Anyone with Asus P8P67 Deluxe? What to do with the USB 3.0 box?

[OldTechy]

I have them setup as automatic/temp controlled, just did a quick and dirty profile with three temperature/speed points and works as advertised. Originally, I had the Corsair H70 pump connected to the Chassis Header and the fans connected to the CPU header per Corsair's instructions. After reading your post, I started messing around with Fan Xpert and noticed that I could control the pump's speed on the Chassis header and could not control the speed on the CPU header. Switched the connections: Pump to CPU header and Fans to Chassis header and all is well.

Hi ; newby / n00b questions...
I realize this thread has strayed off topic ...

I am trying to digest the info posted here ...
... and I am a little confused .... (sorry )

I just purchased Asus P8P67 ( std / base mdl ) ...
.. and have a few ?'s

1) Can the 4-pin Chassis-Fan header on P8P67, provide regulated control of a 3-pin fan ? ( how ; i.e. what is trick? )

2) Does this ASUS MoBo have a EFI-BIOS or FAN-XPERT setting to switch between PWM and voltage control for the 4-pin Chassis-Fan.
(as was posted in this thread in regards to a Gigabyte MoBo).

3) Does the 3-Pin Chassis-Fan header provide temperature-regulated, variable-voltage control for a 3-pin fan ? ( any special settings? )

& finally

4) any problems with using a ' 3-pin splitter ", connected to the ASUS 3-pin chassis-fan header, to provide variable-voltage to two(2), 3-pin fans ?

thanks for your knowledgable responses ,,

I think most of the P8P67 "basic" features are the same among all models, I'm using a P8P67 Pro.

1. Yes, the 4 Pin Chassis Fan Header on the motherboard can provide regulated control of a 3 Pin fan. No real trick really(I used Fan Xpert to set it up):

a. Connect the 3 pin fan header to the 4 pin connector, lining up the "tab" on the 3 pin connector.
b. Make sure the Chassis Fan "Q-Fan" is enabled in BIOS or using AI-Tuner>Tool>Fan X-Pert.
c. Use one of the ready made profiles in Fan Xpert or create your own. You can monitor temperatures and fan speed while doing so.

2. I didn't see any switches to switch between PWM or Voltage control. Just plugged in 3 pin fan, and enabled it. Please note, that on my motherboard, enabling the CPU fan control did nothing for 3 Pin fans, fan speed remained constant. I could only control the Chassis fan header.

3. According to my manual, "Only the Cpu_Fan, Cha_Fan 1 and Cha_Fan 2 connections support the Asus Fan Xpert Feature". I'm not using the 3 pin Chassis Fan header at the moment, so I can't verify that it works or not; but I would guess that it would. I may try it in the future, just so I know.

4. That depends on the power draw of the Fans used. The manual states "...CPU_Fan connector supports a maximum of 1A (12W) fan power". I can't find any specs for the other fan headers. I am using a Y cable to connect two fans to a single Chassis header; the Y cable I'm using has the RPM sensor wire connected to one fan so RPM is only being read from a single fan on the connector. Nothing has gone up and smoke and I'm not too worried about burning out the fan header.

Take everything I said with a grain of salt. I just figured out I could setup temperature controlled fan speeds with 3 pin fans on 4 pin header last night. I got it to do what I wanted and called it a success.

Hi,

I have an ASUS P8P67 motherboard and a noctua 9B CPU cooler, which comes with two fans and a splitter to connect to one CPU header. But reading up, I keep hearing over and over that you should only connect one fan per header, concern about overloading the motherboard etc. I'm new to this building lark, so I'm wary to go against such repeated advice. I currently have all fans (2 CPU cooler, 2 rear exhaust, 1 front case) hooked up direct to the PSU so I have no fan control. I'll probably have to us a LNA to make them a bit quieter, but I'd prefer to have fan control if possible. Case is a Silverstone LC17 so no option for a front mounted controller.

Noctua (who seem to be a recommended manufacturer) give you a splitter. Why would they do that if it wasn't meant to be used?

The CPU header on my ASUS P8P67 is rated for 12W/1A. The Noctua fans on the CPU cooler are rated at 1.32W each. So a total of 2.64W/0.22A. Even if thats normal power, and they need double on startup, thats only 5.28W/0.44A - still less than half the rated power of the CPU fan header.

I don't see where the concern is, but as I'm new to this I'm wary of going against advice.

Also, they are 3-pin fans so it sounds like only the chassis header can vary them (CPU header requires 4-pin only). Can I connect the CPU cooler fans to the chassis header? It looks like the BIOS fan settings can vary the chassis fan speeds based on CPU temps, so it would act just like a CPU fan would (I'd just leave the CPU fan warning disabled like it currently is)
