The thing with the 90º angle is that (a) angle comes in that shape commonly, and (b) the efficiency like I said. Frowny face, check out the vent thread in my sig.

Oh hell yeah my design is based 100% rip off after reading your thread.

It's impossible for me to explain the desire for 90º but in micro land the efficiency aspect becomes more important. The only way I could come close is to say, think of how much space the fins are taking up at 90*, then imagine them at 60*, there is more fin and less air, thus less efficiency of air to get through there.

either 90* or some curves ?? im going to play with a curved wave.

Kinetic, the 2 bend idea is very good although again, keep it 90* imo. It's probably actually necessary considering the lights will be right up close to it. I'll try holding a cfl right behind mine tomorrow and tell you what I think.

Cool let me know if its good. i dont need 100% light proof, just 90% would be good. I will most likely put some blue leds on the front case for appearance anyway. it will match my other pc then

If your light section is completely sealed from your grow area then you might not need as much air/heat to be evacuated from grow area. A lower flow scrubber setup could work in this scenario because cooling in grow area wont be a problem.

Yeah the area i want to put my lights in would be shaped like a cdrom drive space (all the way to the back of the case), probably taking up 2x slots.

Ive tested airflow using a camcorder sealed inside case recording the flow of a giant bonghit passing thru case LOL. Smoke came from both interior vents at high speed(no scrubber on exhaust yet) I dont have lights yet and dont plan on separating them from grow area but I thought this might ignite more ideas for you (just what you need rite?)

I planned a very similar experiment when i finally build this thing. except i have a crappy webcam.

I havent geeked out this much since I got my first quad core processor!!

me too

the FILTER part is exactly like I tried to say

If U could fit 120mm fans U could slow them down (lower Voltage) and:
-keep same efficiency
-lower RPM make less noise...

i dont mean to butt in cuz im not an expert on the subject or have ne experience with it but have you guys tried a wavy curved approach to the light shield instead of a hard straight angle?
like a stretched S just enough curve to block light smoothe curves to let the air flow better, i always see it as when air hits a hard corner it swirls or rolls keepin that bit of air their for a second restricting the flow, but then again idk im just stoned reading this post =P

 

[k1net1k]

yeah its just easier to find/make angled material instead of waved material.

Hey Kinetic, I just took a look and a surprising amount of light comes out when the bulb is up close to it. Most people would be using this as a cab intake vent down low, where the light has to take a natural 3 bends to get in or out with the V design and I think it's fine for yours pictured except perhaps with the one above the fan controller. If there was a lamp or something near the front of the computer at a low level, the light could get in fairly easily, if you picture it, it has only one bend stopping it between your plants and the external light. So I would probably make a multi bend design for that one. Unless you were going to keep it somewhere dark anyway. The light that actually comes out is not so suss, I think it would look normal to most people when they see a modded computer, they expect to see lights.

The wave idea is not so good in my opinion - there are no solid bends for it to take and the light can get refracted or bounced through easily. Flat black paint is good but it doesn't eat 100% of the light. Good luck.

Edit: you know what, perhaps a simple V for that one, but with an added filter of some type, such as aquarium foam. Normally that wouldn't be such a great plan but thinking about it, I've read that heat shields need to be cleaned of dust regularly. That dust cuts the light output more than you would think, so the filter makes good sense to filter it.

i see what you are saying you would need a few feet of curves cuz it doesnt decipate the light as an angled bend does, im just going to stick a filter sponge like thing near my fans thick enough to block light but not too thick to restrict air flow

yeah if not i will tint it with some led lights on the front

What about something like this? It's just a quick hack of a sketch but I think it might be the best for complete light-proofing. It'd definitely restrict airflow a good amount so the spacing of the baffles and ScrubNinja's V light trap would have to be optimized.

k1net1k, your SketchUp's got nothin' on my MSPaint!

 

[k1net1k]

i have some good ideas, i think ill try them out when the time comes.

for now i need to work on lighting and fans

 

[ScrubNinja]

InducedSerenity, those panels are inefficient when it comes to a micro space although it depends on a lot of factors like how much air you need to pass for one. I reckon you'd be better off with one or the other, and hopefully the diagram explains which other

By the way, any time I refer to my V design, it's generally the prototype. I haven't done any more experimenting but it's entirely plausible that a tweak here or there is gonna improve it. As far as making the Z in the optimal design diagram, it shouldn't be hard. Just butt two angles together and glue or tape, or weld, as I plan.



Hope it makes sense.

 

[k1net1k]

yeah u guys got the idea. i will see how it goes, but my intakes will be this style taking up either 1 or 2 CD rom slots

I know what you mean.

That reminds me, if you are concerned with light you might be able to 'cancel' it out by having an LED fan. I was looking at my q9550 (@3.83ghz) and thought that the blue LED cooler master fans I use wouldn't look suspicious coming out of a PC ( my entire case is blue).



What I was thinking is if you were to put a colored fan near the vent then you wouldn't need as much light proofing because you would notice the LED's over the CFL's. I have never tried it but it seems as though it would work. The only concern I have is how much of the CFL's would you see. If it is minimal then you wouldn't need as many angles and your airflow would be increased.

taking up either 1 or 2 CD rom slots

BTW, it is only a CD rom slot if it has CD rom drives in it (I didn't even know they existed anymore, lol), otherwise it is an expansion slot.

I think i'm gonna try and make a few of those light vents.

 

[ThisBuds4You]

Lots of awesome ideas in this thread guys! I'm diggin it

that was the idea

Call it what you want, Expansion Slot (which to me is a PCI slot), Drive bay, blah blah

I said cdrom because non pc-heads might understand what we mean.

 

[k1net1k]

If you don't mind my asking, do you have a preferance to CFL or HID, and any reasons?

So far im leaning towards CFL's because i can get them easily from hardware stores, and they do decent grows.

I still have a lot to learn about the other light types.

 

[Mk3Jetta]

I'm sure hes asking because with a separate chamber it will greatly reduce the temp of the HID lamp in your cab and you could run maybe a 70wHPS or similar CMH....

..and they can also be purchased from hardware stores easily . HPS, anyway.

@ScrubNinja - thanks.
