I have chosen everything to get for my custom built pc except what kind of cooling I need, which I was hoping so,Rome could help me with. I will list the specs of my computer and I would appreciate if someone could give me suggestions on cooling. I am really only willing to add A processor cooling fan or some case cooling fans, if anyone thinks I need these could they tell me what kind or how many? Lastly, I already have a processor cooling fan, just asking if I should upgrade to a heavy duty copper
You do not need any additional case cooling for an i5-2500 and a 108W HD6670 assuming the case comes with one chassis exhaust fan on the back and a normal (not passively cooled) power supply.
You cannot OC your i5, so I wouldn't change out the standard Intel cooler unless you are trying for something special like extreme low noise. (or want something that looks nicer viewed thru your case's Side Window).
