Hey everyone.

I want to change all of mine fans that I have now.
But, is there any fan that puts air inside the case?

My case is coolermaster master box 5 lite. 3 fans at front and 1 in back.
 
Solution
with case fans there should be a arrow or marking showing the air direction. (in or out). putting fan one way on case...pulls air in...turning it around blows out. you want low fans pull cold air in and higher fan on case to blow out..hot air goes up.
