Asus P8P67 Pro - NH-D14 Fan Control

Somewhat dissappointing indeed. I'm going to hook them up to my spare Lian-Li fan throttler on the backplate.

Might try swapping over the chassis fans over to the cpu fans, though I pressume the feedback loop is controlled by mobo temp for the chassis fans.

It can be auto controlled or set manually in the Asus windows tools. I've set my chassis fans to throttle down to 30% if the CPU temp is under 35c sine this is where it sits if i'm just on the web or something.

Just FYI. The chassis fan one seems to control all chassis fans as far as I can tell, not just one.

My Zalman chassis fans are 3 pin and are throttled just fine. I know this because at idle they are barely audible and at full load i get blown out of the room :)

Wait so you are saying that you can plug 4 system fans (2 3 pin and 2 4 pin) and the motherboard is able to control the speed of ALL of them?
 
Yes it controls all of them, but not independently. In the Asus tools you have the option to set the speed curve for the CPU fan and the Chassis fan. The CPU fan only controls the CPU, and the Chassis controls ALL other fans.

At present my PC is idling so my CPU fan is at 40% and my Chassis fans at 30%. All controlled by the software for the board.

Hopefully tomorrow my other Akasa Vipers will arrive and i can test to see what happens when both PWM fans are being used instead of just the one.
 
That changes everything. Thats totally fine - I don't mind if it controls them all as one. I either want them all on max or all silent etc.

So it controls 2 4 pin case fans and 2 3 pin case fans as if they were one?
 
Ok, I thought I'd better check this before I replied and I'm glad I did!

I can only speak for the Asus P8P67 Pro. I imagine the other boards in the series are the same but without seeing the board I have no real idea.

The P8P67 Pro has a total of 4 fan headers.
1x CPU = 4 pin - Located next to the CPU
1x Chassis = 4 pin - Located next to the CPU
1x Chassis = 3 pin - Located next to the SATA Ports
1x Power supply = 3 pin - Located near the Ram

Previously I only had the CPU and the two Chassis fan occupied. I didn't realise the other 3 pin (power supply) was different but it just wasn't near where I needed it.

In the Asus tools you can ONLY control CPU Fan & Chassis Fan. CPU Fan will obviously change the CPU fan. Chassis Fan will change the 2 chassis fans.

The 3 pin near the Ram marked Power Supply runs at full tilt 100% of the time. It is NOT possible to throttle this fan in the Asus Software at this time. Its not even reading a RPM from it which it was doing when the same fan was on the 3pin chassis header.

Apologies for any confusion. Not quite sure why you would even want a PSU fan header. What PSU these days doesn't have its own self regulated fan?
 
Looks like I'm going to be in the same boat as the OP when I get all the parts for my SB build.

Has anyone any suggestions to controlling the fan speeds of the 2 fans that come with the Noctua ND-D14? Is the only solution to swap the fans for some 4-pin ones, like the OP has? If so, can anyone recommend any good fans? I believe the Noctua comes with 1x120mm and 1x140mm ones.
 
daddyorchips, your only option if you want to control those fans is to get a separate fan adapter which plugs into the 4-pin motherboard header, and changes the PWM signal into a voltage control for the fans. I *believe* OCUK sells one which does this.

Otherwise, just run them at fixed RPM. If you have casefans, it's not like running them lower than your casefans helps noise much anyway.
 
Brilliant - do you know what this adapter is called? I take it it's not the adapter mentioned earlier in this thread, since that looks like it powers three 4-pin PWM fans off one PWM 4-pin header with the help of a 4-pin molex?
 
Without even seeing Dariens reply i went and bought what i thought would alow me to run more fans from the boards and lo and behold i can!

Now i have 2x Venoms powered from this with it connected to the Mobo CPU fan header, 1x venom connected straight into the 4pin chassis header and 1x venom staight into the 3pin chassis header.

All 4 fans now scale perfectly and I have room on that adapter to add another if I needed it (no room or need).

The Molex provides the power while the PWM connector provides the speed to all 3 headers. Works a treat and means that both CPU fans are getting the same signal to speed up slow down.

Now I have my CPU fans set at 30% if temps are under 35c and the case fans at 25% for the same temp. As the CPU temp scales up so do the fans according to the profile i set.
 
That's the thing I was thinking off. :) Glad it worked.

I'm still struggling with choosing between a P8P67 Pro and an ASRock Extreme 4 due in part to this issue - none of the PC Stores in Australia seem to stock these adapters, and I'd really like to be able to control the speed of my CPU fans.

Not to mention the ASRock board has more fan headers in the first place.
 
Hi, i'm having the same problem with my nh-d14 and p8p67 pro. I've just received the akasa splitter cable mentioned but can't work out exactly what goes where. :o I've currently got the two noctua fans connected to the mobo cpu fan header via the noctua supplied splitter.

How about this

Right to set up the PWM Splitter -

1.Connect molex to PSU.
2.The one marked motherbroad goes to CPU Header.
3.The fan thats pushing the air through the cooler connect to the one marked CPU.
4.The fan thats pulling the air through the cooler connects to one marked case fan.
5.Set Bios to PWM.
