Hi, I’m having trouble running 9x fans off my motherboard (Asus Maximus X Hero z370) I tried these 3x Deepcool fan hubs (Not powered) they have 3x inputs on them but when I plug them into my board 3x fans per header they work but I can’t control them in bios? Like I can’t monitor fan speed they come up as NA in bios??? I tried enabling them but it won’t let me it just says NA… I found this:
Its a powered fan hub with 10 ports, will I be able to monitor all my fans in bios and adjust fan curves? I don’t like software control Ai suite is terrible, I just have a Be Quiet Dark Rock Pro installed with one fan. Reason why I need so many is I bought a Lian Li Dynamic XL case with 9x Deepcool ARGB fans but 1x died so I’m returning them I realised RGB is not for me I just want to be able to configure 9x fans so they don’t run loud in my system.
I only have 2x channel fan headers on the board the other header I plugged into a Pump header which makes the fans run very loud, will that Deepcool hub allow me to run 9x fans and configure them? Thanks in advance I’m stuck on this…
I have not bothered to research it, but fans aren’t like USB devices running off a bus, addressable and individually controllable.
As far as I bothered looking , fans are pretty basic things. Other people know the exact details, but you basically have 3 wires, a supply, a drain and a monitor. The mobo/header supplies x amount of volts, which the fan uses, and the monitor returns the effect, as a voltage or whatever.
Multiple fans off one header is too complicated for a board- it must either average or total the monitor signals, neither of which would always work, so it just doesn’t bother afaik
I don’t imagine there is a little computer measuring the actual rpms and cfms in normal consumer fans.
Not sure about the four pin ones, but I’m sure it’s just basic, but maybe they do measure rpm?
Personally I just buy quiet fans and run them full off the power supply (maybe with an in-line reducer/resister), and not even think about them, until several eventually burn out and needed replacing.
I am now going to be googling (ddg.gg) this though, so thanks for asking
I would rather just use a sepperate fan controller for this.
Simply because there are no z390 boards that offer that amount of fan headers.
So you can pretty much control the amount of fans based on the amount of fan headers,
your particular board has.
At least when it comes to individual control from software or uefi.
You could use a fan spliter and put two case fans per header,
but i would generally not recommend that cause you cannot control them individually then,
and next to that you might burn out the said fan header.
So if you trully need 9 case fans to be individually controlled. ( for only god knows why…?)
Then i guess the only real solution would be a dedicated fan controller.
No. You will be able to monitor one fan and the adjustments you made for that one fan will affect all 10 fans on the hub…
I am not entirely sure when did the case manufacturers parted with the some fan controller switch. Maybe the switch said something about the case manufacturers girlfriend, cause they moved towards its slightly retarded brother - RGB…
Honestly I use a simple 3 speed switch that comes with my case. I can recommend fan splitters so you can run 3 or 4 fans from one fan header, but you still need PWM 4 pin fans and you still are able to control all 3 or 4 fans as a group, not each one individually. For individual control you may want something like the NZXT digital Fan controller garbage thing… You can’t have those fan controllers that used to be mounted in optical drive bays cause you don’t have optical drive bays… So you are kinda limited…
Funny how progress means more limitations, huh? Top of the range case, no fan control on it, no optical bay, no nothing…
Fan headers can often deliver 1.5A, wich is technically sufficent for 9 fans, allthough that is pushing it (6 is fine though).
Thing is, with fan splitters, you will not get RPM reporting. (Like @MisteryAngel said).
DeepCool’s website states:
Each port has its own PWM function and the fan speed can be adjusted at the same time (only the speed of Fan 1 can be identified by the system.)
The only fan controller where you can manage 9 fans individually is the AquaComputer Aquaero 5.
There is a cheap option: Analog front panel fan controler. Turn the knob up until desired RPM (or noise level) is reached, done.
From an electrical standpoint, yes. Aerodynamically, not so much.
4pin fans are GND, 12V, Sense, PWM
GND and 12V supply the power.
Sense is done by sending a signal each revolution.
Can I ask what you need 9 fans for? I’d imagine they can likely be controlled in groups, in which case you’d be able to use splitters and control with dc instead of pwm, or use controllers for each group. For example, lets say you have a 360mm rad and a 240mm rad, each in push pull. you could put the 6 fans on the 360 in one group, and the 4 on the 240 in another. That would be my go to solution, or look into getting a proper fan controller, as others have suggested.
Thank you so much for the response guys, I did buy them but 2x of the fans died in one day so I returned them and replaced all with 10x Corsair ML non RGB fans. The amount of cables was just insane! I fixed the fan control issue by installing 2x Deepcool powered fan hubs each hub can take 10x fans but I used two to even distribute the load just in case lol. Thanks again.
