hurricane51 Posted January 16, 2021 Share Posted January 16, 2021 (edited) Is it possible to control my Arctic AIO with the Commander Pro? I have a Commander Pro from a previous build, and I am dissatisfied with the fan controller software that came with my mobo (Gigabyte Aorus SIV).

c-attack Posted January 16, 2021 Share Posted January 16, 2021 The fans? Yes. The pump? Probably not. Most will be either drawing power from the fan controller and you are not supposed to adjust it or they will be SATA/molex powered and either non-adjustable or only through proprietary software.

hurricane51 Posted January 16, 2021 Author Share Posted January 16, 2021 I guess my pump is running at full speed all the time, since the Arctic cooler doesn't come with software and the mobo software only controls the fans. But I like LINK better than the mobo fan controller so I'll probably use that. Link to comment Share on other sites More sharing options...
c-attack Posted January 16, 2021 Share Posted January 16, 2021 (edited) It should work for fan control. My suggestion is to use one of the temp probes from the Commander Pro and run the sensor end to the exhaust side of the radiator. That will mimic the coolant temp reading inside the radiator and provide good, smooth fan control at all times -- software running or not. However, this will be an adjustment for you since you have not been using an AIO that displays coolant temperature. You will so have a few dozen other variables to pick from, but things like CPU temp require the software is running to get the data from the MB.

hurricane51 Posted January 16, 2021 Author Share Posted January 16, 2021 Actually, the spec sheet says the pump is "controlled by PWM". Since there is only one connection to the mobo's CPU fan header, I take that to mean they are both adjusted in concert (simultaneously) based on CPU temp. Is that right?

c-attack Posted January 17, 2021 Share Posted January 17, 2021 I would need to know the actual model we are talking about, but there is no AIO system out there that you want shifting it's pump speed based on CPU temperature. The cooling process does not work that way and the most likely result is poor performance and a short lifespan. Link to comment Share on other sites More sharing options...
hurricane51 Posted January 17, 2021 Author Share Posted January 17, 2021 It's an Arctic Liquid Freezer II. Maybe I can find out more about the pump control. Link to comment Share on other sites More sharing options...
c-attack Posted January 17, 2021 Share Posted January 17, 2021 This is the one with the "vrm fan" built into the pump casing? That is an odd one with it showing a single PWM header that powers pump, radiator fans, and VRM fan. There is probably more detail hidden from the end user, but I suspect the pump is fixed, the radiator fans adjustable through the PWM header, and the VRM fan... no clue. There is likely some type of power management for all that, but frankly I am surprised they got all in the pump housing. I would have expected an external control device. Either way, there should be no issue offloading the fans onto the Commander. All the pics I am seeing are promotional stuff that are always so neat and tidy with no wires showing... and thus totally useless to help with this.

hurricane51 Posted January 17, 2021 Author Share Posted January 17, 2021 The VRM fan runs at a constant speed. There are numerous reviews of this cooler since it pretty much tops the thermal testing ratings. At any rate the cooler is working fine, and since there's only one cable I have no choice in the matter. Whatever happens, happens. Thanks for the help!
