Any advice on slowing down my noisy Noctua NF12 Industrial CPU fan

Spraggzilla

The fan on my CPU heatsink died this week, and the only fan I had to hand as a replacement was the l Noctua NF-12 Industrial 3000 PMW.  As you can imagine, my system is now pretty noisy all of the time.

 

I tried selecting the silent profile under bios (still too noisy), and any attempt to draw my own graph under the "manual" setting only seemed to make matters worse.

 

Does anyone have any advice?  Do I need to buy a new CPU fan?  Should I turn off monitoring of the CPU fan in bios and control the fans using some other software - if so what software and what settings would you suggest?

 

Thanks in advance!

Most Nocuta fans come with a low noise adaptor.  It cuts the speed in half iirc.

Good question!

 

I'm using an Asus Strix Z270E Gaming board

? Use bios and set RPM to ~20-30% i.e. 600-900rpm.

 

Would you be able to give any more instructions on how to do that?

Try Asus AI Suite, it has Fan Xpert+, allows u to tune fan profiles. Its not perfect but it works.

 

if that fails, do try that low noise adapter i mentioned.

Minimum speed on the IPPC 3000 model is a very audible 750 RPM

I wouldn't recommend AI Suite.

 

In BIOS it's under Monitor (for my ASUS board at least).  Find the appropriate fan and in that menu you can key in values for temp and corresponding fan speed in percentage.  You may have to scroll down below where it shows your current fan speeds.  Pro tip: my Noctuas run at 1500RPM at 46%.

Buy a new fan, or get headphones. If you grab headphones, at the very least, you know that your CPU will be cool as can be with your thermal solution.

Did you get a low noise adapter with the cooler? i think they should all come with one, plug it in between the fan and the motherboard and it should cut the RPM

I am struggling a little to alter the fan settings.  The upper and middle percentages seem to be stuck on 60.  

 

Do you have any idea what I might be doing wrong?

Furthermore, what temperatures and percentages do you suggest working with for this fan?

What about the fan is noisy? Is it vibrating? Is the bearing starting to die? is it literally just moving so much air that you can hear it? I've seen all of those situations so I have to ask.

 

I'd get in the BIOS/UEFI and change the setting. I haven't ever been on the board you have (I own a ROG Strix Laptop though) but there should be an option to get in there and change the RPM on the fans.

 

Fan Xpert+ is pretty cool though. I have a few friends that use it. That may be an answer you can use inside Windows. If that would work it might be nice so you can adjust the speed up if you're doing something that's causing the CPU to heat up.

 

 

If the fan is vibrating you need to figure out a way to dampen the vibration (usually I will use rubber washers), if it's the bearing you can clean it up with some WD-40 or something.

In my BIOS there are three temp settings.  If you set the lowest setting to a value of 50% then the higher settings cannot be any lower than 50 as well.  So make sure the lower settings are in fact lower and aren't preventing you from adjusting the middle and highest settings.  

 

And I'm afraid I'm not versed enough in your hardware to recommend any settings in relation to temps.  One thing I can say is that if your board is like mine then your highest controllable temp is 75*C.  After that it will go to 100% fan speed so you may need to find that low noise adapter.  I have an AIO and run my fans at 1500RPM all the time.  I don't sit close to my PC so it doesn't bother me.

Noctua's iPPC fans are naturally more noisy than the non iPPC fans even run at same speed. But if you can control it to run at lower RPM, it can help.

I mean you did buy 3000RPM industrial fans!  They aren't meant to be quiet they're meant to cool.

 

Sell them and buy some Silent Wings 3 fans.  Or embrace Noctua and their beautiful music as they cool your machine like no other.

Thanks for all your help.

 

Yes, I assumed that one had to first alter the lowest setting first.  Sadly whenever I enter a percentage it is automatically adjusted back to 60.  Never mind, I'm sure I'll be able to live with the noise for now.

You're exactly right.  It is, ultimately, my bad for not doing my research.  First builds will never be perfect. 

 

All my other fans are now Silent Wings 3 fans, they are lovely.

I'm running the same fans so hopefully you can get it sorted out.  I'm sure it's a setting you'll find eventually.

iPPC fans don't come with LNAs and LNAs generally don't work with their three phase motors!

 

If you want to slow it down manually, get the NA-FC1.

 

Alternatively, you might also want to try Speedfan.

Do you have option to choose between DC and PWM? 60% sounds like DC setting.

Which header is the fan plugged into? Is the header set to pwm? You may need to re-run Qfan tuning in order for the correct fan rpm range to be detected.

They wont have noise adapters. Use a fan hub, preferably one the cpu header. Then use the proper program being ai suite. Then you can lower them to 550/600 which should be plenty. Or get rid of them and get the 2k version.

At that point, wouldn't it be better just to get regular desktop fan? Which runs rather quietly by default?

Yea, now that noctua offers their regular fans in black. That’s what I would do, especially water cooling now. 

But I’d consider any of those to be regular fans.
