The Client
Ngozi Eze is a music producer and audio engineer operating out of a home studio in Surulere, Lagos. She produces Afrobeats and Afropop for independent artists and has engineering credits on several commercially released tracks. Her studio is a treated room in her apartment — proper acoustic panels, a decent monitoring chain, and the kind of obsessive attention to signal chain that separates serious engineers from hobbyists.
The problem in her setup was not musical. It was mechanical. Her production PC — a mid-tower desktop she'd built herself two years earlier — was audibly loud. Loud enough to register on a sensitive condenser microphone. Loud enough that she had to pause recordings when she needed to switch between sessions. Loud enough that it was becoming a genuine obstacle to her workflow.
The Challenge
Computer fan noise in a recording or mixing environment is measured in the tens of decibels — typically 35–45 dB for a standard desktop tower at moderate load. A treated room with good acoustic panels can get ambient noise down to 25–30 dB. In that environment, a loud PC is not background noise. It is the loudest thing in the room.
Ngozi's specific setup used Ableton Live as her primary DAW, with a large plugin library that included CPU-intensive instruments: Omnisphere, Kontakt with large orchestral libraries, FabFilter EQ and dynamics on most tracks. Her sessions averaged 60–80 active plugin instances on a final mix. This is real CPU load — the kind that spins fans up to high RPM and keeps them there.
She had already tried a budget "silent PC case" she found on Jiji — it was marketed as noise-reducing but made no measurable difference. She had also tried foam panels around the tower, which slightly reduced fan noise but created thermal problems that caused crashes in long sessions. She came to us having exhausted the cheap solutions.
The Consultation
Silencing a workstation without compromising performance is a design challenge. Noise comes from two sources: fans and vibration. Both require different solutions. We approached Ngozi's build as a system design problem rather than a parts selection exercise.
Our constraints were:
- Inaudible or near-inaudible at 1 metre — the distance from her desk to the mic stand
- Sufficient CPU performance to handle 80+ plugin instances in Ableton without buffer crackling
- Thermal stability: the machine must maintain performance without spiking fan speeds during long sessions
- Compatibility with her existing audio interface (Universal Audio Apollo Twin) and monitoring setup
We selected components based on noise profile first, then performance — an inversion of the usual priority order that only works when you understand the thermal envelope of each component.
The Build
Total build cost: ₦4.4 million.
- Case: Fractal Design Define 7 — purpose-designed for silent operation, with thick acoustic foam lining every panel, rubber-dampened drive mounts, and magnetic dust filters
- CPU: AMD Ryzen 9 7900X — 12 cores with an excellent performance-per-watt profile; less heat generated means less cooling needed means quieter fans
- RAM: 64GB DDR5 — audio production is RAM-intensive when loading large sample libraries; no paging to disk during sessions
- GPU: NVIDIA RTX 3060 — passive at idle, low-RPM fan at load; audio production is CPU-bound, not GPU-bound
- CPU Cooler: Noctua NH-D15 with both fans replaced with Noctua A15 PWM chromax — one of the quietest high-performance cooling solutions available; configured for low RPM with thermal headroom to spare
- Case fans: 3× Noctua A14 PWM, all on a PWM fan controller set to near-silent profile at typical session temps
- Storage: 2TB Samsung 990 Pro NVMe (silent — no moving parts) + 4TB Seagate IronWolf mounted on rubber vibration isolators
- PSU: Seasonic Prime Fanless TX-700 — completely fanless power supply, zero noise at all load levels
- UPS: APC Back-UPS Pro 1500 — pure sine wave, compatible with the Apollo Twin's power requirements
We measured the completed build at idle: 18 dB at 1 metre — below the threshold of perception in a quiet room. Under full Ableton load with CPU at 85%: 24 dB. Below the ambient noise floor of most treated rooms.
The Result
Ngozi measured the machine herself on her studio reference meter. She reported it as "basically the same as silence." More practically: she no longer pauses sessions when switching tasks. She no longer isolates the PC behind a partition. Her condenser microphone picks up nothing from the computer at normal working distance.
The performance gain was a secondary benefit she hadn't fully anticipated. Her previous machine was a Core i7-8700K with 32GB RAM — capable for its time but showing strain on large sessions. The Ryzen 9 7900X handles her largest Omnisphere and Kontakt sessions without buffer issues even at 128-sample latency. She's been able to open session sizes she previously had to split across multiple projects.
She has referred two other producers to us since the build. Both cited noise as the reason they reached out.
Key Takeaway
Silencing a workstation is not about buying the cheapest "quiet" case. It's about selecting every component for its noise profile and designing the thermal system to run well within limits. A properly silent workstation requires a fanless PSU, high-quality low-RPM case fans, vibration isolation on all mechanical drives, and a CPU cooler with enough thermal headroom to never need to spin fast. Done correctly, the result is a machine that is genuinely inaudible — not "quieter than before" but actually silent in a production context.
