Building a PC? Don't trust the specs.

Noctua’s rigorous testing reveals over 50% of tested cases feature inaccurate CPU cooler clearance data. With errors ranging from -3.5mm to 10mm, your dream cooler might not fit.

Stop relying on manufacturer marketing—physical measurements prove these numbers are dangerously unreliable. Always verify manually before you buy to avoid a catastrophic, non-closing build nightmare.
