Context​

I was working on an open-source "web 3.0" project I shall not name with crazy stupid long compilation times (close to 10-20 minutes), the whole software stack/architecture was wrong but well... it's way too deep into sunk-cost fallacy. I got tired off my 5yo laptop slow CPU and bus, even with 32GB RAM.

So I got dumb: I wanted a small box that packs the most powerful CPU available for the socket AM4 with a motherboard that supports ECC memory in an ITX case. And why not use a 120mm quiet AIO?

Note: be angry at hardware makers like to Linus Torvalds and use ECC memory if you can.

Hardware​

CaseDAN A4-SFX v4.1
MoboB550 Phantom Gaming-ITX/ax
CPUAMD Ryzen 9 5950X
GPUMSI Radeon RX6500XT Mech 2X OC (172mm)
RAMSamsung 2x16GB DDR4-3200 CL22 ECC unbuffered Dual Rank (1x8Go)
SSDSamsung 980 Pro M.2 1TB (NVMe)
AIOCorsair Hydro H60 (120mm)
PSUCorsair SF600 Platinum (125x63.5x100mm)
CablesCableMod 24Pin ATX (150mm) + 8Pin EPS (300mm) + SATA Power (100mm)
FanNoctua NF-A12x15 PWM (120x15mm)
Fan grid+filterSilverstone (120mm)

Build​

Tight fit but overall ok, I wanted to use a passive PSU at first (Silverstone SST-NJ450-SXL) but it was a stupid idea. Switched to a more compact Corsair SF600.
  • I had to cut a 120mm square into the side panel to have the radiator further away from the PSU, you can see there is a ~4mm gap between them. The fan is attached to the side panel a grid+filter on top
  • The radiator sits at the bottom of the case, there is a ~1mm gap with the front USB-C port
  • I ordered custom length cables from CableMod because otherwise it was a compacted mess and the airflow was quite bad
  • There is ~2mm extra room at the end of the GPU

BIOS settings​

  • CPU: ECO mode (less power drawn => lower temperatures)
  • AIO pump: maximum (4000+ RPM)
  • AIO radiator fan: auto (~1100 RPM average)
  • ECC: enabled

Notes: I am using Ubuntu 20.04 LTS, I can control all fans properly between the UEFI settings for the CPU/pump and Radeon Profile for the GPU. It's quite silent.
  • CPU idle temperature: <50°C (~1200RPM fan minimum speed)
  • GPU idle temperature: <50°C (10% fan minimum speed)
