Question Cougar Archon2 Mesh built-in fans question

[CrisR82]

I recently bought a new PC and picked the Cougar Archon 2 Mesh RGB case (no interest in the RGB part but hey) and today when doing some VERY intense workload on it, I finally heard the fans ramp up, which is nice and everything seems to be in-spec from what I can tell but...I am sitting here thinking - currently I have the CPU fan and 3 auxiliary fans connected to directly to the motherboard (as exhausts), while the 3 front fans (intake) are connected to the PSU only.

So my question is specifically for these 3 front fans - if they are operating stand-alone, are they running at full speed? (I understand that obviously nothing is controlling them, so my question is are they working at like constant 50% or 100%?)

The way the manuals for that case reads, the three front intake fans can be powered ONLY from a PSU SATA power output. Further, they have non-standard connections so that all three are "daisy-chained" from the first fan and thus all get the same power AND the same lighting control signals. It is VERY unlikely that you could rig up some custom wiring to change the fan motor power and speed.

By far the most likely way this has been built is that those three fans always run at full speed for max case cooling. Although some other options could have been designed in, that is not likely. As you may have realized, there is NO way to find out what speed they are running. These fan cannot send their speed signals to any mobo connection that reads fan speeds.
