My motherboard is Asus M4A89GTD Pro USB3 and Processor AMD Phenom II X4 955 Black Edition . The stock cooler temps are ok but the noise of the fan under load is too loud so I'm looking for a cooler under £30 that will go on my board , my case is a xigmatek utgard so I can access the rear of the board without removing it from the case , any advise welcome as I have never fitted a cooler myself
