These in-depth tests of the Founders Edition cooler look at the pressure distribution, flatness, power design and cables, and frequency stability for the NVIDIA RTX 4090 that just launched. We'll also talk about the 12-pin power cable and the adapter that NVIDIA provides to the 4x 8-pin cables, because Corsair recently called GN's comments on the cable "total BS" -- so we're responding. This covers Cyberpunk results differences in reviews as well. Our primary focus here is the mechanical and thermal design of the cooler, especially with Schlieren airflow imaging.
