Noctua NF-A14 IndustrialPPC

Hi vsg28,

I have the fan controller already. I don't know if it provides enough power to get 3000 RPM since the fan requires 12v and it says not to use the motherboard header.

I was going to convert the 4 pin to a 3 pin to use it with the Lian Li fan controller. My case has only one fan spot available and I would like to maximise what I can get from it. I wouldn't be using the 4th wire since its manual control and not software.

It's not as simple as cutting off the 4th wire. But if you do know what you are doing then go ahead. I would like to think a fan controller can provide enough power for a single fan but if all you want to do is max it out, why not just connect it straight to the PSU? Make a full size molex or SATA connector itself and call it a day. It will be loud though!

See if the box on the controller provides more info on max watts provided or something. If not, best to hit up Lian Li.

The NF-A14 IPPC 3000 is rated 6,6 watt. What is the load rating of the controller?

Hi doyll,

The box doesn't say watts but it says 12v 2.8A.
I checked a few online calculators but I'm still non the wiser.
The calculators say volts x amps = watts. 12v x 2.8A = 33.59 watts.
There are 4 available fan control points. Is it right in saying each point will output a max of 8.39 watts (33.59/4)?

Thanks,

FYI this fan would not even startup with 7v (hard wired molex) when I tested it even with other load on the affected rails - eventhough it is rated ~6v starting voltage. I queried Noctua directly and they say it depends on whether a method applies resistance or simply lowers the voltage to modify fan speed. They even added an FAQ after I asked:

I would guess that the fan may not even startup.

That would be my guess.

I usually use the CPU and/or GPU PWM signal to control PWM case fans and use PSU 12v power. This allows fans to run at same percent PWM as cooler fans. Not sure what RPM that would be on a 3000rpm fan. I usually use Thermalright fans. Low priced and definitely as good as Noctua.


NF-A14 IPPC fans are good, but I think TY-14x series are just as good (at rated rpm) and much cheaper.

I have been told Thermalright was first to use this blade design. Problem is the TY-14x series of fans have 104.5mm mounting hole spacing (120mm fan), not 124.5mm spacing of 140mm fans .. but a simple plate adapter solves that .. problem is I have no idea where to find one .. but do know how to make them. :D

But they use 120mm fan mount spacing and are not square. I have made them 140x140mm with no problem.
 
Surprisingly I have a Thermalright low profile CPU cooler from last year that would match nicely with a TY--140. The cooler doesn't really leave much room for fluid airflow through my mini-itx case. The PSU is practically on top of it. I might try it again later today since I got a PSU bracket for a bit more space.

I was hoping the NF-A14 iPPC-3000RPM PWM would work because its rated 158.5 CFM.

Thank you,

I assume you have either an AXP-100 or AXP-200. I found the 100 works very well with stock fan reversed to draw air from motherboard .. and in your situation with PSU directly above the PSU would take the cooler exhaust out of case. Assume AXP-200 would work same way.

My rational is if fan is pushing into cooler cooler exhaust hits mobo and turns out, hits GPU, RAM, etc., and turns up, and as it passes fan is drawn back in and through cooler. But with fan pulling out of cooler the air flows over mobo to CPU, up through cooler and fans into PSU or out vent. Doing this netted me 5-9c lower temps in case .. 5-7c on open bench test station.
