120mm PWM High-Static Pressure Fan
The CPU Fan Error is triggered by a lack of an RPM signal on the motherboard's dedicated header. This occurs when the fan's brushless DC motor fails or the internal Hall effect sensor stops pulsing the tachometer wire. Replacing the fan ensures a consistent square-wave frequency is sent to the BIOS, satisfying the boot-time safety check.

High-Performance Thermal Compound
During the process of addressing a CPU fan error, the heatsink or AIO pump block must often be reseated. New thermal interface material is required to ensure microscopic air gaps between the CPU integrated heat spreader (IHS) and the cooler base are eliminated, preventing localized hotspots and thermal throttling.

PWM Fan Extension/Splitter Cable
In systems with large GPUs like the RX 7900 XTX, cable tension or improper routing can lead to the CPU fan header becoming unseated or the wire being pinched. A high-quality braided extension ensures a secure, low-resistance connection between the cooling fan and the motherboard header, preventing intermittent signal loss.
