I have an old case. It has no fans except PSU fan i think. I'm building a new system.
What's the minimum number of fans i need to buy? How should they be set up to create good airflow? Should I have one fan sucking in cool air into the case and one pushing out hot air, or is it enough with one fan? How should these be situated in the case?
I think that you should have at least 2 fans in your computer. Or maybe 3. If it's 3, I would have 1 in the front for intake. I would have one in the back for pushing and one on the top for pushing as well.
Suggestions for fans with great airflow... Corsair AF120. About 20 dollar CAD each.
