Can An Overheating Computer Be Cooled With Water?

Have you ever thought about using water to cool your overheating computer? Well someone else has thought about this a long time ago, and now water cooling for computers is a widespread practice.

Of course, this is very unnecessary unless the computer is used for high intensity purposes. On the commercial end, most water cooled computers are used for gaming. Whether or not gaming is something purposeful, there is no doubt that it stretches computers to the limit.

Many gamers have stated that their computers tend to freeze at that crucial moment in a game when they are about to kill an enemy with a headshot. Regardless of the use of your computer, water cooling can improve efficiency dramatically.

Can I Use Water To Cool My PC?

Please do not pour water on or into your computer just because it gets hot. Doing so will cause the internal components to short circuit, and then the system will get burnt out –maybe permanently.

Water-cooling is all about a simple concept that allows the transfer of heat through water. The water carries the heat away from the computer, thus keeping it cool. The water does not touch the computer directly.

There are water cooling systems available for purchase; but because the technology is so old and simple; it almost seems better (no doubt cheaper) to build it by oneself.

Building A Water Cooling System For Your Computer

Building a water cooling system for your computer will require a box to hold everything; that box could be made of wood or plastic; something like an old speaker box should do nicely.

You then need copper tubes; the type that is used for fridges. You also need some tubes; the types used in the hospitals and clinics to deliver medication intravenously.

You will need a jar of water, and a small aquarium pump to move the water around the circuitry.

You will also need something to take the water to the processor without the water touching it. That something is called a Direct Die Cooler. It sits on top of the processor while the water flows through it; thus facilitating the exchange of heat.

You will need a fan. The fan blows away the heat; which means even though it is water cooled, it is still air cooled.

How To Assemble The Water Cooler

The first thing to do is to prepare the frame to hold the arrangement of parts together. The front side of the containment has to be removed; that is where the copper tubes will pass through. The tubes can pass through small openings at the sides, or (more safely) it can be held by pegs which may then be screwed.

The copper tubes are to be passed horizontally. They should not touch each other, but should run parallel on top each other to form a kind of close knit zig zag formation. Those who are more handy can make the copper tubes pass through upright aluminum slats. This will increase the efficiency of the arrangement.

After passing the copper through the frame to look like a radiator or an AC unit; then cut off the copper at both ends; and then fix the rubber tubes.

One end of the rubber tube will go to the pump, while the other end will go to the water jar. From the water jar, another pipe will go to the Direct Die cooler which will be mounted on the processor.

The Direct Die cooler will have two openings, which is where the other tube coming from the other opening on the pump will be connected.

Next is to mount the fan. The above diagram is over simplified, but it shows that the fan should be mounted behind the radiator (which is your arrangement of copper tubes).

Then fill up the water container, and power it up.

Does Liquid Cooling Prevent Overheating?         

If the computer runs more efficiently, then yes it works. Things like this will not be appreciated until they are faulty. The need for a more efficient cooling system only arose because the computer was overheating. When it does not overheat, nobody gives it a second thought.

A hint as to the effectiveness of this cooling system can be provided by putting one’s hand in front of the radiator, and feeling the air coming out of it.

The hot air may take a while to form; this is what happens when the computer really works itself to the max thus producing heat. The hot air coming from the radiator is a sign that the cooling system works. Let us explain in detail how it works.

How A Computer Radiator Works

When computers work, they produce heat. The job of the water cooling system (the radiator) is to transfer that heat away from the computer. When the heat is efficiently carried away from the computer processor then the computer can continue to function optimally, carrying out whatever tasks it is supposed to do.

The heat transfer is done by absorbing the heat into the water, which is then transferred to the copper tubes which will transfer the heat into the air. Except it cannot do that on its own.

The fan blows fast moving air towards the copper tubes, thus taking the heat into the air, and cooling the tubes at the same time. As the copper tubes become cool, so does the water inside.

But the water does not stay still; through the action of the small pump, it flows back into the water jar, and back to the processor as cool water, keeping the processor cool, and working optimally.

So in fact, is it water cooled or air cooled?

The following are questions about Water Cooling Systems For Computers

Is Water Cooling PC Good Or Bad?

Short answer; it is good. But it is only good if it is necessary; that is if the computer is put to some serious use which produces heat.

After that, the individual circumstances of the user will still need to be considered, so as to determine whether it is a good idea to go with water cooling for your computer.

The following questions can help.

Is It Expensive?

Computer radiators are not expensive, and they are cheaper still to build by oneself.  Energy consumption is low; a single USB connection into the computer can provide all the power needed to operate a computer radiator.

However, the expenses may be considered high if the buyer has no real need for it. On the other hand, a person whose computer frequently freezes or goes off after exceeding the limit of its thermal capacity will gladly shell out a few bucks to purchase a radiator for his computer needs.

Is It Mobile?

No. this is something that should be mounted close to a desktop computer. Furthermore, a part of the cooler is connected on the processor, which is inside the computer.

Is It Quiet?

A radiator makes a whirling sound; which is a by product of the fan working. That sound will hardly be noticed when one is busy with something else, especially something with sound. However, it can be a minor nuisance on standby mode.

Further Reading:


Overheating computers can be a thing of the past with this simple water cooling system. In fact, water cooling is becoming more popular especially among the gaming community where computers are put to extreme use.

High powered servers also make use of radiators and various other types of cooling to keep the computer temperatures down while doing plenty of work.
