Fans for cooling, kit or DIY?

[dmolavi]

My tank is up to about 80 degrees (I like keeping it at 78).

I'm debating purchasing a "purpose built" aquarium fan for cooling, or to just use some DIY solution (small desk fan, etc).

Tank is 40 gallons, 20 gallon sump. I'd be mounting the fan on/near the sump so the DT stays "clean".

Does anyone have any suggestions?

Thanks in advance...

I use and see a lot of folks using computer fans . Can run off an old 12v wall wart and small .

In/around the sump? I've seen folks use them as cooling for canopies...

No difference . You have to look at your situation and figure the best way to do it .

I found this DIY chiller in the picture archive that really gave me a idea of making one.
this member had a idea that can work for all of us job well done,
I think the only thing I would do different is use a block of ice made from a milk jug with a hole drilled through it so the water hose can run through it.
instead of a ice pack just resting on the hose .

this really utilizes the cooler the fish are shipped in
always wondered what I'd do with all them coolers besides for storing stuff
in .

Here's a video on a DIY USB fan that the author claims to have had good results with.

I bought the parts myself, but can't figure how to affix them to the tank. Tried velcro, but the fan pulls away.

80 isn't bad at all. Using fans on sump is going to cause more evaporation. If tank isn't going above 80-82. I wouldn't worry about it. " if it ain't broke don't fix it"
