http://www.newegg.com/Product/Product.aspx?Item=N82E16814127284 Can anyone tell me the dimensions of this car in order to verify that it will fit into my HP a17230n desktop PC? From the pictures in Newegg, it looks huge. If you have this card, please tell me some things about it before I buy. I heard that the fan was noisy!: "ATTENTION IF YOUR FAN IS TOO LOUD PLUG THE SECOND PLUG INTO THE CARDS OTHER FAN HEADER THIS UNDERVOLTS THE FAN SLOWING IT DOWN SO IT'S SILENT." Can you tell me what that means?
