Sunspots are the visible results of magnetic flux tubes in the Sun's convective zone. If the stress on the tubes crosses a certain limit, they curl up and puncture the Sun's surface. Convection is suppressed at the puncture points, whence the heat transfer from hot surrounded hot areas is suppressed too.
