My issue with using iCUE 3.6.109

[_lancemercado]

Hi,

 

First time posting on this forum, but definitely need some assistance with something. I'm not sure if there's someone else out there who've had this issue, but when I installed the latest iCUE update, as well as trying the previous iCUE update, I can't seem to control my H100i v2 fans and pump, as well as, my the LL fans connected to my Commander Pro. I'll attach some photos so that way you guys could see what I'm dealing with. I've sent a support ticket as well and the person who replied gave me a possible solution, however, that didn't work. So currently, I'm using SIV to control all my fans right now.

 

Thank you in advance.

 

Edit: The fan speed on screenshots 2-4 was stuck on that RPM when I was switching between speeds. I don't even think the number displayed corresponds to what the actual RPM the fans were spinning.

First, the default fan curves are based on CPU temperature. At certain (low) temperatures, those curves will result in the same fan speed. So I'm not sure that's an issue.

 

Second, you don't appear to have the thermistors for the Commander Pro installed. Ideally, you would have these at various points in your case and base your case fan speeds off of the case temperature rather than the CPU temperature. This is especially true in a liquid cooled system where the CPU isn't heating up the case.

When I originally installed my Commander Pro, I didn’t have those thermistors installed and worked perfectly fine with Link 4. I think whatever the CPU is at the given time, I should still be able to change the fan curve between Quiet, Balanced, or Extreme, but in this case I can’t and that’s what I’m trying to figure out.

Regardless of what you intend to use as the control variable, get off the Quiet/Balanced/Extreme presets. If you are using a mystery curve with no visible control points, it shouldn't be a surprise you get mysterious results. Either way, the fixed % and fixed rpm controls are tucked away in the custom curve settings. That would be a better test as to whether the fans respond or not. Hit the + on the left side to create a new "cooling mode" (this can be renamed). Create your own appropriate control points or shift the fan around to a few fixed speeds to demonstrate if you have control or not.

 

Also, in relation to changing fan speeds, don't forget iCUE works the opposite way of Link (and most other programs). You don't click the fan, then apply the setting. You click the setting on the left, then click all the fans/pump on the right you want to have that curve. They will highlight yellow when applied. Dark when not.

And ... if we were still in the days of Link, I would tell you the exact same thing.

 

You don't need the thermistors. And you can set your fan curves without them. But you really should use them; it's a better (and more appropriate) method to manage your case fans, especially when you have liquid cooling.

Alright, I’ll go ahead and use them. Where would the ideal location to put these thermistors?

Hard to say, exactly. You'll want to find the hot spots in the case - think about where and what you actually need to cool.

 

For an example, in one of my cases, I have one above the pump header, near the bottom of the case, and in the radiator intake and exhaust. In another system, I have temp sensors just inside each the drive cages (each can hold 4 drives) and one in the middle of the case.
