Now returning to your comment, yes the bios fan control is not as great as fanxpert2, as it can overide the bios 20% (cpu header) and 60% (on chasis headers), my current CPU fan is noiseblocker 120mm pwm PLPS, and Noiseblocker desing makes it hard to drop down, they have a rainge of 600-1500 according to spec, but what they dont mention is that the 600 is at 0%, and bios still has a restriction of 20%, but mighty FanXpert2 able to overide this and goes deep down to 0% pwm, amazing. Here is a pic to show you what i mean,
Hi Abula, thanks for the suggestions. I did try using the BIOS fan control; however, I was not able to bring the fan speeds as low as with Fan Xpert 2. The BIOS seems to have some minimum limit for fan speed. Just installing Ai Suite III does not drop the fan speeds, I actually have to run the Fan Xpert 2 calibration tool. Once the fans are calibrated in Fan Xpert 2 the CPU fan will drop from like 600-700rpm to 200-250rpm.
For this is why i recommend you to chose careful the fans if you go this route, the fans that i suggested above have their pwm signal operation from 20%, matching asus bios, so in essence Fanxpert will not drop them much lower than the bios will, around 350 is where the bios will maintain them on silent profile below 40C on the cpu.

If there is no alternative fan control software possible at this time, I will try re-installing my operating system and running all updates, etc. prior to installing Ai Suite III (as you have suggested) or I will try using Windows 8 as well. It's just that I've already setup all my programs and everything; I'd rather not have to redo it all, especially since re-installing may or may not help.
I would probably wait for raja, praz and other people that are more knowledgeble than me to see their suggestions, they know their stuff pretty good, maybe they can suggest something less dramatic than reformating.
doomtop wrote:Well here you chose very nice PWM fans, all those fans are rated to drop by noctua on PWM to 300rpm,
Oh, and the fans I am using are Noctua PWM fans, although it is not possible for them to be identical. The CPU fan is NF-A15 PWM and the case fans are NF-A14 PWM and NF-S12A PWM. Maybe I am not doing something correctly, because the BIOS will not drop them so low as you mentioned.
Noctua NF-F12 PWM 120mm Fan ---> Min. Rotational Speed (PWM) 300 RPM
Noctua NF-S12A PWM 120mm Fan ----> Min. Rotational Speed (PWM) 300 RPM
Noctua NF-A14 PWM 140mm Fan ----> Min. Rotational Speed (PWM) 300 RPM
Noctua NF-A15 PWM 150mm FAN ----> Min. Rotational Speed (PWM) 300 RPM
Since you have good PWM fans already, just test it, go into the bios, go into the fan profiles for the CPU header place silent, and boot up without fanxpert, use anyother monitor tool like hwmonitor and post how are the rpm of your NF-A15, if they are dropping below 400rpm, then you could just get the splitter and connect them all, its only $5-10 to test. All your other fan will not be able to drop as low on chassis fans as there is 60% restriction on bios, but the ones connected to the CPU_FAN header should, so this is more a test to see if you could go the splitter way.
