SP120/140 Running At Half Speed On Extreme Profile?

[FreakyFreak87]

Okay I have a Corsair 1000D case and in it I have a total of 16 fans,  8 in the front for airflow 6 on the radiator for push and pull and 2 at the back for exhaust .

 

The 6 140 on the radiator run just fine at around 1500/1600 rpm, but the 10 remaining 120, 8 on the front 2 in the back, all hooked up to a commander core from the case and the elite capellix commander core, on the extreme setting never exceed 800rpm it seems, even on the extreme profile when the fans are rated for 1500rpm, is there a messed up setting or certain temp it has to reach before it uses it's full potential?  I'm confused as to why the entire array of 10 of them set to extreme refuse to exceed 800rpm. These are what I have.

You have two different controllers (Commander Pro and Core) and those presets have a different meaning on each. The Commander Core is specifically designed to be the external controller for the AIO. Its presets are designed to that effect with low/high fan speeds to match a typical coolant range (23-40C). The Commander Pro is an older controller and it defaulted to using cpu temp but on that same 23-40C range. That causes it to run at near maximum even at idle, regardless of which preset you choose. 
 

To that end, most users should ‘make a copy’ of the preset they intend to use so they can see and edit the data points. In the cooling tab click yellow + to create a new custom curve. A graph will appear and below it all the the three water cooling presets. For the Commander Core you should set this to H150i Elite Capellix temp as the proper control variable. The radiator fans only need to run as coolant temp increases. You can easily tweak minimum or maximum values now. For the Commander Pro the sensor choice can be coolant temp as well, but be aware it needs CUE running to fetch that data from the other controller. It’s native control source are the temp probes and those can be used near the exhaust as a measure of case ambient temp or on the back side of the radiator as an equivalent to coolant temp that works at all times.

2hoops that's where I messed up, I have the radiator fans running to the commander pro.... In the case instead of the commander cores.... Anyway to fix that without rewiring everything.

Correction, I have the radiator fans running to what I assume is the commander pro that comes in the Corsair 1000D, I have 6 running on the commander core I think that came with the radiator and 4 running on the commander core XT.

It won’t matter if you are running CUE. One controller can fetch data from the other. However, it is part of the safety feature set. The coolant temp is read by the Commander Core at all times. If you boot into the bios and suddenly hear the fans on crank up, that is a warning sign something is wrong. This is a critical issue if you run a non-Windows OS or spend a lot of time without CUE for whatever reason. If that’s not the case, you can get away with it but I still recommend correcting it if you can. 
 

Do you have a Commander XT in there too?  The names are annoyingly similar. The 1000D comes with a Commander Pro necessary for the case sails lighting, but also a 6 fan PWM/DC fan controller. The Elite Capellix comes with a Commander Core necessary to deliver power to the pump (extra wide cable on the side). The Commander XT is a standalone Commander Core intended for general use with no special power socket on the side.

I've ran it in this configuration since July of last year, icue always runs regardless, no major issues or fab ramps.  So it's ran perfectly fine and I didn't even notice that it was an issue.  Readjusted the fan curves so 10 of them ran on the CPU package temp and the 6 at the radiator run at the coolant temp.

 

I have 4 total, 4 hooked to a commander core XT, 6 hooked to the PC commander pro with a lighting node and then the commander core that came with the radiator that controls 6 in front.

As long as are aware it can’t fetch the data without the software, then that’s all that really matters unless you spend a lot of time outside windows. 
 

All three Commanders will do something different in their default config. 
 

Commander Core - follows coolant temp 

Commander Pro - follows cpu temp with incorrect scale keeping fans high at all times

Commander XT - follows cpu temp when cue running but with correct scale and some hysteresis. 
 

Neither the C-Pro or XT defaults are helpful, so you want your own curve regardless of setup.  Once you give it new instructions, they will follow when CUE is running. Com Core can read coolant temp without software. C-Pro and Com XT can read their own temp probes without software. All three controllers have the same sensor options when CUE is running.
