hi...

can i put the fan parallel to the water?
or should it be 45 degrees?

[Aeon]

p to you, actually I'm not sure which is more efficient. I'm thinking an angled blowing will exert a bigger force and lift more molecules of water. You just want to increase surface evaporation

Vinz,

Check out the picture Aeon posted. Its almost the same..

[Aeon]

Managed to bring down the temp from 30 to 27-28.

okie...

will try to put it at an angle...
lets c how it works...
if it's better....

coz now i use 2 fans and parallel to the water...
temp around 24.2-25.5....

You're in air-con room?
How you get so low?

no lah...
my tank at dining room and onli 2ft...

i use 2 fans both profantec...
1 of them gt 2 small fans and the other the normal 1 big fan...

dun realli know how i get so low...
but summore i wan it to be lower... :P

is tat temp. good enough for my moss and shrimps...
and i also notice tat my shrimps are inactive and rarely c them...
are the dead?
coz it very hard for me to spot them as 3/4 of the 2ft tank is full of moss....

hi...

any1 knows of a really good lobang for fans?
coz jus now 1 of my fan went scuba diving in the tank... :P

think of having 1 for emergency...
any1 knows?

Sim Lim 5th floor, they have all sorts of fans, forgot the price... $5/ea I think.
I get my PC fans there.
For my aquarium I'm using Coolermaster ball bearing fans $10/ea, crazy! lol!

okie...
mayb do 1 row of fans...hehe.. :P

but i dun understand abt the use of pc things like ATX psu?
is it the metal box thiing?
wat's the purpose?

[Aeon]

To change 240V AC into 12V DC for the Fan and for power.

okie...
thanks...

so how many fans can use for 1 of the ATX psu?

[Aeon]

As many as you can put in, if you connect in series. Each fan has 1 male and 1 female molex connector, just join end to end.

[izzat]

okie...

easy to hear...but guess will be difficult to do it...
but the ATX psu uses main power supply right?
so it acts like an adaptor izzit?

can show me pics on how to fix them up?
also the fans...

thanks a million...

I'll be making an article about it... wait a little! :P

More fans = higher CO2 wastage due to surface turbulence and higher evaporation rate.

not likely to achieve 25.5 degrees in a non air conditioned room using fans alone.
even during rainy season, it would be hard pressed to achieve that figure.
most likely the thermometer is not accurate.

minimal cooling when fan is blowing parallel to water surface.
max cooling when blowing directly onto water surface but surface turbulance is max as well.

more than enough to cover your tank.
each fan uses about 1.5 to 3.6 watts, depending on the fans you have chosen. and the power supply is rated 300w.
fans using 3.6 watts are fast and the noise fans will will drive you nuts. 1.5 watts fans are relatively quiet.
using more fans does not give you low temperatures, the lowest temperature achievable is around 26-27 degrees.

okie...
will be waiting for this article...hurry hurry...

anyway i buy another d.thermomenter today...
c if it reads the same temp...
if so then i'm a lucky person...
