Windows 10 cpu fan gets noisy on full screen playing dvd

The sudden increase in fan noise on your device after a recent Windows update can be attributed to several factors. Here are a few common reasons for this issue and steps to address it: 1. Increased System Load: - The update might have caused increased system load, leading to higher CPU usage and consequently increased heat generation. This can trigger the cooling system to work harder, resulting in louder fan noise. 2. System Resource Usage: - Check Task Manager to monitor resource usage (CPU, memory, disk). Identify any specific processes consuming high resources that could be leading to increased fan activity. 3. Dust Buildup: - Dust accumulation inside the system can hinder proper heat dissipation, causing the CPU to heat up more, resulting in increased fan noise. Consider cleaning the internal components to improve airflow. 4. Thermal Paste: - The thermal paste between the CPU and the heat sink may have degraded, affecting the heat transfer efficiency. Consider reapplying thermal paste to ensure proper cooling. 5. Power Settings: - Ensure your power plan settings are appropriate. High-performance settings can cause the system to work harder, increasing fan noise. Opt for balanced power settings to reduce system load. 6. Background Processes: - Disable unnecessary startup applications and background processes that could be consuming system resources and causing the fans to work harder. 7. Driver Updates: - Ensure all drivers are up to date, especially graphics and chipset drivers. Outdated drivers can sometimes cause system inefficiencies, resulting in increased fan noise. 8. Cooling Pad: - If you're facing persistent overheating issues, consider using a cooling pad to assist in heat dissipation and reduce the workload on internal fans. By addressing these factors and monitoring your system's performance, you should be able to reduce the fan noise caused by the recent Windows update and restore normal operation.
