Route smart, don’t over-tighten

Use rear channels and grommets; keep cables flat, not bunched.
Run GPU power straight with gentle bends; avoid blocking front intakes.
Leave slack near connectors to reduce strain and ease swaps.

Fan layout that works

Baseline: Two front intake + one rear exhaust. Add top exhaust for hot GPUs/CPUs.
Positive pressure: Slightly more intake than exhaust helps reduce dust.
Keep front filters clean; vacuum monthly if you have pets or carpet.

Airflow checks

Feel for warm pockets near GPU/VRM. If present, add a front fan or raise fan curve.
Intake temps high? Remove unused drive cages, open front panel vents, or step up fan RPM.
Bundle excess PSU cables behind the tray or use a PSU shroud.

When to add fans or change cases

If you’re still thermal throttling after cleaning and retiding cables, add a quality 120/140mm intake. For >300W GPUs and overclocked CPUs, prefer cases with mesh fronts and space for 240–360mm radiators or tall air coolers.
