Cooling....I have one large side fan that blows on the CPU fan. There is one exhaust fan out the back of the case. Computer runs cool. My cooler set up is just above the standard cooler for AMD Phemons. Cost was about $23.00. Stock coolers are fine. Could you imagine the headaches CPU manufactures would create for themselves if stock coolers for their CPU's were subpar? Man, talk about recalls... You will be fine with a stock cooler. These have been working fine on off the shelf ready to go computers for years.
