Corsair H55 RGB noise and Fan control help?

I installed a Corsair H55 cooler on an AMD ASROCK FM2A85X-ITX motherboard.
Its cooling the 100W A10-6800K CPU well.
But Im not happy with the noise.
Its like the cooler fan is going on 100%.
where should I put the pump and the coolers fan?
There is CPU fan 1 and 2, and a connection for chassis fan.
Should I put the cooler fan and the exhaust fan on the motherboard chassis fan with a splitter?
And the pump on cpu 1 or 2?
I also have a Noctua 60mm exhaust fan.

I think I might have connect4ed wrong.

I connected the coolers 120 mm fan and the noctua 60mm fan into a splitter and into the cpu chassis fan connector,
and the pump on CPU 2.

In Fan Control, I can only regulate the speed of the exhaust fan, while the 120 mm fan is going on 100% and its too noisy for me.
How do I connect this properly?

Help would be much appreciated. I noticed how much I appreciate an almost silent PC.

I'm a bit out of practice, but a few things I would check:

start by removing the fan splitter. You called out three fans (pump included) and according to your manual you have three headers for fans that you can use.

I would wire it up like this:
h55 Pump (4 pin wire) connect to CPU_FAN1
120mm h55 fan connect to CPU_FAN2
60m exhaust fan connect to CHA_FAN1

that should result in your cpu fans scaling with how your cpu is being stressed.

Next I would go into your bios (del, F12 ESC on your BIOS POST Screen) and look and see if you can configure custom fan profiles. If you can, you can tweak them to lower the RPMs to balance out the noise while at idle, while still ramping up when more cooling is needed. Your 60mm fan will likely be the culprit for any whiny noise so focus on that one if you are hearing higher pitched whine.

page 14 here has the manual that I was referencing for where your fan headers are located https://download.asrock.com/Manual/FM2A85X-ITX.pdf

On page 54 of the manual I think this is the root cause:
CPU Fan 1 & 2 Setting
This allows you to set the CPU fan 1 & 2 speed. Confi guration options: [Full
On] and [Automatic Mode]. The default is value [Full On].
Chassis Fan 1 Setting
This allows you to set the chassis fan 1 speed. Confi guration options: [Full
On], [Manual Mode] and [Automatic Mode]. The default is value [Full On].
all three headers are set to a default value of Full On.

If you can, I might leave your pump connection to Full On, set your Radiator fan to adjust with CPU temp and set your case fan to automatic or manually to a lower RPM as long as temps are acceptable.

Also any cable management you can do to reduce the blocks for airflow will help. I see SATA cables, but I am unsure if you are using any. Maybe one 2.5 SSD in the bottom if I am seeing that right. If you aren't using it, you might be able to remove those cables if you have a modular PSU.

Good luck, I hope that gets you to the noise levels you are looking for.
 
Thanks a lot. I tried to follow your instructions now, but now the cpu is overheating. I must have missed something.

I connected the 4 pin connector from the H55 pump into CPU_FAN1. The 3 pin one i left, assuming it is for rgb lights.

The two connectors from the 120mm h55 fan and radiator side are shown in the picture. I chose the slim one and connected it to CPU_FAN2.

But i must have done something wrong. When i go to BIOS, the pc switches off after 10 seconds.

Was i supposed to connect differently?

hmm, well that is quite interesting. let's try something else.

Is the splitter you were using the one that came with the h55? If so I might follow this setup:

Looking at the install documentation https://www.corsair.com/us/en/explorer/diy-builder/cpu-coolers/corsair-h55-h100-h150-rgb-series/ in the section "PUMP AND FANS INSTALLATION"
1. Connect the pump to the 3 pin header, CPU_FAN2 in your case. (4 pin in a 3 pin header is fine)
2. Leave the RGB Header disconnected (upper smaller connector in your last picture.)
3. Connect the PWM splitter to CPU_FAN1 , then connect your radiator fan to that splitter.

Optionally you can also just connect your fan directly to CPU_FAN1 if you are not splitting to anything. The Noctua fan can either connect to the splitter, or leave it connected to CHA_FAN1.

One other note I didn't catch last night, I think your pump be at risk with the orientation of your radiator, see the FAQ at the bottom of the install documentation, under the question "What orientation should I install my radiator?"
Please ensure that the highest point of the radiator is elevated above the level of the CPU pump, regardless of the installation orientation.
If I remember right, this can lead to air in the pump and premature failure.

Last few things to check.

1. when you power on your system put your hand on the pump and feel if a pump is working. it shouldn't vibrate necessarily, but it should be noticeable between powered off and powered on.

2. Check the orientation of your radiator fan, ensure that it is pushing air through the radiator.

3. looking at your case, I see no ability for any airflow to that front mounted radiator. The increased fan noise might be just a result of that cooling setup being starved for fresh air. If you can remove that front panel see if that gets you better temps or fan noise.

I hope that clears up the errors. Good luck!
 
Thanks a lot, I think I understand more now. I connected the exhaust fan into CHA FAN 1, and the radiator fan into CPU FAN 1. They are both rotating.

But I cant feel any vibration from the pump, like you told me to check. I have seen a faint green light, so I think it is connected. One of the pipes coming from the cpu is warm.
But Im suspecting that the pump is not operating.

The front fan is sucking in air through this space in the picture. There is a gap between the front plastic and this metal, so there should be enough air coming in.
.

I have used the pc lying down right now, so the radiator is higher the cpu. I could get rid of the CD compartment and mount the radiator 40 or 50mm higher. Maybe that could help?

But the main problem now seems to be the pump not pumping. How do I troubleshoot it?
