Using an AMD phenom II X3 720 processor with stock heatsink, fan's around 2500-3000 rpm/40 degrees when idle. However when on load it goes up to 5000-6000+rpm just to maintain at 55 degrees, which is hella noisy/obvious. I use the cpu resources alot with games on(WOW & others),multiple firefox tabs,msn,music,apps,etc

Was thinking of getting a 3rd party heatsink from lowyat after CNY within the RM150-250 range. Looking for a heatsink that can maintain good temperature(doesn't have to be super low, but good enough so my chip doesn't get damaged in the long run) but most importantly silent so it's not noisy when I'm gaming. Any recommendations for one? Currently thinking of getting CM Hyper 212+ based on the reviews and really low price.
