videocardz - XFX launches Radeon RX 7900 XTX "Phoenix Nirvana" custom graphics card said:The cooler, called “Fengling Cooling Architecture 4.0,” uses 216 ultra-thin matrix fins and a high-low fin structure to improve airflow. Underneath, there is a vapor chamber covering the GPU and memory, as well as a Honeywell PTM 7950 phase-changing thermal pad known for high thermal conductivity. The card features an all-aluminum die-cast backplate.
Wow, beastly cooling. Will be interesting to see how that thing OC's.
