My amd fx 8150 has been running hot lately when playing games such as Far Cry 3. It reaches temperatures of 70 so i decided to get a new heatsink. The stock one is also very loud.
Im planing on getting this one:http://www.newegg.com/Product/Product.aspx?Item=N82E16835233082&Tpk=xigmatek%20gaia%20sd1283&IsVirtualParent=1
but i dont know if it will function any better than the stock cooler that came with my 8150 or if im just making a bad purchase. Could i get some advice on what to buy?
