i have a amd fx-8120 and the cooler is really loud, i was thinking of getting a cooler master 612s cpu cooler, will it fit in the zalman z11 plus, will it fit on the asus M5A78L-M mother board or cover any of the ram slots on the asus M5A78L-M mother board.
I would not recommend it, with a micro-atx motherboard you may be better off with a bullet CPU fan. Arctic cooling makes many silent ones which would suit your needs just fine. If you have low profile RAM it is a possibility. Your case should support the fan and there's a cut out on the back of your motherboard tray with will make it MUCH easier to install.
