Hey what Noctua Fan should I get from these 120mm ones


Noctua NF-P12 120mm Ultra Silent Fan, Vortex-Control - 1300/1100/900 rpm
Noctua NF-S12B FLX 120mm 1200/900/600 rpm SSO-Bearing
Noctua NF-S12B ULN 120mm 700/500 rpm SSO-Bearing


I need it for my TRUE-120, or I could swap it for a front antec case fan and put the new more silient Noctua fan in the front pannel harddrive bay.


Being Quiet is a high priority.
I thought I would eliminate the NF-S12B ULN because the NF-S12B FLX can get to 100rpm above the lowest setting of the NF-S12B ULN(no reall difference), meaning the NF-S12B FLX has more advantage over it/more range of speeds.


Now I cant choose between the NF-P12 120mm and the NF-S12B FLX. The NF-S12B FLX has more range of speeds to 100 rpm below the NF-P12, a middle 900rpm and an option to make it completely silient at 600rpm.


I also found some reviews which showed the NF-S12B FLX having 1200rpm producing more air/CFM at a lower dBA then the NF-P12 at 1300rpm, and NF-S12B FLX again has more CFM and lower dBA over the NF-P12 when both are at 900rpm.
Can someone say why would you want to get the NF-P12 over the NF-S12B FLX and what are the advantages over it.


Thanks for your help.

I thought the P12 would be better or is designed more specifically for being a heatstink fan
but these are five review test that Ive seen were the S12 FLX gives lower temps on a True-120 compared to a P12.

All using the TRUE-120, besides the last 5th review
The P12 only wins with 2 of them(one one review) on a true-120 which I reckon is a waste of money.

True-120 must have wide fin-spacing?
"As shown by the results, the NF-S12B FLX is a wonderful piece of engineering and technological advancement! However one thing that has become apparent in the use of the fan, is that there is now less need for the P12. With the S12B FLX performing better in low impedance situations of which most of the market will be using. The P12 is then pushed further into the corner as an 'extreme product' for use by those that use radiators with tight fin spacings, which in terms of market share is a very small percentage."


The only con I see is the "Lower Static Pressure than NF-P12" but the results show lower cpu temps.

Doesnt it depend if the TRUE-120 has wide fin-spacing or tight fin-spacing? Looking at those reviews it shows it has wide fin-spacing?

Pretty niche question, you'd get more replies on the Overclockers NZ, Gameplanet or Computer Lounge forums.
