I have an avc as well and thugs fan seems to push same cfm as mine does but mine is running 4000 rpms....So I imagine the db is quite a bit lower then the 33db I think mine is...
I hit 55c under full load at 2.51ghz (157) but this board is running about 4-6c different then the asus p4s333 board...ON that mobo at 2.51ghz idle I was only 39c (5-6c lower then epox) and 52c high...all of that while running 1.775v (1.83V ACTUAL) versus only 1.675v (1.61 atual)...
