i had a sk6 on a 1700+ A for about a year and a half and i had similar temps, an 80mm fan wont do you much good on that little sync becausethe dead spot on the fan is nearly as big as the sk6 (unless of course you devise a shroud for it). I bought a slk 700 and an alx 800 both for 20 bucks (watch the cyberdeals, currently i think theres a decent sync for 19.99) and the alx 800 brought me down around 11 degrees
