Noctua is known for making high-end, high-quality fans and air coolers, which it has been doing for over 20 years, recently expanding into AIOs. However, it appears that there were a few questions regarding its PC case compatibility database, which some PC DIYers say don’t match the data from the manufacturer’s website. The company cleared this up in a blog post, saying that it has undertaken its own measurements and it has determined that 56 of the more than 100 cases it has tested showed significant deviation from the details officially listed online.
The company gave two diverging situations of inaccurate official measurements. The first one is when the case is larger than what is actually written, which would allow PC builders to attach a larger cooler. Noctua said that the deviations aren’t minor, either. For example, the NZXT H2 Flow case is listed as being compatible with a maximum 75mm CPU cooler height, but the actual case can accommodate an air cooler up to 79mm. There’s also the Thermaltake TR100, which is 2.7mm larger than what the Thermaltake website says, and the Corsair Frame 4000D, which gives you 10mm of extra clearance.
