TONY said:I took the fan off my Asus mobo and put the Zalman passive northbirdge cooler on and have not had a problem with it, the fan was really high pitched and nasty sounding so the zalman was worth the few quid it costs and then some.
Rednut05 said:Its because Asus developed a fan which they put on most of their mobo's and it goes. So ring up Asus and they'll sent you a new free one.
Mine's bee okay since then.
Old one unclips via 2 holes in mobo and then new one slots on.
