Asus PRIME Z270-A and case fans

[HappyWalruz]

Im doing a first build ever and I need some help.

I have a Asus PRIME Z270-A motherboard and a NZXT s340 pc case which has 2 case fans included in it ( 1 back exhaust and 1 top exhaust ).

What Im planing to do is to get 2 more case fans and put them in front as intake.

My problem start there as I dont know what is the best way to connect those 4 case fans to my motherboard which only has 2 chassis fan connectors. My motherboard also has "AIO pump header" and "high AMP fan header" , could I possibly connect case fans to those headers, would that work?

Maybe some experianced PC builders could help me with that.

In case u need my pc specs this is my PC:
Intel Core i7-7700K 4.2GHz Quad-Core Processor
Cooler Master Hyper 212 EVO
Asus PRIME Z270-A ATX LGA1151 Motherboard
G.Skill Trident Z 16GB (2 x 8GB) DDR4-3000 Memory
Kingston SSDNow UV400 120GB 2.5" Solid State Drive
Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
MSI Radeon RX 580 8GB GAMING X Video Card
NZXT S340 (Black/Red) ATX Mid Tower Case
SeaSonic S12II 620W 80+ Bronze Certified ATX Power Supply

Thank you in advance.

The NZXT S340 chassis would be more of ideal case for those looking at AIO cooling. The front area being devoid of fans is testament of users opting to slap on their own choice of fans and AIO's would naturally come with a pair of their own fans. Regardless I know for a fact that the case fans bundled with the S340 are 3 pin fans which means that you're going to need voltage regulation headers on your motherboard. The only possible locations are located far from the mounting locations on the case which would naturally ask you to buy/make extension cables or you could go with a 3 pin fan splitter and have all your fans connected to it and in turn it's connected to the High amperage fan header on your motherboard but that could bring about some cabling mess.

The sort of splitter I'm talking about is this.

Or you could just pick up 4 PWM fans and a PWM fan splitter(courtesy of Akasa) and have the the splitter connected off the CPU_OPT fan header on your motherboard.

High AMP fan headers are designed for fans that need more then the standard 1 amp of current, but will run normal fans just fine. Depending on the fans you could run 2 normal fans from the high amp header as it can supply a higher then normal current.
AIO pump header is similar in that if will also run normal fans, but you may need to look in your bios at the fan settings. Sometime AIO pump headers are set to 100% on (fan curve) as to run a water pump constantly at max power. So you may need to tinker with the settings.
