I would take out the heating pad. He doesn't have the capacity to understand that he is too hot and needs to move off of the warm spot. Heating pads should only be used very briefly on very low setting in only certain situations. They shouldn't be part of the regular heat setup as they can cause low temperature burns, and some hedgehogs will refuse to leave them causing other issues. Since you've gotten the cage temp higher he really shouldn't need it anyway.
