Fan stutter

Montag, 7. November 2016, 11:20

Hi,
I've just replaced my 6 Akasa Piranha case fans with Noctua Industrial 3000's and I seem to be getting fan stutter / ticking when I start. I'm using a splitty9 and if I unplug it and then plug it back in on the aquaero it's fine. But restart and it comes back. I've tried start boost and it makes no difference. Also, is it possible to daisy chain Splitty9's? I presume as long as only one is transmitting the final rpm to the aquaero it should be fine but am struggling with this also.
Many thanks.

In which way are these fans connected to the aquaero? Their power consumption is quite high so if you try to run all of them from one port this is likely a possible problem.

Of course you can daisy chain the splitter boards but I would try to avoid doing it.

Hi Shoggy,
They are connected to a splitty9 ands then onto the aquaero port.
Full config is:
pwm1 : 12 x nidec 2150 typhoons via 2 splitty9's at 615rpm at5v and 0.36a @25c in speed controlled mode. 100% = 11.2v, 1.43a @1700 rpm.
pwm2: 4 x noctua 3000 via y cables at 400 rpm at11.9v and 0.00a at 25c in PWM mode controlled mode. 100% = 11.4v, 0.70a @2700 rpm.
pwm3: 6 x noctua 3000 via spliity9 at 300rpm at11.9v and 0.00a at 25c in PWM mode controlled mode.100% = 11.2v, 1.44a @2660 rpm.
pwm4: 6 x noctua 3000 via spliity9 at 300rpm at11.9v and 0.00a at 24c in PWM mode controlled mode. 100% = 11.2v, 1.37a @2670 rpm.
Water temp doesn't go above 25c at these speeds. Using 2x XSPC RX360 rads, 2 Aqua USB D5's.
Am I over doing it?
thanks.

1: 17.72W average, 90.72W max peak :wacko:

2: 14.4W*

3: 21.6W*

4: 21.6W*

*Noctua does not mention in their specs if this is average or peak.

Anyway, that is almost 150W in total or even more if the Noctua fans also have a higher peak. The real problem seems to be the first channel with its insane 90W peak when the fans spin up. I would imagine that you should also see an overload warning in the event log (system tab -> event log -> download event log).

Thanks for the reply Shoggy.
Never had a warning about overload. Where do I see the 90w peek? In Aquasuite the most I ever see on PWM #1 is 11.2v and 1.43 amps. I presume I'm doing the math incorrectly.
I've just run them all at 100% for 10 seconds and didn't receive any errors.
