H100i and Phanteks PWM fan controller

[Crucio]

Morning all,

Could I get some help please, I built a new build last night in the Phanteks Enthoo Pro and have a H100i installed in the top with two of the Silverstone SST-FQ121 fans replacing the stock.

At the moment I have the PWM fan controller that came with my case plugged in to the 4pin CPU header and then the two SST-FQ121 pluged in to the controller.

Have a couple of questions about it.

Will I still be able to use the Corsair link software to maintain my fan speeds going though the PWM fan controller?

The fan Controller only has 3 pin connectors, will it cause any issues with the SST-FQ121 which are PWM fans themselves?

Thanks for your time

Thank you for the reply Samy.

I have been reading up as much as I can regarding my set up and your information was useful.

I have noticed a few errors I have made on my build so far and am going to fix them tonight.

My first error is that I made is that I have plugged my H100i fans in to my fan-hub not splitter from the water block. From my understanding I should be able to control these from the link software once hooked up correctly.

On the Enthoo Pro, the front 200mm fan sounds like a Jet plane to me. I need to switch it out asap. To get it down to a normal volume I had to turn it to about 10% speed

There seems to be a lot more to fans and there set up than I thought, like finding out plugging a 3pin fan in to a 4pin header means that it will run at full speed.

My plan for tonight is to:

Replace the 200mm fan with AF140 fans and hook them to the Phanteks PWM header.
Hook the SST-FQ121 to my H100i water-block though the cable that came with it.

FYI this is the fan header that comes with the Enthoo Pro

From what I have read the fan I plug in to the white header on the hub will be used to control the RPM of all other fans connected.

Could anyone tell me if I don't hook a fan to the white header will the fans run at full speed?

Sorry for the rambling post.

As I understand it the white header is electronically separate and different from the remainder and is used to provide a fairly regular tach signal back to the motherboard, which Fan 2-5 cannot.

The 4 pin connector is the one that provides the control. It arrives in the form of a PWM signal.

Leaving the white not connected would not prevent the others working but would leave a 0 rpm signal to the motherboard, which may or may not be a problem.

This info gathered from a picture of the PCB and the components mounted upon it, not from actual use so I could be wrong.

Thank you for the reply Tealc, I am getting my head more round the correct set up i think.

This was the information in my case manual.

Important Note:
1 motherboard connector can only read 1 RPM signal. Therefore, the motherboard
will only read the RPM signal from 1 device connected to Fan 1. The RPM form all other devices will be regulated according to FAN 1. Y-splitter should not be connected
to FAN 1.

So when I have a fan plugged in the hub in position 1 the rpm of that would be the rpm for the rest of the fans in the controller?

Thanks for peoples time.

The fan plugged into fan 1 sends it's rpm signal to motherboard. How motherboard's PWM circuit works determines if it is actually rpm controlled or simply a percent of PWM signal controlled.

If all fans plugged into hub have same rpm range, they will run same speed.

If some are 1300rpm and some are 2600rpm, than the higher rpm fans will run proportionately faster .. both will idle at similar rpm, but as the speed up the speed difference will become more and more up to full speed of 1300rpm and 2600rpm.

Thank you for the reply.


Just ordered 3 new fans (2 intake, 1 rear), the Silverstone FQ141. And will plug these three in to the phanteks fan hub. So as you say they should all run the same speed.

Its gonna be nice to get the Phanteks 200mm fan out, don't know if i just got a dodgy fan but the sound was crazy loud.

Thanks again for the help, will report back if all goes well.

EDIT

The Phanteks PWM controlled fan hub controls 3pin fan speed using the PWM signal from CPU fan header. The speed control is done by software / bios, not a switch on the case. How you control the fan speed curve depends on what motherboard you have and what software you choose.

As the Phanteks PWM controlled hub uses PSU power source, you can plug up to 11 fans. It has a 30 watt load limit. Hub header 1 is master and can only have one fan on it. all others can have splitter .. I believe 2 are provided in the accessories. They were on my Enthoo Primo.

Sorry I missed this post before, really good info here too thanks The motherboard I have for this build is the ASrock extreme6. I know how to alter the speed in the bios and they have a piece of software called A-Tuning which has something in it called FAN-Tastic Tuning which seems okay. Changing in the bios is probably the way to go though right?

Were you using the PWM controlled fan hub to control the 200mm fan's speed?

I was yep, I had it plugged in to header 1. I could only bring the noise of it down when I took it down to about 10% speed in the software.

FYI the software looks like this.

After I had tried that fan test button I was getting the same RPM at 30% that I was at 100%. Can't show my real results as im at work.
