Wall ventilator fan,do they make a big difference heat wise?

[sanook 1]

We have a storage room in the house that gets very hot sometimes. There is no ac or Windows(and dont need also). Thinking about wall ventilator fans,would it make a big difference? One ventilator fan to blow the air out only,or 1 for outside air in also(2 fans total)?

You are planning on cutting holes in the exterior walls? 

 

How many floors is your home, and what floor is the storeroom on? 

 

What kind of ceiling is in the storeroom? 

 

I would probably just go with a louver door.

Thank you for reply.

 

Yes plan to cut holes,thin blocks.

 

This room is ground floor,3 walls are to the outside.

 

Its plasterboard on the ceiling. Block walls.

If that does not keep it as cool as you like, I would install a ceiling fan with a light.

If you already knew, why did you ask? 

 

I meant a louver door to replace the existing door, not a new door to the exterior.

Is there a ceiling and roof above? can you put in a ceiling extractor fan (heat rises), and/or a wind powered whirlybird extractor
