credit of pic you posted goes to Cass who found the pinout.
the AW 5 pin is only 3 pin too: 1/5 is blank, 2/5 are jumped. the liquid pump is never meant to be PWM. it is supposed to run at a constant rpm. again, if I was wrong, Cass may correct me.
Re: the open system vent when fans reach XXX% does not seem to control them. Like the fans will be at like 5-10% but the fins stay at the middle open setting.
that is a question of how to use AWCC. it seems the active vent is not as responsive to fan speed as you wished. I suspect the feature you wished to have is more app dependent than fan %.
Hello I have an Alienware Area 51 R1 (HPXVVH1). My problem is I cant get the fins to move due to problems with the fans being controlled. For some reason in HW monitor the FANIN0 is normal 800-900rpm idle and the system is running at normal fan speeds but the reported fan pwm is running at 100%. I originally thought this would be fixed after replacing the aio it had (the pump died). I did make an adapter for a regular 3 pin to the dell 5pin and it works fine.
If you converted it to a standard 3 PIN FAN, then you deleted PWM control. Fans with 3 wires (including PWM fans converted to 3 wires) have no PWM control. The only way to control a standard 3PIN fan is with voltage regulation in BIOS (or Y splitting it to a 4 PIN PWM fan and having it track the same).

I would not trust HWmonitor app when used in A51. HWmonitor is useful when all fans headers are plugged directly in motherboard fan headers. in A51 R1 the fans are controlled via MIO/daughter board which communicates with motherboard as a USB2.0 device. I do not think HWmonitor is sophisticated enough to know this, thus you get the all 100% readback which is meaningless.
Cass is the recognized expert on this model, so if I am saying something wrong above, Cass may correct me.
regarding fins moving, if you can manually control fins between 0, 50%, and 100% using active vent, then there is nothing wrong electromechanically with them. There are ways to make fins automatically flare up to 100% then back to 50% etc. if you play with active vent settings in AW, but really during normal use you just leave them open at one of the 3 settings. it is impressive when you show your guests that the fins move up and down, but the practical usefulness of them during gaming is considered minimal. It is an AW styling point, not a practical one. If your chassis temp is on the high side, leave the fins open at least 50% perhaps for better air vent.
Well you would be surprised to learn that the 5pin I adapted to is only running 3pin wires. https://imgur.com/a/p6XtJyc
That's what it looks like and this was confirmed by others that use this hardware. Other problem dell removed the fan control from their bios for this system.
Okay that's good to know. What im annoyed by is that the open system vent when fans reach XXX% does not seem to control them. Like the fans will be at like 5-10% but the fins stay at the middle open setting.

As an aside, FANIN0 just means FAN 0. So you're registering 4 fans, plus the CPU fan/pump.
