinking of was for a fan. i found that most computer cases went up to about a max of 240mm wide so was looking for fans at least less than that. thats where the 230 came from.

im looking at some of these type fans now too http://www.jaycar.com.au/productView.asp?ID=YX2530&CATID=45&form=CAT&SUBCATID=724

and yeah to do with airflow design, preferably the straighter air path is better, but i need to decide on a fan before i can factor its size/orientation in.

appreciate your comments. hopefully we both have good setups

btw use the arrow tool thing in sketch up and pan around i love playing with that program

The specs on that jaycar fan are a typo - 6.5 inches h2o? lol. Anyway that particular fan is pretty hopeless - 2.4w is nothing but a baby's breath. I would look for a name brand one such as Delta, they make em as loud and strong as you need, and the search on their site is fantastic (can be limited to just blowers, and any other ratings).

If you're aussie (jaycar) I don't think you would find an s&p anyway. The closest I found was the westaflex mixflo (pdf) You can buy them from a "local" hydro store on ebay or other places I suppose. I have the 125 model. They can be used with a speed control, or wired to high or low. I used mine on low and it handled a carbon filter. Overall though, I'd go with a computer fan of some description and I'd highly recommend Delta.

I gotta install sketchup on this pc but when I do I'll check it out. Thanks for upping it.

edit

You can take the fan itself out of the duct caps, I believe.

 

[Moneygrowonweed]

Sweet i love the DIY idea behind it let me know how it works out for you

i dont believe it either, i want to see one in action.

Yeah i recommend delta too (from pc background) still cant help thinking they wont have enough pressure behind them. i guess i just have to try it and see.

And yeah i can get an inline from hydro store or order one i guess

http://www.jaycar.com.au/productView.asp?ID=YX2532&CATID=45&form=CAT&SUBCATID=724 same fan, but with actual specs. slightly larger in size but with more believable stats
