H110i GT Lower pump rpm below quiet

Is there a way to "force" it to work at a lower rpm?

 

Last time I checked CL4 could not do this, but it should be possible for Corsair to make CL do this as my software can which is how I generated as below.

Could you explain what CL4 is and how i get it to work ?

 

CL4 is short Corsair Link Version 4 and for CL4 to be capable of doing this I expect Corsair would need to add this ability in a future release.

 

It's also possible the pump is "too noisy" as it's faulty.

I have had rattling pumps before. This is not faulty in my opinion. It's just about 300-500 rpm too much.

 

I hope they embed this in the software in the future.

 

The pump is now the "bottleneck" decibel in my system.

I would like that very much. Feel free to link your program.

 

Did you not checkout my home page and I am surprised you did not find http://forum.corsair.com/forums/showthread.php?t=140665 + http://forum.corsair.com/forums/showthread.php?t=137428.

 

If you run SIV in -AIOCTL mode you should exit CL4 before doing this otherwise they will both try and control the CL hardware. I advise you to read http://rh-software.com/Using%20SIV%20to%20Control%20Corsair%20Link%20Hardware.pdf first.

Do i need to keep SIV active in system tray for this to work ?

 

That depends on what you mean by "to work". Does this help?

  1. Once SIV has set the pump PWM % if you exit SIV the PWM % should remain as SIV set it.
  2. If you then run CL4 then CL4 will change the pump speed set by SIV.
  3. If you run SIV in -AIOCTL mode you must not run CL4 for SIV to work as designed.
  4. If in SIV you setup a pump Custom Curve for the pump then you need to have SIV active all the time.
  5. AFAIK CL4 can't use a Custom Curve to control a pump speed.
  6. On my system SIV uses about 5% of the CPU time CL4 uses, so having SIV active all the time rather than CL4 should not be an issue.
  7. SIV is currently using 2.66% of a CPU and looking at http://forum.corsair.com/forums/showthread.php?p=851734 you will see that just the CL4 service used 50% of a CPU.
  8. The reason for SIV using such a large amount of CPU time on my system is that I have 4 x GTX 980 and NVAPI is rather CPU hungry. I suspect it will use less on your system, you should add your PC specs to your profile.

 

BTW did you manage to drop the pump speed using SIV? If not then post the [Link Fans] screen shot.

Yes it did work.

 

How ever. When i set anything below 2350 rpm, the pump sounds like it has alot of bubbles streaming through it. I tried with 2200 rpm ( less air bubbles). Also 1850 rpm, insane amount of air bubbles rushing though the pump. I was afraid i might have destroyed the pump.

 

So i exited SIV and ran CL4 and everything was back as normal.

 

It was worth a try, i guess the pump was designed not go below 2350 rpm.

 

Thank you for letting me try.

Make sure it's not a bubble stuck in the pump causing the noise (neither of my Corsair cooler pumps make any noticeable noise). Try to tilt/invert the unit/PC with the pump running to try and dislodge any bubbles from the pump, that could be your issue, especially if the rad is below the pump.
