01.Introduction: The Invisible Enemy
Your PC doesn't warn you "I'm hot." It simply starts to lag. When the CPU reaches 95°C (Intel) or 90°C (Ryzen), the clock drops from 5.0GHz to 3.5GHz. This is called Throttling.
Don't do it Manually.

02.Chapter 1: Monitoring (Diagnosis)
HWMonitor
1. Download and run CPUID HWMonitor.
2. Play for 20 minutes.
3. Alt-Tab and check the "Max" column.
- CPU Package: If it's > 90°C, you have a problem.
- GPU Hotspot: If it's > 105°C, there's likely a problem with the thermal paste on your graphics card.
03.Chapter 2: FanControl (The Best Tool)
Forget BIOS-based control. Use FanControl (open-source).
It detects all the fans in your PC and allows you to create mixed curves.
Example: You can make the case fans speed up based on the MAX temperature between the CPU and GPU. This way, if EITHER one gets hot, the air circulates more efficiently.
04.Chapter 3: Creating the Ideal Curve
- Up to 50°C: 30% or 0% (Silence mode).
- At 70°C: 60% (Audible but acceptable for gaming).
- At 85°C: 100% (Emergency turbine mode).
Enable "Hysteresis" (Delay). This prevents the fan from oscillating (Vroom... Vroom...) if the temperature jumps quickly between 69°C and 71°C.
A1.Chapter 4: Airflow Strategy
- Positive Pressure: More air entering than exiting. Good for avoiding dust (excess air exits through cracks). - Standard Setup: Front/Bottom fans should blow air IN. Rear/Top fans should blow air OUT (hot air rises). - CPU Air Cooler: The fan should blow TOWARDS the heatsink and towards the back of the case.
A2.Chapter 5: AIO Water Cooler (Pump Speed)
The Water Cooler pump should always run at 100% or close to it. Pumps are usually silent and need to circulate water constantly.
Only adjust the speed of the radiator fans.
If the pump stops, the CPU hit 100°C in 5 seconds.
A3.Chapter 6: Thermal Paste and VRAM
Thermal paste dries out. If your PC is 3 years old and running hot, replace it.
In GPUs, use Thermal Pads on VRAM chips. GDDR6X memories (RTX 3070 Ti+) reach 110°C easily if the pads are poor.
A4.Chapter 7: Undervolt (Better than Fans)
The most efficient way to lower temperature isn't setting fans to 100% (noisy), but performing an Undervolt on the CPU/GPU.
Fewer Volts = Fewer Watts = Less Heat.
Check our Afterburner and BIOS guides for step-by-step instructions.
Chapter 8: Dust Maintenance
Dust in the filters blocks air. Your PC suffocates.
Clean dust filters every 3 months.
Use compressed air to clean the heatsink fins.
Chapter 9: Ambient Temperature
If your room hits 40°C in summer, your PC will suffer.
PC temperature is always Ambient + Delta.
The best cooler won't help if the air coming in is already hot. Open a window or use air conditioning.
Chapter 10: Notebooks and Cooling Pads
Gaming Notebooks REQUIRE a cooling base or at least lifting the rear with a support (don't block the air intake).
A 5cm gap underneath can reduce temperatures by 5°C.
Don't do it Manually.
