When running high-performance software applications or gaming, your CPU can heat up considerably, hence, the need for thermal paste. Thermal paste, also known as thermal compound or heat sink compound, improves the conduction of heat between the CPU and a heatsink. However, over time, the thermal paste can degrade or dry out leading to inadequate cooling. That is why it’s imperative to replace it, particularly on age-old CPUs, to maintain optimal temperature control and boost overall performance.
#1: The Preparatory Stage
Before you begin, it is essential to gather all the necessary tools. This includes 99% isopropyl alcohol, microfiber cloth or coffee filters, a small flat-head screwdriver, high-quality thermal paste, and non-static workstation if possible. Besides, you should ground yourself to avoid causing electrostatic damage to your CPU.
#2: Shut Down and Disconnect
Start by shutting down your computer entirely and disconnecting all peripherals from the system unit. Then, unplug the power cord from the back of the computer to prevent damage. It is recommended to wait for about 15 to 30 minutes to allow the CPU and other components to cool down.
#3: Opening Up to Access the CPU
Next, remove the computer case or laptop shell to expose the internals. Normally, the casing is held in place by screws at the back of the computer, which you can unscrew using a screwdriver. If you’re unsure, refer to your computer’s user manual.
#4: Removing the CPU Fan/Heatsink
Once the casing is off, locate the CPU, which typically has a large metal or plastic fan sitting on top of it. This is your heatsink. Gently unlock and lift the heatsink off the CPU. Use caution as it can be firmly in place due to the old thermal paste.
#5: Cleaning the CPU Surface
Now that the CPU is visible, use a coffee filter or microfiber cloth dampened with isopropyl alcohol to clean off the old thermal paste. Wipe gently but thoroughly until the surface is free of the old paste. Repeat the process on the base of the heatsink if it was previously in contact with thermal paste.
#6: Applying the New Thermal paste
Now it’s time to apply the new thermal paste. Ensure you choose high-quality and reliable thermal paste. A simple pea or rice-sized dot of thermal paste applied to the center of the CPU is sufficient. Overdoing it may cause the paste to spill over the sides and compromise the connection points.
#7: Reassembling the CPU Heatsink
With the thermal paste in place, reattach the heat sink to the CPU. Ensure it sits evenly on the paste. Secure the heat sink back onto the CPU by tightening it in place. Replace the fan and plug it back into the motherboard.
#8: Final Steps
Take a moment to ensure everything has been put back to its original place before covering the case. Reconnect the power cord and peripherals and turn your computer on. Monitor the CPU temperature using software like HWMonitor, SpeedFan, or Core Temp to make sure the CPU overheats no more. If everything is working properly, congratulations! You’ve successfully replaced the thermal paste on your age-old CPU.
In conclusion, adequately applying thermal paste to your CPU enhances heat conductivity, thereby promoting optimal performance and longevity of your system. While it may seem a challenging chore, with sufficient caution and the right tools, you can easily carry out this task at home. As such, upgrading your aged CPU’s thermal paste is an inexpensive yet valuable preventive measure that should not be overlooked.
However, when working with computer components, remember these parts are delicate, and even slight mishandling can cause irreversible damage. Therefore, if you’re not confident in your abilities, it’s always best to call in a professional. Otherwise, with this guide in hand, you are well on your way to a cooler, more efficient CPU.
