Fan Suggestions for my Corsair Carbide 300R

[xmotionx]

The fans I have currently are:
Front: 2x Bitfenix 140MM
Rear: 1x Corsair SP120
Top : 2x Bitfenix (Spectre Pro?) 140MM
Side: 2x Corsair AF140

I'm looking to swap out the fronts. Corsair and Noctua seem to be popular, but as far as the different types of models goes, I'm super lost.

Noctua NF-A14 are good
P-14S redux are good as well

As are Phanteks PH F140XP or F140TS

Cougar CFD-HB are quite nice as well.

Or BeQuiet Silent Wings

Hey. Thanks for your reply. But I still don't know WHY any of these are good. Is there anything wrong with Corsair SP140 with what you've suggested?

just the performance.
Corsair SP140 - Air flow: 84.1m³/​h • air pressure: 1.17mmH₂O • Volume: 29.3dB(A)
Noctua AF-14 FLX - Air flow: 115.5m³/​h • air pressure: 1.51mmH₂O • Volume: 19.2dB(A)
Phanteks F140TS - Air flow: 130.9m³/​h • air pressure: 1.21mmH₂O • Volume: 19dB(A)
Phanteks F140SP - Air flow: 139m³/​h • air pressure: 1.33mmH₂O • Volume: 19dB(A)
Noctua NF-P14 FLX - Air flow: 110.3m³/​h • air pressure: 1.29mmH₂O • Volume: 19.6dB(A)
Cougar CFD D14HB - Air flow: 124.40m³/​h • air pressure: 1.4mmH₂O • Volume: 18.0dB(A) (actually slightly louder)
BeQuiet Silent Wings 3 - Air flow: 101.09m³/​h • air pressure: 1.08mmH₂O • Volume: 15.5dB(A)
BeQuiet Silent Wings 2 - Air flow: 102.6m³/​h • air pressure: 0.81mmH₂O • Volume: 15.8dB(A)

imo there's no justification to buy Corsair SP140 anymore.
they move less air than most decent 120mm fans, are louder than most 120mm fans and got mediocre pressure.
for a 140mm fan that's just straight poor.
