Currently using a NZXT Kraken X41 which has a FX V2 Radiator Fan on it on a push exhaust setup on the rear of my case. Using two Fractal GP14s on the front normally running at 100%
It's started to make occasional clicking sounds which I'm assuming is the bearing going.
So looking at changing it to either a Noctua NF-A14 (and buy the white corners) or a ML140 PRO.
Anyone had experience with either of these fans? Other forums seem to just say "choose whichever one you like"
Corsair is about £5 cheaper if that affects anything

noctua nf a14. quieter and shoots out more cfm at less rpm than the corsair fan

NF-A14 PWM or FLX shouldn't be 5£ more expensive than the ML140 PRO though.
NF-A14 industrialPPC-2000 (PWM or not, but PWM is the only one that would cost 5£ more) or ML140 PRO are both the wrong choice.
If you're bothered by clicking on a 1000 rpm fan you're probably not going to appreciate the noise a 2000 rpm makes when operating normally.

A FX V2 ramps up to 2000RPM when maxed, and the clicking is down to a dying bearing, so I'd rather replace it before it dies completely or the sound gets worse.
the NZXT fan peaks at 37dBA whereas the Noctua is somewhere around 25dBA. As a rough rule of thumb the volume doubles every 3dB, that seems quite a decrease in noise level to me.

Sorry, I skipped straight to the GP14.
I don't have anything for the V2 but it shouldn't be too different.

So the difference would be more like 3dB total.
Also we're talking about rads so there will be significant resistance and in those cases you should probably have a look at these.

Because on paper the ML140 PRO looks decent, slightly lower static pressure and CFM than the NF-A14 or the FX-140KRX but in reality it sucks dick.

Probably should have pointed it it was the rad fan, case fans are pretty quiet so I don't think they need replacing unless there's an alternative that would make a noticeable difference in cfm/noise level.
As I said before isn't 3dB roughly double the volume?

I would assume I'd need more static pressure to work effectively with a radiator no? Therefore the NF-A14 industrialPPC-2000 PWM would be the best option?

No, with 2000 and 1000 rpm fans the noise from the 2k fans will dominate anyway. As long as they can push enough air through a dust filter it's fine.
3dB is not double the volume.
3dB would be twice the power, since power is a power quantity (duh) or sqrt(2) the sound pressure, since pressure is a root power quantity (you can guess where that name comes from).
10dB or 10 times the power or a bit over 3 times the sound pressure is percieved as being twice as loud.

Yes, against the FX v2 it might be slightly in favour of the NF-A14 iPPC-2000 or not, but the FX isn't an option because that's the broken one you're trying to replace and against the ML140 PRO it's no contest because that thing sucks. I mean if you look at free flow CFM it's 106 for the NZXT, 103 for the Noctua and 90 for the Corsair, but the NZXT is the loudest and the Corsair is the quietest. Similar for static pressure at no flow. NZXT and Corsair almost equal, Noctua a bit ahead.
But now look at what happens at 1mmH2O. NZXT and Noctua get something between 85 and 90 CFM, but the Corsair drops below 60. And it only gets worse the higher you go.

May be worth contacting NZXT then regarding a fan replacement, may be cheaper (possibly free) than forking out for a Noctua industrial if the noise level and cfm is marginal.

Yes, if they send you one (might be Aer P instead, don't think they've got any FX V2 left) that's always going to be cheaper.
If you're not running the FX V2 at full speed you could get away with an NF-P14s redux-1500

Looking at that bitfenix spectre pro i may forgo even contacting nzxt and pick up one of those for £12.
Would expect that to be cheaper than the shipping from NZXT in the US.
