Not enough power to Noctua fan?

[Grizequiel]

I recently got a Noctua fan, the NF-A14 Industrial 3000RPM edition.

I slotted it into my Phanteks fan hub which is connected to my CPU_FAN header and has the stock fan, 3 Jetflo fans and an AMD stock cooler fan connected to it. (Edit: It is also powered by SATA power)
When I turned my PC on, the Noctua fan turned on for maybe 2 seconds and then turned it off.

After some severe testing, it seems as if the fan isn't getting enough power as, when I disconnected one of the Jetflo fans, it turned on and performed perfectly. It also works when I connect it directly to the CPU_FAN header while fails when connected to my only SYS_FAN header.

I have a Corsair CS450M power supply with 35.5 Amps and that should be enough to power all of my current fans through one fan hub since the Noctua fan is only rated at 0.55 Amps.

I'm really not sure why it doesn't want to turn on when connected to the fan hub. I was wondering if the community could help. Would it still be a voltage problem? Or something with my motherboard (which is the Gigabyte F2A78M-DS2 by the way).

Thanks in advance for any assistance.

On your motherboard notice that pins 2 and 4 are swapped around and explains why the fan only works on the CPU_FAN connector but not on the SYS_FAN connector.

The SYS_FAN connector does not adhere to any industry standard fan header pinout that I've ever encountered.

I don't know about your Phanteks PWM fan hub. They claim that it can handle up to 30 Watts.

Three Cooler Master JetFlo 120's plus an NF-A14 industrialPPC-3000 PWM should have a maximum power draw of 21 Watts.

So, if I get a new mobo, would this problem be fixed?
I'm planning on getting a new one in a few months and if this problem is fixed because of it, it would be great news.

So, is there possibly a problem with my fan hub? Or is it still a problem with the required amperage of the fan?

Thanks for the reply, by the way. Wasn't really expecting one.

You will have to check the fan header pinout on the new motherboard. You should be able to download a copy of the motherboard's User's Manual, before purchasing the motherboard, so that you can verify that it is correct.

There could still be a problem with the fan hub. I don't know what method of power distribution they are using inside that hub.

Is there other fans connected to the hub? I don't know if you're including the CPU cooler's own fan(s) in the fan count or not.

I'm still undecided in what motherboard to get but if I get a high end z170 motherboard from a respected manufacturer it should (hopefully) be the correct pinout

If I connect 3 Jetflo fans, my APU stock cooler fan, a rear 140mm fan (came with my case, Phanteks Enthoo Pro M) and the Noctua fan, it doesn't work. Right now, I plugged one of the Jetflo fans to my SYS_FAN header and things are working fine but my PC wouldn't really be open to more fans if this problem persists. I'm also quite curious as to why it doesn't work.

Intel chipset motherboards tend to adhere to Intel's specs so there's a very good chance that all of the motherboard's fan headers will have the correct pinout assignment.

That's two fans more than you mentioned in your original post. There's a high likelihood that you're indeed drawing more power than the fan hub is able to provide for all of the fans.

I'm not sure what you mean by more fans mentioned since, when I look at the post, its exactly the same fans but thanks for the help, really.
You've been great help. I'll get a new mobo with more headers that are correctly pinned and everything should be fine, thanks a lot!

Sorry. I didn't include the CPU cooling fan and the computer case's included Phanteks PH-F140SP in the initial power calculation because you didn't provide a brand and model number for them or the computer case.
