Fan Placement on 55gal

[Epiphile]

Ah, I didn't realize you already had an external fogger running.

You may have to try and find a couple of those ADDA fans... what type did you try previously?

just some $3 80mm's I got from a local computer store that specializes in case cooling modifications.

Hm- that's the same type I've run, too, pretty much.

I just thought of something- if you have a spare timer around, maybe shutting off the fan while the humidifier's running (so the fog isn't getting passed through the fan), to come on after the fog's had a chance to simmer down some might help a bit.

start off without ventilation holes in the canopy and see how you sit with temp and humidity first... ventilate from there.

cut the length of the tank in thirds for placement.

drs foster and smith has fan kits if you don't want to wire up pc fans.

also... rubber washers, nuts and bolts... should keep it a little quieter. better fans have better bearings that'll keep them quieter also.

plexiglass and piano hinges make for a decent glass lid that's workable with cutting and trimming for such applications.

i am going to have to completely agree. you're a smart cookie! the one thing i would add is that while a humidifier is running you might want to cut them off for a minute just in case.

lol, beck, are you calling yourself a smart cookie?

when you buy your fan make sure it has two or three ball bearings and says variable speed, also ask for a manual control switch which costs about 10$ and will let you control the speed it should have the same four prong conector as the fans and at least three outlets for extra fans. all you will need is one extra four prong conector to hook to the power supply (red wire power) black ground) yellow not needed, for rpm control when in computer

side note on timers:

woot.com has a good deal on some nice timers today if anyone is interested.

Genius Idea:

So I think I've solved this on. I'm going to put 2 holes in the glass top. Using a heater/dryer duct, U over from one hole to the other that will have the fan mounted pointed down into the tank. All this can be tucked under the light hood and completely out of the "living space" of the tank while still reusing the air from the tank therefor (theoretically) not introducing new less humid air into the system while still provide an air current and proper ventilation.

If anyone is confused or curious at to what this ramble would look like, I'm going to try and work up a 3D model if I can get Solid Works to run on my computer.

now, that's what i'm talkin' bout!
i like the dryer duct twist... excellent!

That's fine thinking- really good work. This is the type of ingenuity we should come to expect around these parts.
