3pin fan hubs?

[JokerProduction]

So I've got an itch to upgrade my old PC case but with that I will be losing my built in 3pin 50,80,100% fan controller.

 

First some pertinent info on my setup.  The motherboard has 2 3pin controllable headers 1 of the headers is used for my 2 rad fans leaving one open that I would like to use for the remaining 5+ fans.  I read the entire manual and no where does it say the max power or amp draw the header can support so that leaves me a bit leary of just using standard splitters (Y) cables.(and the fact that one of the cases I'm looking at will be using 8 or 9 fans off the single header)  The motherboard is a msi z97 krait if anyone might somehow know or have experience.

 

Is there a product out there that would take power from a sata connector but signal(analog voltage) from the Mobo (like a repeater/amplifier for long LED strips)

 

Is there a product out there just like above but with a PWM input but Voltage control output(and can handle 5-9 fans)?

You can plug in 3 pin fans into 4 pin fan headers

What case are you looking at? Most hubs/splitters that support that many fans will usually be powered off of the psu.

The motherboard fan headers should safely power 2-3 fans each.

PWM input and DC output doesn't make much sense for most cases. What fans are you trying to control? There are hubs that take in a 4pin PWM signal and supply a similar PWM signal for 3pin fans.

I'm aware of that but they then run at full speed with no control I'm hoping to have them ramp down to 50% on idle then up to 80% when in use.  My motherboard has 4 separate fan headers, 2 are for 4pin (pwm control) and the other 2 are for 3pin (analog voltage).  One Has to be used for my 2 cpu rad fans leaving me with just the one controllable header left for 5+ fans.  Hence I'm looking for a solution.

I'm really torn between the coursair 460x which will have 3x front 120, 2xtop 140, and 2 more 120s sandwiching my rad on the back spot and the Thermaltake view 31 which needs 6 fans for the front, the rest would be the same.  I already have all the fans, so I would like to use them. I just need to find a way to control the shear amount of them as I really don't want to run them 100% all the time( and I probably cant find all the low noise adapters anymore in order to just use a sata adapter and a few splitter cables)

 

I heard its pretty tight on the back side of the 460x so I need a compact hub more than likely.

 

The fans are the older TT Riings that are 3pin I have a ton of them.

 

You have a link to some of the hubs your talking about?

Phanteks has one: http://www.phanteks.com/PH-PWHUB.html

This looks like It will work perfect for me.

 

 Do you have any experience with that product? Some of the newegg reviews are dubious but considering these come factory in a lot of the phateks cases there should be a fair amount of them working properly out there. 

 

Either way for ~20$ its worth a shot.  I'll just have to set up the fan curve on one of the 4pin headers.    I quickly read the manual and it suggest using similar fans if you want the speed reading to be correct which I do.  There is a good likely hood that I will be connecting up both the 12cm and 14cm fans which are slightly different speeds 1500/1400. 

 

Although now that this device is on a 4pin header I suppose another solution would be to use the hubr on a 4pin header, use one 3pin header for my 2 rad fans and the now leftover remaining 3pin header for the 2 14cm fans and just run the same fan curve on both the 3pin and 4pin headers.  going this way ill get proper speed readouts from all 3 sets of fans.

I've used the one that comes with Phanteks Evolv cases. It works fine. 

The rpm is read only from the first fan. The max rpm doesn't matter since the hub sends a percentage duty cycle signal.
