Replacing 140mm fans on NH-D15 with new 120mm fans

Hi,

 

Three questions regarding noctua fans:

 

1) I'm wondering how much of performance loss I can expect if I replace the standard 2 140mm fans (NF-A15) fans with noctuas new (much quieter) NF-A12x25 120mm fans, assuming they run the same RPM. Ofcourse I could let them spin faster but that would defeat the purpose of making my system quieter. I'm running an R7 1700 @ 3.9ghz. 

 

2) Would they even fit on there if I attach them with the same metal brackets? Is this possible to do?

 

3) Also wondering why there are no 140mm variants of the new NF-A12x25? 

 

Thanks so much guys

I think new 140 varients are in the works.

Would this work to mount it to the cooler?

I need those tasty 140mm fans now :P

Best & worst cases for your money in 2018 are:

 

Best Cases overall

 

I) Fractal Design Meshify C - Airflow and relatively quiet, best all around case

I) Phanteks Enthoo Pro M / Special Edition (white interior) - Airflow & full water cooling support

I) Fractal Define R6 - Silent with decent airflow

I) Be Quiet! DB 900 (Full Tower) - Airflow and silent 

I) Fractal Design Meshify C mini (mATX)

I) Corsair 400C - Only use with low end components, no 1080 / TI

I) Phanteks 350X - Only use with low end components, no 1080 / TI

I) Fractal Design Focus G

 

Cases that may be worth your money

 

I) Thermaltake G21 - GPU and CPU cooling issues, modest tweaking
I) Silverstone RL06 / Pro - Mustard/Ketchup wires, Shitty cable management, Poor front radiator support, useless psu filter, stupid ssd layout
I) In Win 303

I) Coolermaster H500 no suffix - if 200mm fans are your thing

I) NZXT H700 non "i" version - Needs to come down in price to be worth it

I) Corsair Carbide 100R - Suitable for low end builds

 

The worst cases - Do Not Buy

 

I) NZXT S340/Elite, H500, H440 (everything except the H700) Reason: Poor airflow
I) Coolermaster Masterbox 5

Majority of cases on the market

NF-A15's and NF-A12x25's both use the same standard 120mm mounting holes. 

Changing to NF-A12x25's will generally result in a performance increase but it might not be much quieter. Are NF-A15's not quiet enough?

Ahh ok thanks. Well I was planning on switching out all fans with the new noctua ones, not just the heatsink ones. But thanks for the info, I might just leave the NF-A15's then and save myself some money :-)
