I have my opteron 170 oc to 2.6 on stock voltage and on stock cooler. It idles at like 38. When i prime 95 torture test both cores, it will eventually get up to a max of 65. I know this is pretty hot for stock voltage. Will arctic silver 5 lower it into the 50s for a max, or do i need to buy another cooler. If a new cooler is in order, im kind of poor right now so please recommend one below $30(i know of ac 64 and zalmans)
