It's funny, I activated the fan control in my BIOS and my system was MUCh quieter after reboot. It cuts my CPU stock fan RPM's to 1/3 of what it would have been previously, with perhaps 4 C increase in idle temperature. Now I can hear a whining noise that I suspect is the motherboard fan, but it's really nowhere near as loud as the CPU fan used to be which roared like a jet.
Odd. Your using the stock HSF from the 4200X2? That giant heatpipe thing? I'm using the same thing, and mine isn't noisy at all. In fact, the loudest thing in my machine right now is the asus NB cooler (that 9k RPM thing) that whines like a jet engine. After that are the HDD's.
I tried enabling "QFan", but found that it's only slowing down the CPU fan, and has no effect on CHA1 or CHIP fans (which the documentation claims it does.) I also wish the "QFan" allowed full CPU fan speed at temps lower than 51C. (With CnQ, my CPU temps drop to below MB temps.)
BTW, as my first post here, I'll give you an idea of the entire system config:
Asus A8N-E
- stock NB cooler (NOISY!)
Athlon 4200 X2
- clocked to 2.4Ghz via HTT bus at default voltage
- stock HSF
2x1024 corsair DDR400 (2.5/3/3/6)
- running at DDR440 speed at 2.75
Antec Sonota II (using the duct - which works well for me)
NVidia 6600 GT (stock speeds)
- Zalman VF700 Cu (dropped load temps from 72C to 53C!)
CPU temps never get over 49C, and drop as low as 30C when idle.
