ASUS FanXpert 2 on Z77 Motherboards - Page 2

It's fantastic. (get it?)

Hey Tinate,

Did you ever get an answer from Asus about this re: Sabertooth and other Z77 boards? I finally registered on the forums here (been lurking for a while) as I'm seeking the exact same information as you are regarding Fan Xpert 2. I'm leaning toward an Asus P8Z77-V Pro for a new Ivy build, and one of the things I want is total control of all CPU/case fans in my system.

I have a Corsair 550D which comes with 3x case fans using 3-pin connectors, and also a Noctua NH-D14 heatsink which again has 2x 3-pin fans, so I'm hoping the V Pro can control via voltage and PWM on all 6 fan headers. I want silence at idle and fans ramping up to 100% depending on cpu/mobo/GPU temperature. I don't really want to spend money on new fans since I literally just bought this case/heatsink and they are brand new.

Cheers

My Sabertooth Z77 is controlling all 4 3-pin fans with the CHA_FANx headers. It uses voltage control.

Thanks for the info. So with Fan Xpert2, can you toggle PWM/voltage control by individual header? I'll try to confirm with Asus if the Pro/Deluxe are the same as your Sabertooth as this feature is important to me. Will report back.

What are the temperature sensors that you can link your 3-pin fans to?
I remember my old Abit board where I could link every single fan to any given sensor on the board. E.g. Cha_Fan1 to CPU temperature and nifty stuff like that.
It even worked right out of the BIOS so it was totally awesome.

I'd want to use this for the two AP-15 fans that cool my H70 rad.

No, but there's really no reason to use PWM if you can use voltage control. In the system, a PWM would be easier and cheaper to generate than use individual voltage regulators on each header as they have done.

You can do that precisely. You can also map it to a percentage of one sensor plus a percentage of another plus a percentage of a third. For example, you could do 40% CPU, 40% Vcore, and 20% motherboard. The tool would do a weighted average and control the fan speed based on that.

Damn, Asus really went all out on the software side with this, and individual VRM on each header. I'll investigate if the Pro has this, if not might even step up to the Sabertooth, although I want a PCI slot.

Would the voltage control/fan xpert2 still work if there was 2 fans on 1 header by using this splitter?

If it worked, will the 2 fans be controlled individually or the 2 fans will be controlled like 1 fan?

Pro has fan xpert2. As far as I know this is a standard feature across all asus z77 motherboards.

So if I buy a sabertooth z77 I'll be able to control my 3 pin fans through the fan tool, connecting them to the 4 pin headers?

First, you'd have to make sure that you're not exceeding the wattage capability of the header. I'm not sure off the top what that would be.
Second, it would be two fan running at the same voltage = same RPM. They cannot be controlled individually if using a splitter.
