Finally dialed in my SFF build and hit a quiet + high-efficiency sweet spot.
System is essentially silent under load while exceeding stock performance.
Parts
- AMD Ryzen 7 9800X3D 4.7 GHz 8-Core Processor
- Custom Cooler Master CPU cooler (included with case)
- ASUS ROG STRIX B850-I GAMING WIFI Mini ITX AM5 Motherboard
- TEAMGROUP T-Create Expert 32 GB (2 x 16 GB) DDR5-6000 CL30
- WD_BLACK SN7100 2 TB M.2-2280 PCIe 4.0 x4 NVMe SSD
- ASUS PRIME OC GeForce RTX 5080 16 GB
- Cooler Master NCORE 100 AIR S
- Cooler Master V850 SFX Gold 850 W (fully modular)
- Cooler Master MOBIUS 120 mm (63.1 CFM)
Tuning (daily setup)
- CPU: PBO enabled, Curve Optimizer -20 all-core
- GPU: 950 mV / 2800 MHz / 90% power limit
Fan strategy (critical for SFF)
- Rear exhaust → tied to GPU temp (primary heat source)
- Top exhaust → tied to CPU temp (support airflow)
- CPU fan → smoothed midrange curve (no ramp spikes)
Results
- Cinebench 2024: 1342 (vs 1251 stock)
- Max temp: ~90°C
- Steel Nomad:
- Stock: 8554
- Daily: 8674
- Peak (95% PL): 8704
- Max temp: ~75C
Temps (real gaming)
- GPU: ~68–72°C @ full load
- CPU: ~62–65°C
FPS (4K, max settings)
- Crimson Desert: ~100–110 FPS
- Battlefield 6: ~120+ FPS
Final thoughts
Near-silent SFF build with top-tier performance.
Undervolting on both 9800X3D and RTX 5080 is extremely effective.
GPU undervolt also eliminated coil whine.
Tuning is focused on acoustics and efficiency, not max OC — and it shows.
