That is an absolutely insane amount of power for 7nm. We all thought Navi 5700XT was insane with 200 Watts power (not TDP at that)
What I find really curious is, if it runs that hot, WHY USE A SINGLE FAN? Are we returning to leaf blower designs again? More fans = more airflow = better temps/less noise.
What's also curious is the use of an axial fan as opposed to a centrifugal/squirrel cage fan typically found on blower designs. If you have to push air through a lot of fins, there's a high drag factor, and you need static pressure. This is an axial fan's weak point. Axials are more about velocity than pressure. (Not that you can't make them high pressure. It's just harder to do with multiple sweep blades and higher RPM.) Centrifugal fans are much more efficient in this regard.
