so i have set up my inline fan . its a 6 inch fan that blows hot air out. and i got a window fan that blows cool air in. its all stacked into one window however. It seem that my room is much hotter now??
before i had the window fan blowing hot air out..

i must admit the window blowing cool air in is quite cold at night time i couldnt stand next to it.

im getting a silencer to attach to the 6 inch inline fan currently running half speed.
i was thinking of getting another 6 inch inline fan to blow hot air out..
it seems too hot in the room. still trial and error.

or should i switch the window fan to blow hot air out and use the inline fan to blow hot air out too?
my ducting is quite long havent cut it. should i cut it shorter?
