Cooling A Tank Down?

we are now down to 26 again

Pointing a fan at an aquarium in an attempt to cool it will have no effect. The air that you are blowing around is still the same temperature. inanimate objects do not experience wind-chill factor.

It does work a little that's why PCs/Laptops have fan cooling?

My room is so jam packed with technology my 24c tank hits 29-30c every night.
I often switch the fan from my PC to my tank, it will manage to get to around 27c but it takes a good few hours.

Proxo i have a similar problem at night, all of them rise slightly but never more than a degree or 2, i have 8 tanks ranging from 1ft - 3ft and my computer all in the 1 room, i tend to have the windows open most nights

The PC fan moves cooler air from outside the computer to inside the casing where the air has been heated by the components to a temperature higher than the room temperature. Your aquarium won't be a higher temperature than the room it is in, so blowing room temperature air at it won't cool it down.

this is like what humanist said, but its on my tank

it takes a while, and a lot of evaporation though

+1, especially since you're trying to cool a warm liquid with a gas warm gas through a thick piece of glass. The cooling that you'd be seeing is purely coincidence and a factor of something else at work. The only way this would do anything is if you were blowing super cold air at the glass at enough of a rate to cool the glass which would in turn cool the water through conduction. The chances of this happening with a fan blowing room temperature air at a piece of glass that is already at room temperature is essentially nil because fans don't cool the air down, they just move it.

Yeah i kinda ment about having the fan aimed at the water surface as that would remove the heat trapped in between the lid & the water, possibly cooling the tank a little or maybe even stopping the temperature to raise anymore.

You have to keep changing out the frozen water bottles. I had a 30 gallon and years back lived in an apartment and we were having a 2 week heat wave where daytime temps were 33-37 degrees C. It was horrible! I had my freezer full of ice packs. I had to go home on my lunch break and change out the ice packs to keep to temp to under 80F. Thankfully the evening temps here do tend to drop quite a lot but then it was back to the ice packs during the day again. Other than that, all you can do is prop open the tank lid so that heat from the light doesn't make things worse, keep the heaters in the tank off and just keep a lot of frozen water bottles in your freezer so you have back up when the ones in the tank melt. You can also do 25% water changes daily but just be careful not to change the temp too much too rapidly as that can shock the fish.

Good luck, hope you get a reprieve from the heat soon!

I hear you on the heat. 40C here today. No reprieve for a month now...
