Internal Cooling Fan Assembly
The pulsing is often caused by a failing Hall-effect sensor within the fan motor's PCB, which provides erratic RPM feedback to the motherboard's Embedded Controller (EC). If the EC cannot verify a stable RPM via the tachometer wire, it may cycle the voltage (PWM signal) to attempt to restart the motor or find a stable speed, resulting in audible pulsing. Replacing the physical fan assembly ensures a clean feedback loop between the motor and the thermal management logic.

High-Performance Thermal Interface Material
Degraded or improperly applied thermal paste leads to poor heat transfer between the CPU/GPU dies and the copper heat pipes, causing rapid, localized temperature spikes (transients). These spikes trigger the fan's 'aggressive' curve threshold prematurely; the fan ramps up, the spike subsides instantly, and the fan ramps down, creating a continuous cycle of pulsing speed.
