First time setting custom fan curves in iCUE Link, 140mm red exhaust & blue intake fans. Preparing for RTX 5090 Astral OC (quiet but cool) need advice.

Hello

I have a 11x 140mm Corsair LX and LX-R fans:

Exhaust: (AIO up top + top rear Fan)

Intake: (Bottom + back + bottom rear)

(See photo of pc on my profile)

I’m installing an ASUS RTX 5090 Astral OC in a few days. so I want decent cooling but prioritize quiet operation during normal use and gaming.

Questions for you:

  1. What curve do I set the fans ?
  2. What temperature source should I use in iCUE Link for the case fans? (GPU temp, CPU temp, or something else?)
  3. Should intake (blue) and exhaust (red) have different curves?

Thanks a lot, any advice to get me started would be awesome!
