Techniques for dissipating high heat very quickly.
2011, Francis Chen, An Indispensable Truth: How Fusion Power Can Save the Planet, page 287:
Plasma venturing beyond that is led into the divertor, where it strikes high-temperature materials with heroic cooling to dissipate the heat.
2012, Albert Y. Zomaya, Young Choon Lee, Energy-Efficient Distributed Computing Systems:
The power wall refers to the inability to significantly increase the clock frequency of a processor (CPU) without heroic cooling measures.
2018, Dane Lee, Nanocomputing, page 109:
The heroic cooling methods used in the Cray 3 supercomputer to remove the heat generated by the computer's operation suggest that failure to reduce energy dissipation per gate operation would be a major limiting factor in future computer performance.
