Can someone help explain the fan controllers on the phantex enthoo cases and nzxt cases (H440)

[CorgiBro]

Can someone help explain everything about the fan headers? Ive read things that clash with eachother about the controllers, like "Oh dont plug it into the alternate cpu header, or it will only take these numbers of fans before it "Blows up". I need halp

How can they conflict? They're completely separate from each other, the fan headers on the motherboard and a fan controller that is.

I have most of the fan headers occupied on the Noctis 450 (Essentially the same as the H440)

 

You can control them via PWM I think, and it hasn't blown up yet... Its powered via SATA I think

The H440 ones plug directly to a PCB break out board from 12 V power via the PSU so there is no control in terms of fan curves of settings;

On the Phantek's cases it uses a PWM controlled input and require 12V to power the Hub it then converts that to be a recolonized signal to control 3 pin fan it's a strange setup.

Note if you are directly using splitters off a a header on the motherboard and not giving it external power you can only connect 3-4 fans which is a good rule of thumb to not overload the motherboard fan header's capacity (1Amp usually).

So I should always have the SATA connected along with PWM just incase? Also, since it has PWM, i can control the voltage for each fan no matter the amount aslong as i have SATA power?

Having powered via sata is recommended and no it's a group controller like all fan hubs you can't individually control fans.

 

Also note the for PWM fan hub it's not actually a PWM fan hub, from what I can gather without taking one apart myself it take the PWM signal from the motherboard and converts it to DC voltage control since the headers that allow you to connect fans are only allows for 3 pin fans where the missing 4th pin is the PWM control line which is non existent which baffles me.

I meant if I have the SATA power with the PWM cable, can I control the speed. NOT INDIVIDUALLY, i wasnt clear on that, just their speeds in general if i have the whole hub filled.

you can fill the whole hub it operates 2 ways, 1st off the 1st fans pmw (cpu_1) all the fans go off whatever that fan is doing, helps to have similar fans. 2nd way is molex, those run at full speed the whole time and do no change rpm. Does this help?

In theory yes for a normal PWM hub, but it's not a simple PWM header since it lacks the PWM pin so I would test it.

i noticed that too, it does vary the rpm, it has to do it with voltage though, i should get my multimeter out..

Plz let me know if you do check it I've been so confused about it and not being able to give a direct answer.

I believe it would use PWM to control the voltage for the fans connected, controlling their speed. The power is coming from the SATA and is controlled by PWM it seems.

PWM and DC voltage control are different the input is a PWM signal from the motherboard but the connections off of the hub is only 3 pins and lacks the PWM line that control the PWM capacibilies.

so, my case is in a bad spot and i haven't gotten the meter out yet but, the cable that goes from hub to motherboard is 4 pin, so it can have a signal from the first fan which should also be PWM, then i guess it just feeds 12v and varies the amps as software only read that first fan anyways.
