- In the BIOS, check the CPU temperature to ensure it’s within the normal operating range.
How To Install A CPU Liquid Cooler?
Liquid coolers, also known as AIO coolers (short for All-in-One coolers), offer superior cooling performance compared to air coolers. They achieve this by using a closed-loop liquid circulation system that draws heat away from the CPU and dissipates it through a radiator mounted within the case. While the installation process is slightly more involved than with air coolers, it’s still manageable with careful planning and these step-by-step instructions:
1. Prepare Your Workspace
As with air cooler installation, find a clean, well-lit workspace with ample space to work on your PC. Remember to:
- Ground yourself to prevent electrostatic discharge (ESD) by touching a metal part of your case or wearing an anti-static wristband.
- Power down your computer completely and unplug it from the power source.
- Remove the side panel of your case to access the motherboard and internal components.
2. Assess Radiator Compatibility
Before starting the installation, ensure your liquid cooler’s radiator fits in your case. Most AIO coolers come in standard sizes like 120mm, 240mm, and 360mm. These sizes refer to the radiator’s length.
- Consult your case manual or manufacturer’s website to determine the supported radiator sizes for your specific case.
- Consider factors like airflow and clearance for other components when choosing a radiator placement. It’s generally recommended to mount the radiator as an intake (pulling cool air in) at the front of the case or as an exhaust (pushing hot air out) at the top.
3. Prepare The Motherboard
- Locate the CPU socket on your motherboard. Similar to air cooler installation, identify the mounting holes surrounding the socket that will be used to secure the CPU cooler pump block.
4. Install The Backplate (For Intel motherboards)
Similar to air cooler installation for Intel motherboards, you might need to install a backplate behind the motherboard.

- If required, follow the cooler’s instructions to install the backplate using the provided nuts or screws.
5. Attach The Mounting Brackets
- Identify the correct mounting brackets for your specific CPU socket type (e.g., AM4 for AMD or LGA 1700 for Intel) from the ones included with your AIO cooler.
- Align the mounting brackets with the corresponding holes around the CPU socket on your motherboard.
- Secure the mounting brackets using the provided screws or thumbscrews according to your cooler’s instructions.
6. Apply Thermal Paste (Optional)
- Most AIO coolers come with pre-applied thermal paste on the contact surface of the pump block. Double-check the manufacturer’s instructions. If there’s no pre-applied thermal paste, you’ll need to apply it yourself following the same steps as with air cooler installation (pea-sized amount in the center of the CPU’s IHS).
7. Mount The CPU Pump Block
- Carefully align the pump block of your AIO cooler with the mounting brackets on the motherboard.
- The pump block will typically have pre-attached screws or thumbscrews that thread through the brackets and secure it to the CPU.
- Tighten the screws or thumbscrews evenly in a diagonal pattern to ensure proper mounting pressure. Avoid overtightening as it can damage the CPU or motherboard.
8. Radiator Placement And Fan Installation
- With the pump block secured, it’s time to position the radiator within your case.
- As mentioned earlier, consider factors like radiator size compatibility, airflow, and clearance for other components when choosing the mounting location.
- Most cases have designated radiator mounting points, typically at the front or top. These locations will have pre-drilled holes for screws.
- Carefully position the radiator in your chosen location, ensuring the tubing from the pump block reaches comfortably without being excessively stretched or kinked.
- Secure the radiator using the provided screws according to your case’s mounting points.
- Once the radiator is secured, install the radiator fans (typically included with the AIO cooler) onto the radiator. Most radiators have pre-drilled holes for fan mounting. Follow the cooler’s instructions for proper fan orientation (ensuring airflow pulls cool air in or pushes hot air out).
9. Cable Management
Liquid coolers involve more cables compared to air coolers:
- Pump Power Cable: This cable typically connects to a CPU_FAN header or a dedicated AIO pump header on your motherboard. Consult your motherboard manual to identify the appropriate header location.
- Fan Cables: The radiator fans will have their own fan cables that typically connect to chassis fan headers on your motherboard. These headers might be labeled as SYS_FAN or CHA_FAN. Again, refer to your motherboard manual for specific header locations and fan connection options (some allow for PWM control for variable fan speed).
- Optional RGB Cables (if applicable): Some AIO coolers feature RGB lighting on the pump block or fans. These will have dedicated cables that connect to a compatible RGB header on your motherboard (typically labeled as RGB_HEADER or JRGB).
Carefully route these cables through your case, utilizing cable tie points or zip ties (optional) to manage them neatly. This will improve airflow within your case and create a cleaner aesthetic.
10. Double-Check And Power On
- Double-Check All Connections: Ensure the pump block is securely mounted, the radiator is firmly positioned, and all cables are properly connected to their respective headers on the motherboard.

- Enter BIOS settings: Typically accessed by pressing a specific key during boot (e.g., Delete or F2). Check the CPU temperature to ensure it’s within the normal operating range. You can also check the fan speeds to verify proper functionality.
FAQs:
You usually don’t need to change your CPU cooler unless it breaks or gets very noisy. The main thing to watch is the thermal paste, which dries out over time and affects cooling. It’s a good idea to replace the thermal paste every few years (4-8) or when you remove the cooler. As for the cooler, check your CPU temperatures regularly. If they’re normal and the fan isn’t making noise, everything’s fine! Just remember to clean out dust buildup occasionally to keep performance at its best.
Installing a CPU cooler upside down usually won’t cause damage, but it may not connect properly due to its specific mounting mechanism. Tower coolers with symmetrical fans might fit upside down, but this could reverse airflow and reduce cooling efficiency. It’s advisable to check your cooler’s manual for correct installation orientation.
CPUs produce a lot of heat, and thermal paste helps transfer this heat from the CPU to the heatsink. Without thermal paste, the heat isn’t effectively moved away, leading to high temperatures. This can cause performance issues, random shutdowns, or even permanent CPU damage. Thermal paste is essential to keep your CPU cool and your computer running smoothly.
Monitor your CPU cooler performance by checking the temperature and fan speed. Use software or BIOS/UEFI; tools like HWMonitor or Core Temp work well. Keep CPU temperatures within the safe range (50-80°C under load). High temperatures suggest poor cooling. Ensure fans increase speed only when necessary; constant high RPMs may indicate dust or a failing fan.
CPU coolers with RGB lighting are popular for building visually appealing PCs. These coolers have fans with RGB LEDs displaying various colors and patterns, often customizable via software. However, RGB lighting can increase the cooler’s cost. If aesthetics aren’t a priority, high-performing coolers without RGB might offer better value.
