ASUS P6X58D and Case Fans

Hey guys,

The stuff finally came in. Wow, nice case.

Ok, so my ase has two frontal fans (120), two top exhaust fans (140), one rear exhaust fan (120) and one side fan (120). Note: This is an NZXT Tempest Evo case.

The mother board has the following fan connections:

CPU Fan
CHA Fan 1
CHA Fan 2
CHA Fan 3
PWR Fan

(1)
Only the first three are supported by ASUS Fan Xpert feature, what ever that is. My question is as follows: I have 6 fans, yet the mobo only allows for 3 case fans to be attached and one attachment for "PWR Fan." Should I be attaching any of my case's fans to either the CHA fans or the PWR fan? I'm assuming that unless I connect a fan to the MOBO, it won't have dynamic RPMs.

(2)
Additionally, let it be ntoed that the "CHA Fan 1" has 4 pins, rather than the usual 3 for all the rest. What gives?

(3)
Finally, what happens if I just plug my fans into the power cables coming from the power unit? Do they just fan at 100% speed all the time?

(4)
If I do connect 3 fans, how do I determine whether I should chose the exhaust or intake fans?

Thanks guys,
Daniel

1) Not sure sorry, only that CPU fan is for the CPU fan. :D 

2) Four pins means that four-pin fans can be attached to that fan header and will be able to be controlled by PWM.

3) Seems like it, I've plugged in two 2000 RPM fans tp my PSU which seems to be ridiculously loud.

4) You should place intake fans in the front/side panels of the case, while the exhaust fans should be on the top/back of the case, however if you are talking about which fans to choose, I don't really know/think it matters much.

I have the same board. CPU fan header is only for the processor cooler fan. If you power directly from the PS, the other fans will run full speed all the time. You can use fan controllers to adjust the speed if you use this option(my Antec 1200 case uses this method for all but the cpu fan). You can choose to power from the MB. The designations of 1-3 will just relate to a fan readout in a program like Fan Expert. This is the ASUS fan management software that lets you adjust fan speeds and gives profiles for fan management. You can power 4 fans plus the cpu from the MB headers. So if you use all 6 you may want to get a fan controller (speed control) for 2 of them. Lmeow gave the directions for air flow.

Get 3 of this:

And connect all 6 to the CHA 1,2,3 on the motherboard, 2 fans for each connector on the mobo! This way you'll be able to monitor the rpm of all the fans through windows software (ASUS PC Probe II) which comes with the mobo and adjust their airflow/ noise to your liking.
But you have to check the wattage each fan draws (read the label on the fan) and the wattage each Cha fan connector on the mobo can provide (read the manual) to make sure it can support 2 fans.
About the PWR connector, it's supposed to connect to the fan of the PSU (power supply unit, which is obsolete) and you can use it for a chassis fan to monitor its rpm but I don't think you'll be able to control the speed, i.e the fan will run @ full speed akin to connecting it to the PSU molex directly.
Hope that helped, if you want more detailed info, I'm expecting the same mobo in ~ 1 week, so you'll have to wait, but I already did my research and I'm quite familiar with ASUS

Thanks for the great responses guys.

The manual for the PX58D either doesn't indicate how much fan wattage the MOBO can handle, or I simply can't find it.

Does anyone know how many watts this motherboard can handle for the fans?

1. FanXPert means that the MoBo Utility controls fan speed as you program it. CHA stands for "Chassis Fan" which simply means "case Fan. The PWR fan is for the Power Supply Connection and is left over from a bygone era....when used, it will allow PSU fan speed to be monitored by the BIOS / MoBo utilities.

2. 4 pin means that it's capable of PWM Control

3. Yes, or you could use one of these:

4. I have the Rampage II Extreme and it was listed in the manual (2 amps). Try downloading the PDF version from the web site and searching electronically. "Normal" Case Fans (not the 2-3k rpm kind) are typically rated at about 0.34 amps each. You can gang two of them together on each header as long as you don't exceed the header rating (to be safe and allow for inrush current, I won't exceed 50% of the header rating).

You can use these for CHA 2 and CHA 3,

Use this for CHA 1

1 x http://www.frozencpu.com/products/8418/cab-150/FrozenCP...

.....I'd strongly suggest also buying some heat shrink so that once the cable ends are joined to the splitter, they don't come loose and short out something/ call the frozen cpu folks for advice on sizing but IIRC, I used this:

http://www.frozencpu.com/products/1844/ele-195/38_Blue_...

Of course the PWM header and splitter won't do anything for you if the case doesn't use PWM fans. I'd gang the two front fans together, the two top fans together and the side / rear fans together. NOTE: In my experience (only tried it on 1 build so far), ganging two fans together on an Asus Board results in no MoBo based speed control UNLESS the fans are PWM fans. For that reason, you may want to consider then NZXT Sentry 2 Fan Controller which is $25 .... the cables will cost ya half that but the Fan Controller adds some bling if ya into that kinda thing. Note 2 .... avoid the NZXT LX controller ... read newegg reviews if ya wanna know why.

First and foremost, thank you everyone for your responses. Each has been informational. That being said, I will address this one:

Very cool, I might just grab one because its touch screen and shiny :D

I cannot tell you how much difficulty I've had discovering wattage/amps.

The manual states that the CASE FAN header can support a max of 2 Amps (24 watts). I suppose that's a lot. And I suppose that's good because I have both my 120mm Noctua Heatsyn fans attached to it via splitter.

As for the three case fans, the manual seems to be silent. However, in the case fan attachment diagrams, it states the following in respect to the what each pin on the header does:

Case Fans 2 and 3:
- GND
- +12v
- Rotation

Case fan 1:
- +5v
- Cha Fan In
- Cha Fan Power
- GND

Is that +5v and +12v indicative of a max of 5 and 12 volts, respectively?

Indeed, I've already purchased 3 of these and they are on their way.

It would seem that I could split CHA1, CHA2, CHA3 (which, btw, is currently blocked by my gargantuan HD8750 haha), or disregard all of the above and just purchase the NZXT fan control. It seems like that may be the easiest, and my most likely, step.

Thank you for taking the time to make such a detailed response.
