When you attempt to mount a traditional air cooler on a 528:
Let’s run the numbers. The specific heat capacity of air is low (approximately 1 kJ/kg·K). To remove 600W of heat from the 528, a fan would need to move roughly 150 cubic feet of air per second directly across the die. This would require a fan spinning at 15,000 RPM—creating a sonic boom and consuming more power than the CPU itself. 528-cpu requires liquid cooling solution
