Noctua industrial ppc nf-f12 3000 PWM running extremely loud.

I'm aircooling my PC right now and am slowly upgrading it to water cooling. So, I picked up some of the fans I'm interested in using. The only issue is the Corsair 780t built in fan controller runs them way too loud on the lowest fan setting. I believe the controller sends 5v on the low setting.

So, is there a splitter or fan controller that is safe to run these on without blowing out a header. I'll probably have about 15 of these in the case when I'm done, with 12 on radiators. I'll probably need to pickup two controllers or splitters. I did notice on Noctua's website they suggest against using most common fan controllers with these.

Anyone know how to safely manage the speed of these fans? They're just unbearably loud right now.

use a PWM controller because otherwise they will stall with voltage control

 

those are extremely loud fans, idk why you bought them if you were going for silence...

use PWM to put them at 20% speed

Does it matter if the fan controller only has 3 pins for each channel. I'm looking at the Lamptron cw611. Have any other suggestions? It sounds like not all of the fan / pump controllers are compatible with all pumps / fans.

PWM control needs 4pins. You should be looking out for controller than has maybe 4-6 channels and splitting each to two or three.

The minimum speed they should run will be around 44%. Should be silent and provide adequate cooling at that speed. I do the same with 2k rpm fans at 40%.

Well, I picked up an Aquero 6 pwm controller. Looks like I need one with the amount of fans, and the pump I'm planning on running. It can run fans from 0 to 100%. Why should I not go lower than 40% on these fans?

The industrial grade Noctua's suffer from the same fate as most high rpm fans in that they can sometimes not spin up at all unless adequate current is being put through them, ~40% to be more precise.

Alright, so I need to hit them with 100% at startup, and from there can drop the speed down?

What? No that's not what I meant. I mean you should find whatever the lowest percentage speed you can have them at and still have them spinning. For a lot of higher rpm fans that minimum is about 40%, but you should find what suits them. All in all, 3000rpm fans, Noctua or not, they're gonna be loud.

I'm sorry mate, but you simply bought the wrong fan. 

 

These aren't designed for personal dekstop computers. They're called "industrial" for a reason. 

 

They're designed to operate at or near max RPMs. That's why they don't respond well to low voltages or low PWM inputs. Notice they don't have a "low-noise adaptor" rating for CFM and pressure on the website, like ALL of Noctua's other fans do?

 

TBH you should have realised, being a 3000rpm fan, that they were going to be extremely loud. 

 

If you desperately require them to be water-resistant and have a near-dustproof motor then you should replace it with the 2000rpm model. The 3000rpm model will be freaking loud no matter what you do to it. 

This is what I think of Pre-Ordering video games: https://www.youtube.com/watch?v=wp98SH3vW2Y
