Where to plug in H440 fan hub?

[That_Person]

I am building my first PC in a Nzxt H440 and I have put all the components in, but the front and rear fans won't turn on. I noticed that the fan hub is not connected to some source of power. Where do I plug the fan hub into to give it power. The problem is that I don't have enough CPU fan headers on my MOBO for my 4 fans

That gadget is the optional fan hub, which will power your case fans.

"It uses a standard molex connector to power up to ten fans or 30W." Unfortunately, the hub does not give fan control and will have all fans running at 100% RPMs.

NZXT SUPPORT states.

You can lower the fan speed natively by using a voltage adapter between the molex and the hub.

You may connect the hub to your motherboard, but we strongly advise against this and will not cover any damage resultant of connecting the hub to your motherboard headers. Motherboard headers cannot support more than 1.5 watts per header in most cases, much less than what would be required by the hub.

I have the NZXT H630 , powers up the same way , with a molex from the power supply.

PLUG HUB MOLEX INTO PSU MOLEX , then connect fans to HUB.

I believe the fan hub in the H440 is the NZXT Grid, which uses a 4-pin molex adapter for power. Look for a cable or port with four big pin holes inside it coming from the fan controller.

You'll plug in a molex power cable from your PSU directly into the molex port on the fan hub.

A 1250 rpm 140mm fan will draw about 0.15 amps. So if you have 4 of these, that would be 0.60 amps.. You do not need power input to the hub as long as you do not exceed the power rating of the MoBo fan header ( usually 1 amp).

Proceed as follows:

1. Do not connect the power cable. You should have a female by female 3 pin cable which you would run from the 3 pin (single) IN port located under the "T" in the stamped NZXT on the Hub's plastic casing to a DC voltage 3 pin chassis fan header on your MoBo. newer MoBos may have 4 pim headers but that doesn't make them PWM. On Z87, 4 pin chassis headers are almost always DC voltage and work well w/ 3 pin fans. On 797 the 4 pin chassis fans are usually dual function, either auto sensing or you can set in BIOS how they operate whether DC or PWM. .... you want DC voltage control.

2. Connect the 4 fans in the case to the 3 pin OUT ports on the hub

3. Set up fan control with your MoBo utility.

Again, look at that link

Includes

• 1x Fan Hub

• 1x 200mm Molex to 3­pin power adapter

• 1x 200mm 3­pin female to female adapter

• 2x 200mm cable extensions

• 5x Black zip­ties

The one in BOLD is the one you connect from the single side port to the MoBo.... the fans go into the hub's other ports.

According to the THG review, the fans are"

one 140mm 1200 rpm
three 120mm1000 rpm FN V2

NZXT site says they are 0.16A for the 120s and 0.18 for the 140 so your 4 fans will pull only 0.66 amps total only 2/3 of the MoBo header rating so you are absolutely fine....no worries here.

I have 16 fans in my case connected in this exact same manner using 3 hubs (6 rad + 4 rad + 6 case) running two years w/o issue. I have has as many as 8 fans on one hub.

You can connect the power cable but only if you want the fans screaming at 100% speed 24/7

can i connect 4 pin fan here? http://prntscr.com/arwynv

MoBo Header => Hub Input
Hub Outputs => Fans

Again:

1. If the total number of fans adds up to less than 1 amp load, if you do NOT connect the power cable, you will have speed control

2. If the total number of fans adds up to more than 1 amp load, if you do NEED to connect the power cable, you will have no speed control

3. The Phanteks Hub however will allow you to control up to 11 DCV 3 pin fans from a PWM MoBo Header with the power cable connected
