1. Check your system for dust buildup: Dust can cause an extreme decrease in air flow and create huge temperature increases inside your computer. Make sure to use an air compressor to blow out any dust buildup.
2. Make sure your case is ventilated: Make sure that the fans and vents in your case are unobstructed and working properly. Many cases come with fans installed, but if yours does not, consider adding one or two if needed. Also make sure that you have enough open space around the case to allow for adequate air circulation.
3. Clean the heatsink and replace the thermal paste: The heatsink is responsible for keeping the temperature of the processor cool. It is important to keep this clean and free from dust build up so it can do its job efficiently. It is also important to replace the thermal paste between the heatsink and the processor regularly. This will allow for better heat transfer and help keep your processor cooler.
4. Upgrade to a better cooling system: If all else fails and your temperatures are still too high, then you may want to consider upgrading to a better cooling system. This could include replacing your stock fan with a more powerful one, or adding liquid cooling to your system.
5. Check the power supply: Make sure that your power supply is functioning properly and not over-taxing the system. If your power supply is inadequate, then it won’t be able to provide enough power to your components and cause them to overheat. Make sure that your power supply is rated for the amount of power you are using in your system.
6. Monitor temperatures: To ensure that your temperatures stay within range, use temperature monitoring software such as Core Temp, or HWMonitor. These programs will allow you to monitor the temperature of each component and make sure they are staying within safe ranges.
7. Add additional case fans: Adding additional case fans can help improve air flow and reduce the temperature of your components. Make sure to set the intake fan(s) to draw cool air into the case, and the exhaust fan(s) to exhaust hot air out of the case.
8. Adjust voltage settings: If your computer is overclocked, then your components will produce more heat. Lowering the voltage settings can help reduce temperatures and allow the system to run cooler. It is important to only adjust the voltage settings if you are familiar with the process, as setting them incorrectly can drastically damage your system.
9. Check temperatures in BIOS: Checking the temperatures of the components in BIOS may help you identify whether the issue is hardware related, or software related. If the temperatures are lower in BIOS than they are in Windows then the issue is likely software related.
10. Troubleshoot drivers and software: If the temperatures of your components remain high even after checking the hardware, then there may be problems with the drivers or software installed on your system. Make sure that all of the latest drivers for your components are installed and that no unnecessary software is running in the background.
