hello, please answer my each questions below. thanks in advance. my sys config pentium D @2.8, 512 ddr2 ram, agp 128mb 5200fx. 1. my case's side panels donot have small holes to help airflow. i have two case fans at the backside one for intake and other for outake.while running my anti-virus scan(i.e. at about 30% average cpu usage) my temps become cpu-53-54, hdd-46-48. so do i need to change the side panels or make small holes in them??? 2. what is the safe temp limits for CPU and HDD under stress like anti-virus scan or playing games? i mean the temp above which i must be careful for my case airflow/system cooling.
