Help me create a contraption to mount CPU 120mm fans on a rimless tank.

As the heading says, I need a way to mount the fans on my rimless tank.

Right now I have them placed in a very fragile way, with one edge of the fan over the tank glass and other on top my finnex fixture. This essentially constrains my led fixture placement since I can't move the led fixture in the middle of the tank, where ideally it should be.

Any brethren did a diy before? Pics would strongly help.

Not exactly an kdea of a how to, but have you considered making the mount attach to the finnex light instead of the tank rim?

I hope I'm understanding you correctly- you're trying to fasten fans onto your tank so that it'll bring down the temperature?

This is what I do to cool my tank

Actually I've two tanks. One with the finnex planted plus 24x7 and other (shrimp tank) with finnex stingray clip. The problem would still remain. Moreover, I am looking at a more generic solution that'd work independently.

You understanding is correct but unfortunately for some odd reason, I am not being able to view the pic you posted.

show us how you put it currently

did you try using black zip-ties? you can fasten it to the lights probably. Center, towards the rear of it, facing down, if you get it.

Here is how the fans are mounted currently. Note that the light fixture is at about 30% of the depth of the tank.

PVC pipe and fittings are useful
Grab some small diameter pipe, elbows and tees and make yourself a little fan stand, design it the way you want, can spray paint it black so it doesn't stand out too much

You could buy yourself a large L bracket from the home improvement store. Attach the fan to one side of the bracket with screws. The other side of the bracket gets duct taped to the back of the tank or screwed into the wall.

This is what I was saying.

Just use couple of zipties on each fan and you are done. The fans will face down hitting the water. Each tie will go around the fixture and close like a ring, you can join multiple ties to make a bigger ring.



Black zip-tie will conceal well


You could fix two on one-side, but having one on each side of fixture gives stability.


Cheers!

Update:
Couldn't locate acrylic locally so I added a glass slab to support the fans and can now move the led fixture towards the center of the tank. I still can't control the angle of the fans but I guess I am happy with what I have now. It's almost invisible and unobtrusive.

You may also be overworking the angle of the fans. I find it doesn't have to actually blow onto the water surface to cool.
If you are just moving the air over the top of the water so that new drier air is brought in, the evaporation will be the same. My room air can often go down into the 40% relative humidity while the air directly over the tank may be near 80%. So moving out 80% air and bringing in 40% air will give me the cooling needed.
I find it easier to stand the CPU fans vertical on the tank edge rather than at an angle.

sushantV, knowing these fans don't weigh very much, I do have another idea that would likely work for you. Question, do you have some old metal wire coat hangers, wire cutter, and pliers?

Feel free to make a recommendation. I am sure I'll be able to improvise.

This is kinda what I was thinking of. Takes a little tweeking to get the angles right so that the assembly supports the weight evenly but, in the end is should be similar to lifting the light off the top of the rimless tank. Did something like this with computer fans and ended up zip tieing the longer runs on each side to the actual fan body. This allowed me to lift the assembly up as an entire unit.
