ASUS FanXpert 2 on Z77 Motherboards - Page 5

post #41 of 95
Thread Starter 
So...

I just realized that I never actually installed Fan Xpert 2. What I was calling Fan Xpert 2 was just Thermal Radar. I've since downloaded the most recent version, but I have a couple of questions for you guys:

1) Is there a way to map the speed of the fans back to a different temp sensor like in thermal radar? It seems it's stuck on 'CPU' temp.
2) Are you guys having problems with your assistant fans in Fan Xpert 2? Mine say they will run at a min of 45%, but when I apply the profile in Fan Xpert 2, they run at 7k rpms. I have to go through thermal radar to apply the profile for the assistant fans after restarting every time. The other fans work fine.

This was a concern i also had. It seems no one really knew if you could use 3 pin fans or not.

After talking to the guys at Asus i finally have the answer.

The Asus Z77 motherboards that utilize Fan Xpert 2 the chassis headers 1-4 have BOTH 3-pin and 4-pin support. I was directed here.

Since it hasn't been mentioned, these bundled fan control programs from motherboard manufacturers don't read core temps--only TCase ("CPU Temp") which is basically a meaningless sensor.

It's fantastic. (get it?)

These are the temp sensors that SpeedFan sees on my board (also applies to my P8Z77-V Pro and Z68 boards). They can be used to control any PWM fan. And I don't have a graphics card installed but it will read the GPU core temp as well:

What if it's not a PWM fan? I'm using AP-15s.

Btw I was wrong about what you quoted. I can do that with Thermal Armor - not with Fan Xpert 2.

"Your board" as in the Gigabyte GA-Z77X-UD3H you have listed or do you have an ASUS P8Z77-V as well?

Because I have a P8Z77-V and under "Advanced" I can't find a chip that lets me control fans or even see the speed readings

I had a bunch of ASUS Z68's, then a P8Z77-V Pro that I returned for a deal on this Gigabyte (about $100).

Yes, I saw your update, Tinate.

SpeedFan controls voltage regulated headers as well. The confusing thing about that is when motherboards have several types of headers, like ASUS Z68's. My PRO/GEN3 had:

1x 4-pin PWM + 1x 4-pin PWM slaved
1x 4-pin VR + 1x 3-pin VR slaved
1x 3-pin VR no, that was ^this one above
2x 3-pin with no PWM or VR.

The confusion I had was about the 4-pin header that had no PWM function at all, then the fact that two headers were slaved to two other headers and could not be controlled alone or separately. Then I was supposed to figure out the confusing-as-hell SpeedFan. It all took forever.

In the Z77 boards, Fan Xpert 2 support both 3 and 4 pins fans. I just watch a video from Asus Technical Sales Rep and he mention that both 3pins and 4pins are supported. They even have a live demo on 3pin fans.

If you want to avoid all this and control all of your VR/3-pin fans from one PWM header you can use a Sunbeam Rheosmart. I would use Speedfan to run things since it's the only software I know of that will read core temps, but I wish there were something more flexible and less confusing than Speedfan.

Also, Speedfan doesn't do different ranges of speed; only max/min RPM based on a single desired temperature. So when you hit that ~60C or wherever you want the fans to spin up, it will simply go to the max speed. You can only smooth things out by slowing the increase and decrease of RPM (2% per second is what I have).

Just wanted to say that I have not been able to get speedfan to detect anything but temperature readings on my P8Z77-V and unless I'm missing something very important, or Speedfan needs to be updated, I would say that it does not work on ASUS Z77 boards.

Hmm.. when you click the Speeds tab, those should be your fans.

The Fans tab is actually your fan headers from your motherboard.

Are those tabs empty?
