Request for comments - Cooling fan installation for my tank

[gp2700]

hi DIY gurus,

Can anyone comment on this idea of setting up a cooling fan system for my new setup ? (Image is TOP view)

Are you planning for lights over the tank too?

If so, this fan placement will block off some of your lights reaching into the tank.

Looks like u placing the fans over the lights to me??

Anyways for me the best way to place a cooling fan is at 45 degrees to the water surface... Cools water best..

Visualize the flow of air from the fan.. Allow gaps on the acrylic cover for the hot air blown by the fan to exit the covers...

This will very effectively take heat from the lights out from the system... Clip on or screw on sidecof glass saves space too.. For me I dun mind the looks.. If u need can get a hood hide the fan

Thanks for the comments so far.

To clarify - I will be using 4 x 120mm blower fans (ripped out from a old server). So the direction of the air flow will be going away from the overflow.

Probably going to use a micro controller to control the speed of the fans - these fellas are quite noisy when fully turned on.

I'm con-currently working on the LED light fixture - this will rest on top of the acrylic splash guard when completed..

Dun place fan blowing downwards!

Place your fan blowing across the water will be good.

yup, i know ... I'll be using blower fans, the air intake and output is 90 degrees perpendicular, not uni-directional as per normal fans. Just that i can't find blower fan components in Sketchup, that's why I'm using normal 120mm fan component in the drawing

You can face ur fans downwards, provided you place ur wave maker at that area surface.

Creating waves that will make a more cooling effect.

That is what i am doing now..

In another way of saying is surface water circulating is a contributing factor.
