My case fan blowing in is mounted in the front of the case and i can barely feel any airflow at all...if i un mount it, you will feel alot of air but im assuming thats bad because its just blowing the hot air already in the case. Its a generic fan but i know its not the fan because it blows nice and fine on my enlight mini tower case. The front of the inwin case doesnt seem to have too big of a ventilation or holes to get the air from. What can i do? I have a duron 600 overclocked to 900 and now i am starting to worry about temperatures... also what size fans go in the back above the PS? Any reccomendations?
