Switched to Noctua NF-F12's. First impressions

post #1 of 13
Thread Starter 
Been using the stock H80 fans for a long time now. Saw that the NF-F12's came in stock on Newegg the other day so i figured why not. Been running the H80 on the medium setting because i couldn't stand the fans sounding like a hair dryer.

My first impression of these fans couldn't be any better. In my 600T with the H80 in performance mode i cannot hear these fans at all aside from sticking my ear up to the case grill while running prime.

The stock corsair fans do provide nice performance if you can stand the noise but i am seeing a few degrees C improvement running the Noctua NF-F12's on performance mode vs stock Corsair fans at the medium setting.

If the color doesn't bother you and you are looking for great performance while staying very quiet i would highly recommend these.

They are expensive but you get a lot of nice accessories, sleeved cables, and a superior build quality.

Retail box includes:

NF-F12 Pwm fan
Low noise adapter
PWM Y-cable
30cm Extension cable
Anti-Vibration mounts
Mounting Screws.

Specifications

Max Rotational Speed (+/- 10%) 1500 rpm
Max Airflow 93.4
Max Acoustical Noise (db) 22.4
Max Static Pressure 2.61

L.N.A. installed

Max Rotational Speed (+/- 10%) 1200 rpm
Max Airflow 74.3
Max Acoustical Noise (db) 18.6
Max Static Pressure 1.83

Good to see another member having a good experience with them on a H80.
Do you get any vibration issues on them occasionally?, When mine both hit certain RPM's they cause the case to vibrate frown.gif

I have not noticed that yet. I do have anti vibration mounts on my case where the rad screws go through with a washer plus the anti vibration pads on the NF-F12's. Are you also using anti vibration on the exterior side of your case mounts.

On my existing main box I use Noctua's. I like quiet/silent PC's and these are definitely worth it for their performance per dB. I just wish they were available in different colors (or at least straight black). As it is, the beige look just clashes with so many things.

I haven't had any issues with vibration no matter what RPM they are running at but as Silentsoul_600 said, using rubber grommets or anti vibration pads will go a long way to ensuring that it doesn't happen.

Right, i think they might get a larger customer base if they would come out with some other colors. As far as i know though the reason is that if you ever see them in system there is no question as to what they are. You may not know what type of fans are in there if you just see a black fan. I think that may be why corsairs new fans have a unique look as well.

Nice! Welcome to the world of quiet computing. biggrin.gif I felt the same way when I switched to my Gelids.

I'm surprised you could stand the stock fans on 'balanced' for so long. Anything higher than low practically made my ears bleed.

Update:

As Sir Amik Vase stated i did eventually start feeling a vibration from the NF-F12's. Still unsure of how this occurs considering the fans have very good anti vibration and my radiator holes have anti vibration inserts on the case side. To clarify though it's more of a pulse than a major vibration. I assume this occurs from being a PWM fan and the voltage pulsing to keep a relative speed.

I tried to adjust how tight the screws were. Adjusted all the mounting hardware to make sure it was perfectly centered on all the holes. Tried the fans at a fixed rmp and temperature controlled. The pulsing continued.

I am not saying this to turn anyone away from these fans because they are amazingly quiet and perform very well.

I since have purchased a pair of the new Corsair SP 120's "Quiet Editions." I am very pleased with the purchase and in all honesty i believe (to my ears) they are quieter than the NF-F12's. The testing i have done so far put these very very close, within margin of error to the same performance as well.

The Noctua's have since went into my wife's machine in which i cannot feel the pulse anymore because they are mounted directly to her heatsink as apposed to being case mounted on my radiator.

Noctua's relocated to the wife's pc:



P.s. My case sits on my desk and the only reason the pulsing from the NF-F12's bugged me was i could ever so slightly feel it through the desk at certain rpm's. It would not have been an issue at all if the case was not sitting directly on top of my desk.
