There could be another reason other than it being too warm for this chick to be drinking a lot of water. Have you checked the crop? Sometimes an impacted crop will cause a chicken to drink a lot of water.
Is the chick extending its neck and doing a swivel motion? Is the crop very full and hard? Has the chick had access to appropriate grit? Has the chick been grazing in long grass or other fibrous material?
To be sure about the crop, chick it first thing in the morning before you give the chick any food. If it's not flat and empty, you probably need to treat for a crop disorder.
By the way, your actual geographical location actually provides us with lots of information when we're trying to figure out what could be going on with your chicken.
