Could a failing CPU and GPU Replacement Cooling Fan Pair cause the DELL G15 GAMING LAPTOP to have symptom: Fan Noise Loud?

The G15 series utilizes high-RPM fans that are susceptible to bearing wear and spindle wobble over time. Grinding or excessive buzzing occurs when the lubricant within the bearing housing degrades or is contaminated by micro-particulates. Replacing the full fan assembly restores the system to factory acoustic specifications.

Could a failing High-Performance Thermal Interface Material cause the DELL G15 GAMING LAPTOP to have symptom: Fan Noise Loud?

If the fans are spinning loudly without mechanical grinding, the system is likely compensating for thermal saturation. Factory thermal paste can dry out or 'pump out' due to thermal cycling, leading to poor heat dissipation. Fresh TIM reduces the delta between the core temperature and the heatsink, allowing the BIOS to lower the fan duty cycle.

Could a failing Compressed Air Duster cause the DELL G15 GAMING LAPTOP to have symptom: Fan Noise Loud?

Dust accumulation in the high-density fin stacks of the G15 heatsinks increases airflow resistance. This forces the fans to spin at higher RPMs to move the same volume of air. Clearing these obstructions restores the intended thermodynamic efficiency of the cooling loop.

What is the most likely root cause for a DELL G15 GAMING LAPTOP with symptom: Fan Noise Loud?

The G15 series utilizes high-RPM fans that are susceptible to bearing wear and spindle wobble over time. Grinding or excessive buzzing occurs when the lubricant within the bearing housing degrades or is contaminated by micro-particulates. Replacing the full fan assembly restores the system to factory acoustic specifications.

System Nominal

Under high-performance gaming loads, it is an engineered requirement for the fans to reach 45-55 decibels to dissipate the heat generated by the 100W+ TDP components. If the noise occurs only during gaming and is a clean 'whoosh' of air, the system is operating within its designed thermal parameters.
