The Asus had the black fan. If you look closely- the plain 5800 and the new 5900 Ultra has the extact same fan. The noise should be equivalent- which is low.
The place I bought the 5800 is offering to give me a full refund towards the new evga 5900 Ultra- it's tempting.... I don't know if I can do it.
