What are some cheap methods of lowering the temperature of a 5 gal mash in a 7 gallon bucket with an airlock?

I mean like after 3 to 6 days when you're not supposed to open the lid. The starting temp was perfect and I knew it might heat up here in this very hot climate. Shorts & tshirt today.

sit it in a tub of water,rap some old towels? around it so they are in the water.if that is not enough blow a fan on that.the evaporation will help.

I bought party tubs, like what you pack ice and soda/beer in at a picnic, at costco. 2 for $9 made of Rubbermade soft sided. I put my brew bucket in it and use frozen water bottles to cool it down. More bottles = more cooling or change them out faster. I just bought a case of water bottles from costco and froze them all. In the summer I put fresh bottles in at morning, lunchbreak, dinner, bedtime. Recycle them back to the freezer and you should be fine in 4 hours. Tshirt also works well to double duty as cooling and blocking out light. I use my old black t-shirts for this since it's hell wearing them in 100°+ weather.
