This doubles the static pressure on your radiator compared to a single set of fans, resulting in superior cooling capacity.

In the sections below, we’ll provide details on optimal fan and radiator selection, installation best practices, push vs pull vs push pull, fan and pump orientation, controlling fan speeds, and much more. We’ll also analyze the pros and cons of this setup and help you avoid common mistakes.

Let’s take a deep dive into planning the ideal push pull radiator configuration!

Choosing Compatible Fans and Radiators

Radiator size and thickness

When it comes to choosing a radiator for your push pull setup, it’s important to consider the size and thickness of the radiator. The size of the radiator will determine how much surface area is available for heat dissipation, while the thickness will affect the overall performance of the cooling system.

A thicker radiator will typically have more cooling capacity, but it may also require more powerful fans to push air through it. On the other hand, a thinner radiator may be more suitable for systems with limited space, but it may not provide the same level of cooling performance.

It’s important to find the right balance between size and thickness based on your specific cooling needs.

High static pressure fans

High static pressure fans are an essential component of a push pull radiator setup. These fans are designed to overcome the resistance caused by the radiator and push air through it effectively. Unlike standard case fans, high static pressure fans are optimized for radiator cooling, providing a concentrated airflow to maximize heat dissipation.

When selecting high static pressure fans, look for models with a high CFM (cubic feet per minute) rating and a low noise level. This combination will ensure efficient cooling performance without excessive noise that could disrupt your gaming or work environment.

Matching fan and radiator specs

For optimal performance, it’s crucial to match the specifications of your fans and radiators. This includes considering factors such as fan size, airflow, static pressure, and noise levels. By choosing fans and radiators that are compatible with each other, you can ensure efficient heat dissipation and maintain a balanced cooling system.

It’s also worth noting that some radiator manufacturers may provide recommendations for specific fan models that work best with their radiators. Checking these recommendations can be a great starting point when selecting compatible fans for your push pull setup.

Ultimately, the compatibility between fans and radiators is key to achieving efficient cooling in a push pull setup. By considering factors such as radiator size and thickness, choosing high static pressure fans, and matching fan and radiator specs, you can create an optimal cooling configuration that keeps your system running smoothly and efficiently.

Installation and Configuration Steps

Radiator positioning in the case

When setting up a push-pull radiator configuration, it is crucial to consider the placement of the radiator within your computer case. Ideally, you want to position it at the front or top of the case, where there is ample airflow.

This ensures efficient cooling of the liquid passing through the radiator.

Additionally, make sure that there is enough space between the radiator and other components, such as the motherboard or GPU. This allows for better airflow and prevents any potential interference.

Fan mounting and alignment

Mounting the fans correctly is essential to maximize the effectiveness of your push-pull setup. Start by attaching the fans to the radiator using the appropriate screws or brackets. Ensure they are securely fastened and aligned properly.

It’s important to note that the push fans should be mounted on one side of the radiator, while the pull fans should be mounted on the other side. This setup creates a continuous flow of air through the radiator, maximizing cooling efficiency.

Wiring and powering fans properly

Proper wiring and power supply are crucial to ensure that your fans function correctly. Start by connecting the fans to the appropriate fan headers on your motherboard or fan controller. Make sure to follow the manufacturer’s instructions for proper wiring.

It’s also important to ensure that your power supply can handle the power requirements of the fans. Check the specifications of your power supply and compare them to the power consumption of your fans. If necessary, consider upgrading your power supply to ensure stable and reliable operation.

Setting custom fan curves

Configuring custom fan curves allows you to optimize the cooling performance of your push-pull radiator setup. Most motherboards and fan controllers offer software or BIOS settings to adjust fan speeds based on temperature.

To set custom fan curves, monitor the temperatures of your CPU and GPU under different loads and adjust the fan speeds accordingly. Aim for a balance between cooling performance and noise levels. Remember, a higher fan speed doesn’t always mean better cooling, as it can also result in increased noise levels.

For more detailed instructions on setting up custom fan curves, refer to your motherboard or fan controller manufacturer’s documentation. They often provide step-by-step guides on how to configure fan curves for optimal performance.

Remember, proper installation and configuration of your push-pull radiator setup are essential for efficient cooling and overall system performance. By following these steps and considering the best practices, you can ensure that your system stays cool even under heavy loads.

Optimizing Airflow with Fan and Pump Orientation

When it comes to setting up and configuring a push-pull radiator setup, optimizing airflow is crucial for effective cooling performance. Proper fan and pump orientation can make a significant difference in keeping your system running efficiently and maintaining optimal temperatures.

Let’s take a closer look at the different aspects of optimizing airflow in a push-pull radiator configuration.

Push Fan Direction

In a push configuration, the fans are mounted on the front side of the radiator, pushing air through the fins. The direction of the airflow is crucial to ensure efficient cooling. It is recommended to set the fans to push air towards the radiator, so that the air flows through the fins and dissipates heat effectively.

This setup helps maintain lower temperatures by forcing fresh air from outside the case into the radiator.

Pull Fan Direction

In a pull configuration, the fans are mounted on the back side of the radiator, pulling air through the fins. The direction of the airflow is just as important in this setup. The fans should be set to pull air from the radiator, allowing the heated air to be expelled out of the case.

This configuration is suitable when the case has limited space between the radiator and other components, as it helps prevent hot air from recirculating within the system.

AIO Pump Orientation

In addition to fan orientation, the pump orientation in an All-in-One (AIO) liquid cooler setup also plays a crucial role in optimizing airflow. The pump is responsible for circulating the coolant through the system and removing heat from the CPU.

It is recommended to position the pump in a way that allows for efficient coolant flow and minimizes any air bubbles that may form.

Most AIO coolers have the pump integrated into the CPU block, which is typically mounted on top of the CPU. The orientation of the CPU block and the pump should be such that the coolant flows smoothly without any obstruction.

It is important to consult the manufacturer’s instructions or guidelines for the specific AIO cooler being used to ensure the correct pump orientation.

Balancing Performance vs Noise

When setting up and configuring a push-pull radiator system, one crucial aspect to consider is finding the right balance between performance and noise. While you want your system to operate efficiently and keep your components cool, you also don’t want to be disturbed by the constant whirring of fans.

Here are a few tips to help you strike the perfect balance:

Choosing quieter fans

The type of fans you choose for your push-pull radiator setup can significantly impact the noise level of your system. Look for fans specifically designed for quiet performance, such as those with low decibel ratings or features like rubberized mounting points to reduce vibrations.

Brands like Noctua and be quiet! are well-known for their silent fans that deliver excellent cooling performance without sacrificing noise levels.

Lowering fan speeds

An effective way to reduce noise levels without compromising too much on performance is to lower the fan speeds. Most modern motherboards come with fan control options, allowing you to adjust the fan speeds based on temperature thresholds.

By finding the sweet spot where your components remain adequately cooled while running the fans at lower speeds, you can achieve a significant reduction in noise levels.

Sound dampening materials

Another approach to minimizing noise in your push-pull radiator setup is to use sound dampening materials. These materials can be applied to the interior of your computer case to absorb noise and vibrations, resulting in a quieter overall system.

Acoustic foam, rubber grommets, and anti-vibration mounts are some examples of sound dampening materials that can be used effectively.

Remember that striking the right balance between performance and noise is a personal preference. Some users might prioritize absolute silence, while others may prioritize maximum cooling performance. Experiment with different fan configurations, fan speeds, and sound dampening techniques to find the setup that best suits your needs.

What About Pairs vs Triples vs Quads?

When it comes to setting up a push-pull radiator configuration, one of the important considerations is the number of fans to use. You may have come across terms like pairs, triples, and quads in relation to fan setups, but what do they actually mean and how do they impact your cooling performance?

Let’s dive into it.

What two fans can achieve

A pair of fans in a push-pull configuration can already provide significant cooling benefits. In this setup, one fan is positioned to push air through the radiator, while the other fan pulls the air out.

This creates a continuous flow of air, maximizing heat dissipation and improving overall cooling efficiency. The two fans working together can greatly enhance your system’s cooling capabilities.

Benefits and drawbacks of adding more fans

Adding more fans to your radiator setup can further enhance cooling performance. With three fans, known as a triple setup, you can achieve even better airflow and cooling efficiency. The additional fan increases the pressure and volume of air being pushed through the radiator, resulting in lower temperatures for your components.

However, it’s important to consider the potential drawbacks as well. As you add more fans, you may experience diminishing returns in terms of cooling performance. This means that the additional benefits may not be as significant compared to the initial improvement from two to three fans.

Additionally, more fans also mean more noise, as the sound generated by the fans can stack up.

When to consider dual vs triple vs quad push pull

The decision of whether to opt for a dual, triple, or quad push-pull setup depends on several factors, including the level of cooling performance you require and the available space in your case. If you have ample space and need maximum cooling potential, a quad push-pull configuration might be worth considering.

However, keep in mind that this setup may require a larger case and can generate more noise.

On the other hand, if you have space constraints or don’t require extreme cooling power, a dual or triple push-pull setup can still provide excellent cooling performance while being more manageable in terms of noise and space requirements.

Ultimately, the choice between pairs, triples, or quads comes down to personal preference and the specific needs of your system. Experimenting with different fan configurations can help you find the right balance between cooling performance, noise levels, and available space.


Configuring a push pull radiator setup requires carefully selecting compatible components, proper installation, and optimizing airflow direction. With the right fans and radiator, mounting, wiring, and orientation, a push pull configuration can significantly lower temperatures compared to a single set of static pressure fans.

While more complex, push pull can maximize the potential of your liquid cooling system. We’ve covered all the essential details you’ll need to plan out an effective push pull setup. Just remember to choose high static pressure fans, align them properly, and balance performance with noise.

Your PC will benefit from the superior cooling capabilities of a push pull radiator configuration.
