Need Help With Fan Setup

[swilds]

First, here is my build:

CPU: I5-6600K
Cooler: Cryorig H7
Motherboard: MSI Z170 Krait Gaming 3X (Already Purchased)
Memory: G. Skill Ripjaws 4 Series 16GB (2 X 8GB) DDR4-3000
Storage: Crucial MX300 275GB M.2-2280 SSD
Seagate 2TB HHD (Already Own)
Video Card: EVGA GeForce GTX 1060 #GB SC Gaming
Or
Sapphire Radeon RX 480 4GB NITRO+
Case: Phanteks ECLIPSE P400S ATX Mid Tower Case
PSU: EVGA BQ 650W 80+ Bronze Certified Semi-Modular ATX Power Supply

Still haven’t decided on the Video card. Probably just get the one with the best sale this weekend. Any change suggestions would be appreciated. I am building this PC for some gaming. I will be doing a “medium” overclock. Main use will be Photoshop and just surfing the internet.

The case comes with two 120mm fans. 1 in front and 1 in back. Do I need more fans? If so how should they be configured? The case has a fan hub which I read somewhere could take 3 fans and has a LO, OFF, HI switch. The motherboard has 2 CPU headers and 3 Case fan headers, all 4 pin. I believe the Phanteks fans are all 3 pin but will plug into the board 4 pin headers if I read everything right. If that is the case, should I forgo using the case switch and plug them all into the board and use the MSI software to control them?

I know this has been long but I haven't built a computer from scratch since 4 MEGABYTES of RAM was the thing to save up for and I could really use some advice. Thanks in advance.

Two fans should be enough but if you see your system getting too warm then add more. One as intake/one as exhaust should be ok as long as they are good airflow fans. The case supports six fans though so it might be good to have two in/two out if you're overclocking. The non-cpu fan headers may be 4 pin but they are voltage controlled (3 pin) not PWM (4 pin) like the cpu_fan

Also, that m2 drive runs at SATA 6gb/s not pcie 3.0 x4 so unless space saving is your intention there's not much point

What would be the best way to control a 4 fan system then? I have read to set the intake fans as high as I prefer depending on noise and then set the exhaust fans at about 1/2 speed to create positive pressure. Will the MSI software allow me to do that if all are plugged into the MB?

Also, thanks for the heads up on the M.2 drive. I changed that to a Intel 600p Series 256GB M.2-2280 Solid State Drive. It's only $79.95 right now on Newegg.

Yeah you can still control fan speed and set curves via (ideally) your BIOS or MSI software, no need for controllers or anything.

Use 4 pin fans for the cpu_header and if you can non-pwm 3 pin fans for sys_fan headers. Some MSI boards can handle both types as long as you only plug one type into a header, but four pin in the system headers may run at full speed. Positive and negative pressure is over rated imo, and as long as you have sensible fan curves it'll be fine.

And much better choice of M2. The read speed on those NVME M2's are 3 times as fast as a SATA M2.

Thanks for the replies, Now all I have to do is wait for Friday!
