← ScienceWhich outcome occurs when exceeding the thermal design power limit in a CPU heatsink?
A)Decreased transistor switching efficiency
B)Permanent CPU performance reduction✓
C)Increased frequency instability margin
D)Improved thermal paste effectiveness
💡 Explanation
Permanent CPU performance reduction occurs because thermal throttling engages, limiting frequency and voltage to prevent critical temperature exceedance via negative feedback; therefore performance degrades irreversibly, rather than merely reducing efficiency under voltage thresholds.
