Case fan setup

[tush2912]

Hello Everyone,

I just bought a "NF-F12 3000", later read that its a 24v fan. So want to know whether or not I'll be able to run it at 24v or will have to do it on 12v. Should I return it and get a "COOLER MASTER MASTERFAN PRO 120 AIR BALANCE" instead

My current specs:

Case: Cooler Master Elite 372
Motherboard: Asus Z97-K(only 2 x Chassis Fan connector(s) (2 x 4 -pin))
Processor: i5-4690K
CPU Cooler: Cooler Master Hyper 212X(with stock 1 exhaust fan setup)
Ram: Corsair Vengeance 8GB DDR3
GPU: Asus RX 570 Strix OC 4GB
PSU: Seasonic S12II 620W
HDD: WD 2TB(WD20EZRX)
Samsung 160GB(HD161HJ){from old pc}
SSD: Samsung 850 EVO 120GB
Case fans:
2xTop-Cooler Master Silent 120 SI2(both separately via the MB)
1xBack-Cooler Master Silent 120 SI2(via Molex to 4pin)

Just bought 1x COOLER MASTER MASTERFAN PRO 120 AIR BALANCE
and 1x NOCTUA NF-F12 IPPC-3000
and 2x 4-pin Y-splitter cable, that cost me more than the Noctua.
Also MB only has 2 x Chassis Fan connector(s) (2 x 4 -pin)

So please suggest the case fan setup.

Thanks in advance.

It can run at 12V, just not at 3000rpm. You don't need 3000rpm anyway, it's plenty powerful at 2000rpm which is what my NF-F12 run at. By the way, it's an industrial fan for servers. What do you want to achieve? Positive or negative pressure?

according to this here it runs at 1600RPM max with CFM of 58.6.

Positive pressure, and also is there a way to run it at 24V.

If you want positive pressure, definitely put the NF-F12 as intake. I would suggest putting it on the side so it would actively cooling your CPU/GPU and the VRM if there's no obstruction to the side of the case. So in effect:

Noctua to the intake, upper position if you want better CPU and VRM cooling
1 fan intake at the front
1 fan exhaust the back
1 fan exhaust upward OR instead use this as intake from the bottom to help cooling the GPU

The Noctua F12 I have, operates at 3000RPM at 12V.
Planning to do this:

You really don't need more than 1600RPM anyway, as long as there's decent airflow which there is, you don't need to worry.
Just run it at 12v, and then tweak the speed to quiet in the motherboard settings, 3000RPM is way over the top, the high speed Noctua fans are unnecessary.

The noctua fan I have, operates at 3000RPM on 12V(its a 12V version one). Also I'm running it at 1650RPM fix mode.
Is the fan setup correct or do I need to change the placement of the fans?

You would be running at negative pressure if that's the case, 3 exhaust and only 2 intake. Even if the Noctua is stronger there is still more exhaust than intake. Nothing wrong with negative pressure, just more dust and also more air.

Both of my intake fans are lot faster with high cfm compared to the exhaust ones.
Maybe I'll try and remove the 1 top fan and install it on the side panel, hope it doesn't rattle. Also among the two fan slots on the side panel, only the lower one has space left, upper one is blocked by the cpu cooler and gpu.
