I'm finding myself on a constant quest to get my lounge pc as quiet as possible, and so far have got it as quiet as I can with aircooling. I have a Freezer 7 CPU cooler, a Zalman GPU cooler, a fanless chipset and a case with to low noise 120mm case fans. I have just ordered a Antec P180 case which will hopefully reduce noise further but I am also considering the Zalman Reserator1-Plus. Does anyone use this or the older model and is it worth the £180? I am happy with the performance of my CPU and GPU cooling so the investment would be purely for noise reduction.
