Hey everyone,

I watched the Gamers Nexus review of the HAVN HS 420 case, and I think it looks amazing, I’m planning my first custom watercooling build using this case, and I could really use some advice. My goal is to have a system with two 420mm intake radiators, but I’m unsure if my setup ideas are optimal.

Radiator Layout:

I’ve attached a photo of my planned layout in the case. My idea is to have fresh air coming in from the bottom and side (both 420mm Radiator), with exhaust at the top. Do you think this is the best airflow setup for cooling performance? Also, what should I do with the two fan mounts on the left side—should I use them for more intake or exhaust?

Planned Components:

After doing some research on watercooling parts, here’s what I’m currently thinking of using:

  • Reservoir & Pump: ULTITUBE D5 200 Reservoir with D5 PWM Pump
  • Radiators: Alphacool NexXxoS ST30 Full Copper 420mm Radiators (x2)
  • Fans (Intake): Noctua NF-A14x25 G2 (x6) (on the radiators)
  • Fans (Exhaust): Noctua NF-P14s Redux-1500 PWM, 140mm (x3) (at the top)
  • GPU Block: Bykski Intel Arc A770 (I-GNA770-X)

I haven’t bought any parts yet, so if you have suggestions for better components, I’m all ears, For fittings and tubing, I’m still undecided any recommendations would be appreciated.

For context, I’m currently on an AM4 system but planning to upgrade to AM5 or LGA 1851 soon.

Thanks in advance for any feedback, I Appreciate your help.
