How much radiator for cpu and gpu?

There are a variety of factors to consider when deciding how much radiator you need for your CPU and GPU. The size of your case and the amount of airflow will play a role in how much radiator you need. You will also need to take into account the overclocking potential of your CPU and GPU. If you are planning on overclocking your components, you will need more radiator to keep them cool. Ultimately, the decision of how much radiator you need will come down to your specific build and how you plan on using your computer.

It really depends on what kind of CPU and GPU you have. If you have a higher end CPU and GPU, you might need a 240mm or 280mm radiator. However, if you have a lower end CPU and GPU, you might only need a 120mm or 140mm radiator.

Can 1 radiator cool a CPU and GPU?

If you want to use a 240mm radiator for your GPU and CPU, it’s probably best to get a pump, reservoir, and radiator that are designed for that purpose. Otherwise, you may not get great temperatures, and you’ll have to mess around with connectors and tubing anyway.

You can run a 360 and 240 with cpu/GPU blocks and a good pump without any issues. You might need to get a bit creative with the tubing, but it can be done!

Can a 240mm radiator cool CPU and GPU

The 240mm radiator is 27mm thin yes i know, it is push pull and located at the front and my temps on cpu and gpu after 2-3 hours of gaming or benching with a 27C – 29C ambient temperature, CPU reaches 75C and GPU reaches 70C.

AiO water cooling is a great way to keep your CPU cool, and a 120mm radiator is more than sufficient to cool a 100 watt CPU. However, if you plan on overclocking your CPU, or if you live in a warm climate, you may want to consider a larger radiator. A 240mm radiator will provide plenty of cooling power for an AMD Ryzen 7 5800X 3D, and will keep your CPU running at its best.

How hot is too hot for my CPU and GPU?

Anything under 60 degrees C (140 degrees F) is perfect. Just above this temperature is okay, but as you creep above 70 degrees C (158 degrees F), you should look at how to cool your PC down. Above 81 degrees C (178 degrees F) is too hot and could cause damage to your computer if you run it for a sustained period.

The ideal temperature range for a GPU is between 65 and 85 degrees Celsius. However, during intense rendering or gaming sessions, the temperature can rise to between 70 and 80 degrees Celsius. Once the temperature reaches this range, it is important to take a break and allow the GPU to cool down to avoid damaging it.

Should I get a 360mm or 240mm AIO?

A larger radiator will indeed dissipate heat more effectively than a smaller one, all else being equal. However, this also means that the fans will need to work harder to move the same amount of air, which can lead to more noise. You’ll need to decide what’s more important to you: a quieter system or one that runs cooler.

A single 360 mm radiator is usually enough to cool both a CPU and GPU loop. If you want to run the fans at a lower RPM for silent operation under load, you may need more rad space.

Is 360mm AIO overkill

There is no doubt that a liquid cooling solution will outperform air cooling, especially if you are looking to push your system to its limits. However, for a more casual user, a 240mm AIO (all-in-one) cooler should suffice. Even a 360mm cooler would be overkill.

If you’re looking to liquid-cool your PC for better performance, it’s important to choose the right radiators. The rule of thumb is to use at least one 120mm radiator (section) per each water cooled component plus one additional section. So, if you’re cooling a CPU and a single graphics card, you’ll need at least a 360mm (3x 120mm) radiator. Of course, more radiator surface area will provide better cooling, so keep that in mind when choosing your components. For the best results, consult a cooling expert to ensure you have the right setup for your needs.

Can a 280mm radiator cool a CPU and GPU?

A single 280mm radiator will not be able to cool a CPU and GPU properly unless high speed fans are used. Push/pull will not help much, it helps at low fan speeds (500-700 RPM) but the higher the fan speeds, the smaller the benefit of push/pull.

At the same fan speed (1800 RPM), a 240mm XE radiator can remove around 500W of heat when the liquid temperature is 15°C higher than the ambient temperature. This is because a higher liquid temperature means that the radiator becomes more efficient and can remove more heat.

Is 48c too hot for CPU

If you have an Intel or AMD processor, you could say that a CPU core temperature of over 45-degrees Celsius while idling and/or a temperature of over 95-degrees Celsius while under full load is probably a cause for concern.

The size of your fan can have an impact on the overall performance of your computer. If you have a larger fan, it will be able to move more air and keep your components cooler. However, this also means that the fan will be louder. If you are looking for the best performance, a larger fan is the way to go. However, if you are concerned about noise, you may want to stick with a smaller fan.

Do bigger radiators cool better PC?

The size of the heatsink is important for performance, but it is not the only factor. The number of heat pipes and fans also play a role in how well the heatsink performs. The more heat pipes, the better the heat transfer to the heatsink. The more fans, the more airflow. The more airflow the fans can push, the better the performance.

The CPU temperature while gaming should be kept at 75 to 80 Celsius in order to avoid overheating and damaging the computer. The optimal CPU temperature should not exceed 80 Celsius in order to maintain the best performance while gaming.


There is no definitive answer to this question as it depends on a number of factors, including the specific CPU and GPU models in question, the workload, the environment, and other factors. However, a good rule of thumb is to have at least 1 radiator for the CPU and 1 radiator for the GPU, with 2 or more being even better.

The amount of radiator needed for a CPU and GPU depends on the specific models and how much heat they generate. Generally, it is recommended to have at least two 120mm radiators for a CPU and GPU setup.
