If you have seen my other post on here the last week, you see that I have been talking about aircon and bought a portable air-conditioning unit (which is great!).
However, when not in use, I am trying to find more economical ways to cool without breaking the bank in electricity...plus, even with AC on and when gaming in my very small room with an overclocked 5950X + RTX 3090, it can get very toasty, lol.
Anyway, I have filled 2 empty 900ml Lucazade bottles with boiled water then frozen them at -15°c and put them in front of the fan, on top of a mini box (positioning could be better) with a paper towel underneath per-use to soak up the condensation. See picture below.
I have measured the airflow temperature (approx 80cm away) with an indoor hygrometer and the temperature of the airflow is actually lower than room temperature by 1.5 - 2.7°c. So not much, but since it's just the case of putting them in the freezer and taking them back out, I'll take it. They last around 2-3 hours depending how hot it is before they turn fully into liquid.
I have seen videos where they tie the bottles to the fan with zipties, but A LOT of condensation builds up on the bottles and drips so I think that would create safety electrical issues dripping down onto the fan, especially if I put them onto the back.

Anyway, any advice on how to make the ice last longer or is there a better liquid I could use? I heard salt water is supposed to be better, but not sure how true that actually is... (If so, how much salt to the water should I add?)
Any other tips or hints are welcome. I am thinking of filling some bottles with holes in the middle and then mounting them, so the airflow around the ice would be better. Image below (not mine):

When I was more into overclocking I had two profiles, one for summer and one for winter gaming so maybe downclock your CPU and GPU and play less demanding/ indie games for a week. Anyway the heatwave is over.
