I bought ASUS ATI HD 5570(EAH5570) low profile card last week. The card is really loud. I think fan is working with 100% of speed. I tried to access fan settings using ASUS SmartDoctor and MSI Afterburner, but fan control option is not available. I heard about ASUS enhanced display driver, but I can not find it on ASUS website or CD with drivers. I'm almost sure my card supports fan control.
