Im talking about the FanXpert software thats in Asus AI suite. Overview: http://www.youtube.com/watch?v=xaOQ9_pYBYQ
I think it will work with your mobo too. Its a great software utility to control the fans based on the socket temp, much better than any fan controller Ive ever used.
Like I said, if the fans are controlled by the socket temps, most likely the in-built throttling algorithm is too.
In the Youtube video, he doesnt really go into that much on how nifty FanXpert really is. In my case, I have the five mobo fan headers that control 7 fans via a couple of fan splitter. I also, after finding my max practical overclock, have CnC enabled, and have the fans run at the very minimal speed until the the socket temp (which I found is the governing temp (my core temps are higher than socket temps)) reaches 50c and then they run full speed. So, with CnC enabled and surfing the web/watching movies etc, my temps are near ambient and the fans are practically noiseless at about 1.6 ghz. When I start a heavy app that needs the full power of 4.8 ghz,, like prime95, the cpu and the fans kick in before it gets too hot. Other than stress testing benchmarks, the fans rarely rev up.
Back to the original point, you need to get that socket temp down, and decent airflow on the back of the socket can do wonders.
