What happened
Noctua's internal compatibility team physically measured CPU cooler clearances across more than a hundred PC cases and found over half had published specs that were wrong, with errors ranging from -3.5mm to +10mm. This means a significant portion of cases on the market may not actually fit the coolers their documentation claims to support.
Why it matters
If you spec or buy PC cases for workstations or local assembly, don't trust manufacturer clearance figures blindly—verify with Noctua's compatibility database or physical measurement before committing, especially for tight-fit builds where a few millimeters determines whether a cooler fits.
Discussion angle
Whether hardware spec sheets from vendors are reliable enough to build on without hands-on verification, and how this maps to trusting specs in software/infra procurement.
