3900x Cooling (H100i v.2/Noctua Nf-a12x25 Push/Pull)

[NathG79]

I will soon be building my 3900x Rig and have a H100i v.2 which has the stock Sp120 grey finned fans in Push/Pull
Looking to purchase 4 Noctua Nf-a12x25 to replace the existing H100i fans and still go push/pull Exhaust as I want to keep that 3900x nice and cool.

Would these be the ones to go for?.want a balance of cool/quiet but game on headphones so noise is not crucial but don’t want it stupid loud.
I have my existing bottom two sp120’s hooked up to the h100i’s splitter and the top two on a NZXt 6 channel fan controller so that I have manual control when I want full tilt.
(2x 200mm on front of case as intake)
(Vega 64 liquid GPU hooked up to Exhaust at back of case (1x 120mm)
(1x120mm Corsair ML120 on floor of case as intake)

Is there a better configuration. (Rad must go up top as no room anywhere else.(HDD Cages will clash)
(Case is a NZXt H630).

Not interested in replacing the fans elsewhere-just the ones cooling the Rad up top.

Would be grateful for any advice going forward.


My basket at Overclockers UK:

• 1 x Noctua NF-A12x25 PWM Fan - 120mm= £29.99

Total: £32.73 (includes shipping: £2.74)​

Thanks for the input Guys. @Meddling-Monk, your right, budget is not the issue, adequately cooling 3900x is what I want.
If thought I could shave 5c off load temps with the Noctua’s over the Arctic P12s I would get the Noctua’s all day long.

be better off getting a 360/280 AIO rather than putting fans on a 240.

I did look into this, but with the fan controller the 280/360 rad will clash.
I quite like the fact that I can manually adjust fan speed (and noise levels) on the Sentry mix 2 (@Meddling-Monk you are right, it is, so the fan controller must stay).
I want as little overhaul as possible and updating the fans on the AIO seems to be the way to go, and Noctua are the best in class at getting that heat away and although the case (NZXT H630) is a full tower it can be a little restrictive so airflow in the case and static pressure through the rad and out needs to be high on my priority.
The outcome is that I have ordered the 4x Noctua’s NF-A12x25 PWM.
I will post the results in due course but finding time to get this build off the ground is an issue, It’s not something I want to rush.

Thanks again people.

You can control the fans via bios with most Ryzen mother boards.
You should have needed a fan controller. I’m sure 2 of the fans will give an improvement over the standard ones.

Bios Control on the fans has never been something I've liked.
I prefer to have instant control of fan speed if i see temps creeping up.
