1️⃣ Common Causes
- 🔥 High CPU/GPU usage — gaming, rendering, crypto mining, or malware
- 🕸️ Dust buildup blocking airflow and fan efficiency
- ⚙️ Outdated BIOS, firmware, or drivers affecting fan control
- 🌡️ Improper thermal paste or poorly seated coolers
- 💻 Laptops: blocked vents, soft surfaces, or insufficient cooling design
2️⃣ Basic Troubleshooting (Windows, Mac, Linux)
- Shut down and clean fans, vents, and heatsinks from dust
- Ensure PC/laptop is on a hard, flat surface for optimal airflow
- Check running processes:
- Windows: Task Manager (Ctrl+Shift+Esc)
- Mac: Activity Monitor
- Linux: System Monitor, `top`, or `htop`
- Close high CPU/GPU applications or background tasks
- Update operating system, BIOS/UEFI, and all drivers
3️⃣ Advanced Steps
- 📊 Monitor temperatures:
- Windows: HWMonitor, Core Temp, Ryzen Master, Intel Extreme Tuning Utility
- Mac: iStat Menus
- Linux: `sensors` or Psensor
- Check BIOS/UEFI fan curves; set custom RPM profiles for CPU/GPU/fans
- Reapply thermal paste on CPU/GPU if temps remain high
- Upgrade cooling: better air coolers, additional case fans, or AIO liquid coolers
- Scan for malware or background apps overloading CPU/GPU
4️⃣ Tips for Reducing Noise
- 💡 Keep system in a cool, ventilated environment
- 💡 Clean dust every 3–6 months
- 💡 Use software-controlled fan curves for efficiency
- 💡 Laptops: avoid soft surfaces like beds/couches and use cooling pads if needed
📊 Fan RPM & Temperature Reference
| Component |
Normal Temp |
Fan RPM |
Notes |
| Intel CPU (14th/15th Gen) | 35–75°C idle, 85–100°C load | 600–3500 RPM | Modern CPUs boost fans aggressively above 80°C |
| AMD Ryzen 7000/9000 | 35–75°C idle, 85–95°C load | 600–3600 RPM | 3D V-Cache CPUs may run slightly warmer |
| GPU: NVIDIA RTX 4000/5000 | 30–70°C idle, 75–95°C load | 600–4000 RPM | Fans curve depends on GPU model and case airflow |
| GPU: AMD RX 7000/9000 | 35–75°C idle, 80–95°C load | 600–4200 RPM | RDNA 4 GPUs optimize fan curves automatically |
| Laptop CPU/GPU | 40–85°C idle, 90–100°C load | Fan depends on model | Use cooling pads for sustained heavy workloads |
📌 Quick Summary Table
| Step |
Action |
| 1 | Clean fans and vents |
