Noctua REDUX vs Be Quiet! Silent Wings 2

[boat]

I have two unoccupied 120mm fan spaces at the bottom of my case begging to be used for intake, and another two 140mm at the top begging to be used for exhaust in my Thermaltake Core V31 case. There is a third 120/140 mm slot at the top for a case fan, but I'll be using it for a Seidon 120V.

 

Once again, I seek guidance from the LTT community, dying on the inside from indecisiveness.

 

I'm going for quiet case fans. These fans are more for satisfaction since I don't spend a lot of time bringing my PC through crazy stunts, so it doesn't get that hot.

 

I already have two Silent Wings 2 for front intake (140mm), and one 120mm Silent Wings 2 for rear exhaust.

 

For the 120mm case fans (case bottom, intake), I'm stuck between these two choices:

One fan will be partially obstructed by my non-modular PSU cables, as it makes its way towards my GTX 970 (non-reference)

The other fan will be blowing directly onto my WD Black 1TB. The WD Black TB already has Silent Wings 2 140MM at the front blowing onto it.

Both fans will be pulling air in through a magnetic dust filter.

 

For the 140mm case fans (case top), I'm stuck between these two choices:

Once I get the fans, I'll probably remove the magnetic filter from the top.

 

Going for 100% Silent Wings 2 would just match the entire collection of case fans (and support my workplace's rival), but I see that there's considerable bit of discount on Amazon with the Noctua REDUX - and that's where I'm stuck on this decision. There's also comparable, yet somewhat different performance numbers in terms of pressure, flow, and noise between these two case fans.

 

Also, liquid cooling radiator at the top > at rear exhaust?

Be quiet would probably be better...IMO

I will choose Be Quiet

SW2's are better than anything from the redux line but NF-s12's are still great but $19 isn't that much of a markdown. They're better competition for SW2's around the $15 mark.

Have the top as exhaust with the seidon and the rest as filtered intake.
