Why we tune every build for decibels before frames

Silence is not the absence of performance. It is a thermal budget spent intelligently — and it starts with accepting that the last 4% of benchmark scores cost 40% of the noise. Our tuning philosophy is simple: sacrifice the 4%, keep the 40%.

Every INPUT system idles at or below 24 dB, measured at 50 cm from the front intake. That number is not aspirational; it is a shipping gate. Builds that miss it get their fan curves rewritten until they pass, and roughly one in twenty needs a physical change — a different cooler mount, a moved exhaust, a PSU that ramps later.

The biggest lever is one nobody markets: hysteresis. Cheap fan curves ripple — they spin up, overcool, spin down, heat soak, and repeat, which your ear reads as twice as loud as a steady state. Our curves hold minimum speed until 78°C, then ramp in a single smooth arc. The CPU runs 4°C warmer. You cannot hear 4°C.

Airflow geometry is the second lever. Positive pressure — more intake than exhaust, filtered — keeps dust out and lets two large intake fans do the work of four small ones at half the RPM. Felt, foam, and closed-cell gaskets around panel seams kill the 1–2 kHz hiss that tiny gaps generate at load.

The result is a machine that is measurably slower in synthetic peaks — 2 to 4% — and immeasurably better in the hundred hours you spend next to it each month. We know which one we would rather sell you.
