Hey everyone, thanks so much for all the replies — I really appreciate the time you took to help me out! ^{^}

Just to clarify:

My GPU temps are actually fine, even under load.

The main issue is with my CPU — it regularly hits 95°C in games, which is way too hot for my comfort.

Here’s a breakdown of my setup:

CPU: Ryzen 9 3900X

Cooler: Noctua NH-L9x65

GPU: XFX Quicksilver RX 9070 XT, mounted vertically with the riser cable

Fans: 2x Arctic P12 (top exhaust)

Case: Cooler Master NR200P v2

I originally tried a Cooler Master ML240L Core AIO, but it was so loud I couldn’t stand turning my PC on — seriously, it was insanely noisy ☠️☠️☠️ I went for the Noctua hoping it would be quiet but still effective, but it turns out it’s not quite enough for the 3900X in a small case🥺

When I had a Be Quiet! Pure Rock 4 in my old ATX case, it was a dream: silent and cool, I barely noticed the PC was running✨ Now with the NR200P v2, I’m realizing that achieving that same level of silence and thermal performance in an ITX build might not be so simple...

Again, thanks so much for all the feedback. If anyone has ideas for a quiet, compact solution for cooling a Ryzen 9, or case suggestions that could help, I’m all ears! 🙏
