Fan Layout for NZXT H7 Flow (2024)?

[Bionic23]

I just wanna know how many case fans i need to get, and where to put em. I'm pretty sure it comes with 3 3-pin fans, but idk if I should use them. The case fans I plan on using are the Thermalright TL-C12C's. If someone could just edit the photo I gave to show where the fans should go that would be great. Specs are as follows:

 

- CPU: Ryzen 7 9700x

- CPU Cooler: Thermalright Phantom Spirit SE 66.17 CFM CPU Cooler

- Mobo: ASRock B850 LiveMixer WiFi ATX AM5 Motherboard

- RAM: TEAMGROUP T-Create Expert 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory

- SSD: WD Black SN850X 2TB

- GPU: Asus PRIME OC Radeon RX 9070 XT

- Case: NZXT H7 Flow (2024)

- PSU: NZXT C850 (2024) PSU

- Fans: Thermalright TL-C12C (idk how many yet)

I'm assuming you're on a tight budget, so every fan counts. This would be what I'd do. 3 intakes in the front, 1 exhaust in the back, and 1 exhaust on top. Try keeping your PSU facing down if your case has holes for it at the bottom. This is so your GPU isn't fighting your PSU for fresh air. It looks like the case has plenty of space for intake on the bottom so long as it isn't on a carpet or something.

Just looked up the case. It looks like the PSU can be put sideways? If that's the case (pun not intended), you could put a fan at the bottom to give more fresh air to your GPU. I'd imagine (if budget isn't an issue) the ideal fan setup would be something like this. Keep your CPU fan intake in the same direction as the front intake.

Would you recommend using the stock fans that came with the case?

I don't see a problem with them, but from what I see online, the case only comes with three. I'd feel more comfortable with at least 1 or 2 more fans.

Buy the case and use the default fans first and see if you need more later.

ya some cases have ok stock fans some don't so see first. but if the rpm are different it can be a bit more to setup different fan curves for each. but that's more for fast loud fans. but if you wanted to min max airflow you have different rpms anyway but o mean who dose that. 1c woopy...

I have that case.

 

Installed my AIO as front intake.

Installed 3x P12 PWM PST on the bottom as intake, installed 3x P12 PWM PST on the top as exhaust.

Done.

The NZXT fans goes to the old PC.

 

Doing fine so far.
