Quietest radiator fan: Noctua NF-F12 vs. BeQuiet Silent Wings 2

post #1 of 8

Hello! Quick question here, which fan would be the quietest when used on a radiator in PULL at low RPM? Thanks.

The Be Quiet's would be quieter but the Noctuas would perform better.

Oh nice charts, where are they from? I see the Noctua NF-F12s have low/medium/high tags, what do they mean? Do we know at what power are the bequiet fans running at? That way we could compare it accurately to the different settings of Noctua fans? The diagrams are great nonetheless, thanks.

One odd thing to consider is that different people are sensitive different frequency ranges. If you can listen to each fan and try to judge from there. That way you are sure to get what is quiet to "you"

That may be the best option but unfortunately I can't listen to both. Do you have the rpm/dbs for those graphs? Ty.

The best fans on a rad, in terms of a balance of radiator airflow & noise, are Gentle Typhoons (especially AP-15 & AP-14), and then there's a whole lot of others that come in a distant cumulative 2nd place. Have a look at Martin's (MartinsLiquidLab) test results ...

Martin's Rad airflow to Noise level chart

Full size image link & Full test link.

Looking at that chart, the closer a fan's curve is to the bottom right corner, the better it's Performance / Noise ratio on a rad is. You can clearly see by just how much Gentle Typhoons stand out from the rest of the pack.


I'm not sure if there are any other fan noise / performance testing that was actually done on a rad besides those from Martin. Testing done on air coolers never has translated very well to how the same fans do on rads.

This!

The db rating is just a small part of the equation. The "TONE" the fan generates is more important to me.

I have 16 fans in my 932, CM for case fans and Noc F-12's on the rads. Everyone is controlled with a AQ6 and I never hear them. The only time they spool up is heavy gaming and I'm not hearing them over the game. Benching I'm not hearing them either.

Well, I think it's clear with all the praise going around the Noctua NF-F12s that they must have a nice tone, but since I'm going for a silent build I won't be hearing them anyway. The BeQuiet Silent Wings 2 are said to be quieter than the Noctuas so that's what brings me in. Also because they won't look like crap in my 750D. I am willing to go for performance over aesthetics though, if it's worth the sacrifice hehe.
