I have a Barton 2500+ @ 11x200 using the retail stock HSF and my load temps go up to 54C or so. I am looking for a little extra stability during the summer heat/maybe a little better OC(can get it into windows at 2300 but unstable.) What are some coolers that people would recommend? I have been looking but haven't seen any really recent roundups. My mobo is a NF7-S in case any monster sized coolers have any problems fitting this board.
