They are not cool. The sunspots are not has hot as the rest of the surface, but they are still extremely hot.
These are called sunspots. These are the cooler darker areas on the sun.They range in size from 800 to 80000 km in diameter. They have very strong magnetic fields that can affect radio communications on earth. They follow an eleven year cycle called the sunspot cycle.
As strange as it is to think of a body as hot as the sun having such a thing as a "cool" spot, it actually does! These areas are known as sunspots. Their number changes from year to year and they appear darker in color when studied by astronomers.
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.
What is true about sunspots
Sunspots appear dark in color because they are cooler than the surrounding areas on the Sun's surface, which are much hotter. The cooler temperature of sunspots is due to magnetic activity inhibiting the flow of heat from deeper within the Sun.
Sunspots. They are only "cool" relative to the rest of the Sun.
The dark spots on the surface of the sun are sunspots. They are caused by intense magnetic activity which stops convection and causes a relatively cool spot.
Sunspots are dark spots visible on the sun that are caused by intense magnetic activity and causes the area where the sunspots are seen to cool the temperature at that area.

Sunspots are cooler regions on the surface of the sun. Visually, they look like dark circles sporadically dotting the sun, and their numbers change from day to day.

Magnetic fields that dot the surface of the sun are known as sunspots. Although they are hardly cool in temperature, they are much colder than surrounding areas, which causes them to be visible as darkened spots.
