Laptops that don't have adequate cooling can run hot enough to damage the processor, but most laptops will shut the system down to prevent the processor from being permanently damaged. The cause is frequently a combination of heat generated by the processor, hard drive and memory. High-performance laptops that aren't frequently transported can benefit greatly from a water-cooled system. A water-cooled system can be expensive. However, it's extremely quiet and will efficiently cool your laptop.

Unplug your laptop and remove the battery from the bottom of your laptop.
Remove the keyboard from the top of your laptop to expose your laptop's motherboard, processor, heatsink and cooling block. Remove the processor's heatsink and cooling block from the motherboard.
Screw the two metal pillars into the mounting holes for the processor, located on the motherboard. These pillars are provided in your water-cooling kit.
Remove the old thermal paste from the back of the processor, and reapply new thermal paste to the processor. Place the CPU waterblock onto the processor. Place the bracket onto the waterblock and screw it directly to the pillars.
Drill a hole in the side of the laptop where the hoses will exit the laptop to run to the reserator. The reserator is an external tower that serves as both a reservoir and a radiator that cools your laptop's CPU.
Measure the length from the reserator's outlet port to the CPU waterblock's inlet port, and the CPU waterblock's outlet port to the reserator's inlet port. Cut two pieces of tubing to the measured lengths. The tubing is supplied in the water cooling kit.
Unscrew the top of the reserator and pour in the coolant and distilled water.
Attach the compression fitting cap over each hose, and screw the cap over each hose until it is tight. Using the needle-nose pliers, fasten the reserator's couplings to the hose with tube clamps.
Turn on the reserator and check all of the hose connections for leaks. If any leaks appear, immediately stop the pump and tighten the fitting. If the cooling unit is drip-free after an hour, close-up your laptop.
Boot up your laptop and monitor the processor's temperature by rebooting into the BIOS.
Tips and warnings
- Use only distilled water in the tubing to prevent mineral build-up or algae growth.
- Static electricity can destroy your laptop. Touch metal or use an antistatic strap to remove static from your body before handling electronic parts.
- Using a water cooler on your laptop could cause irreparable damage if any water leaks out of the cooling system and into the laptop.
- Opening your laptop case and adding a water cooler will void your laptop warranty.
