Hi everyone!
First of all, sorry for my english.

I'm interested in aquaero 5 LT. Is it possible to setup several profiles with speeds for different fans?
something like
Profile1
fan1 - 5V
fan2 - 800 rpm
etc...
Profile 2
fan1 - 12Vfan2 - 1200 rpmetc...
And then activate profile with starting some application (like game) or simply select these profiles manually?
I believe the 5LT is similar to the 6 Pro, and It is possible to save & load up to 4 profiles.
But I do not believe you can load profiles dependent on conditions, they are only loadable manually.
BUT, you can set up a controller to manage fan speed depending on system load/temperature.
If you are water cooling you can monitor the water temperature and control fan speed as water temperature changes.
If you are air cooling you can monitor, maybe the CPU or GPU temperature, or both, and control fan speed as their temperatures change.
This way, if you are doing emails with your system and the load is low, the fans spin slowly, and if you are gaming and the load is high, your fans will spin up.
The controller below monitors the difference in temperature between the water and ambient in the room. As the delta increases from 1C to 5C, the fans go from 0% to 100%.
