Hey there, tech enthusiasts! As a supplier of Intel CPU liquid coolers, I often get asked about how to refill the coolant in these coolers. Today, I'm gonna walk you through the whole process step by step.
First off, let's talk about why you might need to refill the coolant. Over time, the coolant in your Intel CPU liquid cooler can evaporate or leak, which can reduce its cooling efficiency. When you notice that your CPU is running hotter than usual, or you hear strange noises coming from the cooler, it might be time to refill the coolant.
Before you start, make sure you have all the necessary tools and materials. You'll need a syringe, the appropriate coolant for your Intel CPU liquid cooler, a clean cloth, and some gloves. It's also a good idea to have a small container to catch any spills.
Step 1: Power Down and Unplug Your Computer
The first thing you need to do is turn off your computer and unplug it from the power source. This is crucial for your safety and to prevent any damage to your computer components. Make sure to also remove any external devices connected to your computer.
Step 2: Locate the Coolant Reservoir
The coolant reservoir is where the coolant is stored in your Intel CPU liquid cooler. It's usually a small, transparent container located near the radiator. In some models, it might be integrated with the pump. Check your cooler's manual if you're having trouble finding it.
Step 3: Prepare the Coolant
Get your coolant ready. Make sure it's the right type for your Intel CPU liquid cooler. Using the wrong coolant can damage your cooler and your CPU. If you're not sure which coolant to use, you can check the manufacturer's website or contact their customer support.
Step 4: Remove the Reservoir Cap
Carefully remove the cap from the coolant reservoir. Some caps might be sealed with a rubber gasket, so you might need to use a little force to remove it. Be gentle to avoid spilling any coolant.


Step 5: Refill the Coolant
Take your syringe and draw in the appropriate amount of coolant. Slowly inject the coolant into the reservoir, making sure not to overfill it. Most coolers have a maximum fill line indicated on the reservoir. Stop filling when you reach this line.
Step 6: Check for Air Bubbles
After refilling the coolant, gently tap the reservoir to release any air bubbles. Air bubbles can reduce the cooling efficiency of your cooler. Make sure to also check the hoses for any air pockets.
Step 7: Replace the Reservoir Cap
Once you're satisfied that there are no air bubbles, carefully replace the reservoir cap. Make sure it's tightly sealed to prevent any leaks.
Step 8: Clean Up
Use a clean cloth to wipe away any spilled coolant. Coolant can be corrosive, so it's important to clean it up immediately. Also, make sure to dispose of any used materials properly.
Step 9: Power On Your Computer
Now that you've refilled the coolant, it's time to power on your computer. Monitor your CPU temperature to make sure the cooler is working properly. If you notice any issues, such as overheating or strange noises, turn off your computer immediately and check for leaks or other problems.
Tips and Tricks
- Use Distilled Water: If you can't find the exact coolant for your Intel CPU liquid cooler, you can use distilled water as a temporary solution. However, make sure to add a coolant additive to prevent corrosion and algae growth.
- Keep Your Cooler Clean: Regularly clean your cooler to prevent dust and debris from clogging the radiator and hoses. This can improve the cooling efficiency of your cooler.
- Check for Leaks Regularly: Inspect your cooler for leaks periodically. If you notice any leaks, stop using your computer immediately and replace the faulty parts.
