Can you replace the GPU cooler

It's that easy to put together your custom water cooling

There are some water cooling systems on the market that deliver an all-round carefree package, so to speak, but these do not always fit into the existing systems. An individual solution can make sense if you have installed very special components, prefer an unusual arrangement or just want a little more leeway. So if you want to start the project to install your custom water cooling, you need it first four basic components: the cooler, the pump, the radiator and suitable hoses. We'll tell you now what to look out for when choosing one of these.

The cooler

At the beginning of the process you have to decide what parts of your pc you want to provide the cooling. Because ultimately the choice of your cooler also depends on it. While you can actually connect any component - i.e. motherboard as well as power supply unit, RAM, CPU and GPU - custom water cooling is particularly worthwhile for the processor and graphics card. Because these usually work the most - especially if you use your PC for gaming - and are therefore most likely to overheat or wear out. We therefore want to focus on these two types as well.

The CPU cooler

They are the easiest option when choosing, because you don't have to pay too much attention to the CPU cooler. Above all, it is important that you know the manufacturer and which one Socket the processor installed. Then nothing can actually go wrong.

If you have these facts ready, it is about the selection of the cooling capacity. This depends on the Number of built-in cooling fins. In general, the more fins, the larger the surface and the more heat can be transferred from the CPU to the water.

However, the finer structure also means that the liquid encounters more resistance, which in turn means that it cannot flow through as quickly. The heat is therefore removed more slowly. Make sure that you connect a pump that compensates for this resistance as effectively as possible.

The GPU cooler

If you want to (also) connect your graphics card to the custom water cooling, this is usually one more complicated undertaking, since not every GPU is readily compatible with this system. Many Grakas even come with pre-installed fans. You can find online lists for your existing card that show whether it is made for water cooling or not. If, on the other hand, you are only buying a new model, it is best to ask whether such a cooling variant is possible before making the final decision.

If you can connect your graphics card, we would also always give you a so-called one Full cover water cooling guess. This means that a relatively large cooler is attached to the card. This means that the water can not only flow around the graphics chip, but also the memory blocks and the power supply. All of these components are ultimately responsible for the heat generated by the card. For efficient cooling, it makes sense to "intercept" the heat at the possible exit points.

The pump

So that the water removes the excess Also effectively transporting away heat it needs a pump that moves it. Here you have the choice between very different sizes. These can be individually adapted to your requirements. Basically, however, you can assume that the models with a higher filling volume bring less pressure, but are overall quieter than the smaller pumps.

You also need an expansion tank to fill your custom water cooling system. This is the place where excess air is collected. In addition, it can ensure pressure equalization if this is required. In general, there are models where Pump and expansion tank were installed together. But you can also attach them separately in the housing.

The radiator

The radiator is essential for efficient custom water cooling, because it is responsible for the fact that the absorbed heat is released into the environment. First you have to choose between internal and external heat exchangers decide.

The internal radiator

As the name suggests, the internal radiator is located inside the computer case. With that he is very limited in its construction, because the space as well as the potential positions are limited. Conversely, this means that only a limited number of fans can be used to cool the water. Therefore, only heat exchangers with two or three fans are commercially available.

However, an internal radiator always brings with it similar problems as the conventional fan system. The excess heat remains in the housing and can only partially be released into the environment. That's why it is planning Definitely the be-all and end-all here.

Above all, make sure that you get one if possible great distance between the most powerful components (mostly graphics card and processor) and the radiator. In addition, the radiator should always be installed close to the case fan itself, so that the maximum volume of heated air is immediately discharged outside and heat build-up is prevented.

The external radiator

You are better positioned with an external radiator. This one will about hoses connected to the cooler on the GPU or CPU and immediately dissipates the generated heat to the environment. He has constant access to fresh air and is therefore particularly efficient. The inside of the case, on the other hand, barely heats up. You are also not restricted in terms of size (and thus the required performance).

The hoses

In order to connect the individual components with one another and to put the system into operation, you still need the right hoses. Here you should first pay attention to the size of your connections for the pump, radiator and cooler. Because safe transport of the liquid can only be guaranteed if these correspond to the diameter of the tubes. In addition, we strongly advise you to do so, too Sealing rings use - these will help you prevent unwanted leaks.

The Standard hose measures 1/4 ″ by the way. The first number indicates the inner diameter in inches, while the second indicates the outer diameter. In Europe, however, the 13/10 hose (i.e. 13 mm outer, 10 mm inner diameter) is widely used.

Once you have found the right diameter, you have to choose the hose yourself. Most systems use flexible variants. Above all, these have the advantage that they can be easily adapted individually and actually fit into any environment. If, on the other hand, you have fun tinkering, you can too stareTube be an attractive alternative. But be sure to make a plan beforehand and adjust the sizes accordingly.
