Monitor Hardware Performance and Temperature

To enable PC Game Booster to monitor and alert about hardware temperature, follow these steps:

1. Open PC Game Booster and go to Settings.
2. Navigate to the Misc tab.
3. Under the Hardware Monitor section, select the checkbox labeled "Show a warning when a hardware temperature exceeds a specific value".
4. Select the types of hardware you want to monitor, such as CPU, GPU, hard disk, and Motherboard.
5. Set the safe threshold temperature for each selected hardware component.

Once enabled, PC Game Booster will automatically alert you whenever any monitored hardware exceeds the defined safe temperature threshold — helping you prevent overheating and protect your gaming PC from thermal damage.

By default, PC Game Booster displays hardware temperatures in Celsius. To switch to Fahrenheit, follow these steps:

1. Open PC Game Booster and go to Settings.
2. Navigate to the Misc tab.
3. Under the Hardware Monitor section, select the checkbox labeled "Display temperature in Fahrenheit".

Once selected, all hardware temperature readings — including CPU, GPU, hard disk, and motherboard — will immediately appear in Fahrenheit instead of Celsius.

Safe operating temperatures vary by component type. Below are the recommended threshold ranges for modern hardware based on normal operating conditions:

CPU (Processor)

• Idle: 30°C ~ 45°C
• Load: 60°C ~ 85°C
• Alert: Set warning at 85°C - 90°C to avoid thermal throttling

GPU (Graphics Card)

• Idle: 30°C ~ 45°C
• Gaming: 65°C ~ 85°C
• Alert: Set warning at 85°C - 90°C

Hard Disk Drive (HDD)

• Normal: Up to 50°C
• Maximum: 60°C
• Alert: Set warning at 50°C - 55°C

SSD / NVMe Drive

• Normal: 30°C ~ 70°C
• Maximum: 70°C
• Alert: Set warning at 65°C - 70°C

Motherboard

• Normal: 35°C ~ 50°C
• Maximum: 60°C
• Alert: Set warning at 55°C - 60°C

When any monitored hardware component exceeds the safe temperature threshold you have set, PC Game Booster will immediately display a hardware temperature warning. This warning clearly shows:

• What type of hardware is overheating (e.g., CPU, GPU, Hard Disk, or Motherboard)
• The current temperature of that hardware component

The warning dialog offers you two options:

1. Continue — Clicking the OK button allows PC Game Booster to continue monitoring your system. The software will check the temperature again at the next internal interval and alert you again if the hardware remains above the safe threshold.
2. Ignore — Clicking the Ignore button tells PC Game Booster to ignore this specific hardware type for the remainder of the current session. No further warnings for this component will appear until you restart PC Game Booster.

This alert system helps you stay informed about potential overheating risks while giving you the flexibility to temporarily dismiss warnings when you understand the situation — all without interrupting your gaming experience.

PC Game Booster offers a wide range of real-time information about your current system and hardware performance — including voltage, temperature, CPU cores activity, fan speeds, and more — all from the same interface.

To access this information through the main interface:

1. Open PC Game Booster.
2. Navigate to the System Diagnostics tab.
3. Select Performance.
4. This will open the System Performance dialog, which contains all current system and hardware performance information in one place.

To access the System Performance desktop widget:

1. Right-click on the PC Game Booster icon in the system tray.
2. Click on System Monitor.
3. This will open the desktop widget that displays real-time resource and hardware information.

Antivirus programs may flag PC Game Booster because it uses Libre Hardware Monitor — an open-source library that relies on the WinRing0 kernel driver to read hardware sensors. The flag is triggered by the driver itself, not because PC Game Booster contains malware.

The WinRing0 driver has a documented vulnerability (CVE-2020-14979). Microsoft began flagging all programs that use this driver — including MSI Afterburner, FanControl, and OpenRGB — not just PC Game Booster.

PC Game Booster is fully safe to use since it does not include any adware, spyware, or telemetry. Antivirus software may flag the WinRing0 driver due to its known vulnerabilities, but this does not indicate that PC Game Booster is malicious. In fact, the risk associated with this driver is minimal for home users.

After monitoring your hardware temperatures with PC Game Booster, if you notice high CPU or GPU temperatures, you can take the following measures to lower them:

1. Clean dust from fans and vents

Dust buildup on CPU, GPU, and case fans restricts airflow and traps heat. Regularly clean your PC's interior using compressed air to remove dust from fans, heatsinks, and vents — improving cooling efficiency and lowering temperatures.

2. Upgrade the CPU fan or cooler

If your stock or existing CPU cooler is insufficient, consider upgrading to a higher-performance air cooler or liquid cooling system. A better cooler dissipates heat more effectively, keeping your CPU temperatures under control during intense gaming sessions.

3. Apply new thermal paste

Thermal paste degrades over time, losing its ability to transfer heat from the CPU/GPU to the cooler. Reapplying high-quality thermal paste can reduce temperatures by several degrees, especially on older systems.

4. Check processes that cause high CPU or GPU usage

Use PC Game Booster or Task Manager to identify background processes consuming excessive CPU or GPU resources. Terminate or disable unnecessary applications and services that cause high usage — reducing workload and lowering temperatures.

5. Switch to a balanced power plan

High-performance power plans force your CPU and GPU to run at maximum performance levels constantly — even when not needed — leading to unnecessarily high temperatures. Switching to the Balanced power plan in Windows allows your components to dynamically adjust performance based on workload, significantly reducing heat generation during idle or light tasks while still delivering full power when gaming.
