This is a quote from another thread:

When a hedgie gets too hot they will splat out on a cool surface. If it continues the hedgehog may stick it's tongue out panting. When a hedgehog is too hot the behavior they exhibit is called estivation. They will become sluggish and move very little trying to keep cool. Some hedgies will attempt estivation as low as 82 degrees Fahrenheit. So to insure that your hedgie remain comfortable it is best to keep the environment they are in between 74 F - 82F to start until you see how your hedgie will tolerate temperatures. Some do well a couple of degrees colder and some can stand a couple higher.

I would just try your best to keep him in that range, and if you feel it getting hot keep an eye on him until it cools down. Definietely keep a thermometer near his enclosure.
