Gd question. I forgot, later let u know when I home.Bro, your Fan Hub's 4-pin connect to where? CPU_FAN or others?

K thanks.
Cause according to the manual, if connect to a PWM header, need to connect the sata power. If voltage controlled header, then no need the sata power.
My mobo only have 2 PWM headers.So need to plan.
Oh, i didnt read the manual. I likely connected it to the onboard header.
*ok, i connected the fan hub to the onboard pwm & the power molex, no wonder my 3 internal fans r so lousy. lol. Now much quieter after I removed the molex.

it may mean that you have not configured the 4-pin header that you connect to to PWM-control, it's on voltage-control instead. if that is the case, better to change it to PWM-control, attach the molex power, so that the fans get powered by the molex, instead of all 3 being powered by a single motherboard fan header.Oh, i didnt read the manual. I likely connected it to the onboard header.

no, for "PWM" control, it has to be connected to a fan header that is enabled for PWM-control, and the molex plugged in as well. the fans connected to the hub will be voltage controlled, based on what the "PWM" control signal is coming from the PWM-enable fan header.hmm..so if i connect to on board pwm, i shouldnt connect the power cable, so that the fans can be pwm-controlled?![]()
Finally completed my custom WC loop. Met with some hiccups along the way.
Need more testing to adjust fans and pump speed.

Wow, that's one neat looking setup. Double thumbs up!

Until now I'm still quite confused.
My mobo has only 2 PWM headers; CPU_FAN and CPU_FAN2. According to the Phanteks manual, if I use the Fan Hub on a PWM header, I'll need to connect the SATA power.
But now, I connect the Fan Hub to CPU_FAN2 without connecting the SATA power to the Hub. AND, I'm able to adjust the fan speeds in BIOS.
So probably what wacko said is correct. I have 4x fans connected on the Fan Hub. So Fan No.1 is PWM controlled from BIOS. The Hub then in turn regulate the speed of Fan No.2, 3 and 4 according to the speed of Fan No.1.
But still don't understand why I don't need the SATA power connected.

Nice job! Really like the mobo block area how you looped hahaha
Prolly means that one header is powering all 4 fans. But are they actually running at your designated speed? Got test difference when you plug in/out the sata header?
One header cannot tank too many fans, because if overcurrent can kill the fan header. Rule of thumb (calculate by Power/Voltage), one header should not exceed 0.9 amp (some overhead for current surge)
Sent from Huawei NEXUS 6P using GAGT
it is explained in the manual of the fan hub. basically, when the fan hub is connected to a header that is in voltage-control mode, the voltage it receives from the header is what it sends out to the fans connected to the hub. but if you connect the Sata power cable to it in this mode, the fixed 12V from the Sata power cable "overrides" whatever voltage is coming from the header, hence all the fans connected will run at full 12V speed.

Now I am confused abt the fan hub.
Me too.
YeahThanks.
Yes, think I'd better try with the SATA power connected to the PWM Hub.
But think should be safe? Read that the header best not to exceed 1A. And the PWM Hub not to exceed 30W.
4x Fans think will not exceed that figure given 1 fan is 0.2A and 3W (max).
Tonight go back try connecting the SATA power and see if anything chibaboom.
Thing is, my PWM Hub is connected to my CPU_FAN2, which is a PWM header.

Unless like the Phanteks manual said, my CPU_FAN2 is not a true PWM signal?
