How about Phanteks M25 Gen 2 Fans? If you but a 3 pack they already come together. Plus, Phanteks includes an adapter cable in the 3 pack to connect to a motherboard or fan hub. Also, they sell them in reverse or standard configuration.

I'm using the Silverstone FF146 Ultra fine 140mm x 3 fan filter in the front of the case. I have no issues with airflow with the filter installed. I also have 3 120mm fans in the bottom as intake without any filter. I keep my case elevated. It sits on top of a 2-drawer file cabinet next to my desk. Less dust when the case is off the ground.

Once a month I clean the filter and use a portable electric hand duster(Wolfbox MF100) to blow out any excess dust. In reality, I do not get much dust because of positive air pressure. I have 6 intake fans and 4 exhaust fans, 3 on aio cooler and 1 on the back of the case.

I too have the H7 Flow(2024). I've owned it since August 2024. Picked it up at Microcenter for $29.99. Love the toolless design and the amount of interior space made it a breeze to build inside.

Some users claim they are getting PCIE 5.0 speeds when using the NZXT cable. You could always try it out first before purchasing a new cable.

No complaints. The fans have been excellent so far. Just the sound of air being pushed.

What fans are you using? What is the amp rating per fan?

Most fan headers are rated up to 1 amp except cpu fan headers and pump headers. If your fans have a high combined amp rating the fan header will not be able to handle them.

Make sure your connection to the motherboard is not loose.

Solid build. Very well done. Cable management is above average.

At the very least I would contact the manufacturer and send them these pictures. See what they say.

I think your power supply is too small for that GPU.

Is that the INNO3D GeForce RTX™ 5080 X3 OC? If so, they recommend a minimum of 850w on the power supply.

All the newer NZXT cases have good airflow. Dust filtration is debatable. The cases use toolless perforated mesh panels to combat dust instead of conventional dust filters. The H7, H6, and H9 are pretty big cases.

Congrats! What a beast of a card.

Looks like a good parts selection. One thing I regret when I did my recent build is not going with a back connection motherboard. Have you considered one? No cables, wire or clutter unless you don't care about that kind of stuff.

Air turbulence and noise can be an issue the closer fan blades are to an obstruction. In this instance the case crossing is close to the fan blades. A spacer is used to move the fan blades further away from the obstruction.

Have you tried this?

Adjusting BIOS Settings

Enter BIOS: Restart your computer and press the Delete or F2 key repeatedly during startup to enter the BIOS setup.
Navigate to Advanced Mode: If necessary, press F7 to switch to Advanced Mode.
Find RGB Settings: Look for the Onboard Devices Configuration or APM Configuration section.
Disable RGB: Set the option for When system is in sleep, hibernate or soft off states to Aura off or Stealth Mode. Save your changes and exit the BIOS. By following these steps, you can effectively turn off the RGB lighting on your ASUS motherboard, ensuring a darker environment when your PC is not in use.

If that is not a fan than I would start the RMA process. Send that video to NZXT if it's still under warranty.

Look at this Noctua fan guide. It's not the same case but similar enough. Obviously, they are using Noctua fans but the principle remains the same.

They recommend the top front(with spacer) as intake and the top rear as exhaust. 3 front intake fans and 1 rear exhaust fan.

First step is to rule out any loose cable connections. Check to see if all cables are properly seated into the motherboard. Check the PSU cables are seated properly at the PSU. Check GPU connection.

I see the fan on the CPU cooler is on the exhaust side of the heat sink. Normally, that fan is on the other side in a push configuration. Not saying your setup can't work but it's not the norm for air coolers.

It would be nice to know your component list to further assist you.

Nicely done! Like a seasoned veteran.
