I cool the aquarium and the room with a household split air conditioning system. It's good for me, the aquarium, and the fluffy cats. If you're looking for a budget option, you can try using bottles with ice, but you'll have constant fluctuations in temperature, which can stress the fish and corals. A more gentle and smooth method is a cooling system that blows air over the "mirror" of the aquarium. However, an automatic top-off is desirable in that case. A chiller is expensive and will heat the room, so you'll have to cool it as well.

A couple of computer coolers on a timer relay is not a bad option to start with. I used that for 3 years for cooling. They make quite a bit of noise at night in the heat. I recently bought a refrigerator - it has become more comfortable for both me and the aquarium.

A regular room fan helped me just fine; I set it to level 1 and directed it towards the water, which lowered the temperature by a couple of degrees. Naturally, I had to add more water.

The fan is directed at the water from above? I read somewhere that coolers are installed to blow away from the water, or is it only for coolers and in cases with a lid!? And if the aquarium has no lid, should the fan be directed at the water? Is that correct?

I have an open top, I was just directing it tangentially, part of the airflow hit the surface, increasing evaporation = cooling, the efficiency is low, of course, but as a temporary solution, it will do.

Lyosha is absolutely right; you can't come up with a better split than 25 degrees. But with a 95-liter tank and no money, you can put a cooler on the water's surface—the water evaporates, which usually lowers the temperature by no more than 3 degrees, but that was enough for me. For automatic topping up in such an aquarium, a simple two-liter inverted bottle (the principle of a cat's waterer) works flawlessly because there's nothing in it that can break!
