Mini itx MoBo fan allocation

[Andy_eh]

Hey everyone - first post here. Building my first SFF PC with the following gear:

Motherboard: ASUS ROG Strix X570i mini itx 

CPU: AMD Ryzen 5900x

GPU: 3070 FE

Ram: 2 x 8GB Corsair Vengeance LTX 3600

Storage: Samsung 1TB 980 Pro M.2 NVMe

Power: Corsair 750w Platinum modular

Cooling: AIO NZXT Kraken x63 

Case: Cooler Master NR200 (SFF)

Case Fans: 4 x Arctic P12 PWM’s 12VDC/ 0.08A

 

I have a question about the fans - specifically where to connect them. The board has 3 fan headers: CPU, AIO pump, Chassis. The AIO pump will obvs go to the AIO pump header and the 2 AIO fans to the CPU fan header. That leaves me with 4 chassis fans that need to be allocated and the unused chassis header. 

 

What’s the best allocation for these 4 fans? 3 fans on the chassis header and 4th chassis fan with the AIO fans on the CPU header? All 4 on the chassis header? At 0.08A each that’s only 0.32A on the chassis header. Not sure exactly what the spec is on that header but I’m sure it would be at least 1 amp...right?? Would really prefer not to use a fan hub/ controller due to limited space. 

 

Long post, thanks for hang’n in there and thanks in advance for your solutions.
