When it comes to graphics processing units (GPUs), one of the most common questions is whether the fan should be set to intake or exhaust. The answer to this question depends on a few factors, including the type of GPU and the case. In general, however, GPUs with reference coolers should have the fan set to intake so that hot air is pulled away from the components.
Are GPU Fans Intake Or Exhaust
If you’ve ever wondered which way your GPU fans should be facing, the answer is simple: intake. That’s because GPUs tend to produce a lot of heat, and having the fans suck in cool air from outside will help keep things running smoothly.
Of course, there are always exceptions to the rule. If you have a particularly powerful GPU that produces even more heat than usual, you may want to consider setting up an exhaust system so that hot air can be pulled out of your case. But for most people, intake is the way to go.

Which Way Do GPU Fans Exhaust?
Assuming you are referring to computer GPU (graphics processing unit) fans, they typically exhaust the hot air out the back of the case. This is because most GPUs are mounted vertically on the motherboard with the fan(s) facing towards the back panel of the case. By exhausting hot air out the back, it gets pulled through the heatsink and cooling fins on the GPU which helps keep things cool.
Some higher end GPUs or those with more robust cooling solutions may have two fans that intake cool air from inside the case and exhaust it out the back.
How Does a GPU Exhaust Air?
The exhaust of a GPU is important for cooling the device and preventing overheating. The fan inside the GPU draws in air from outside the case and forces it through the fins on the heat sink. The hot air is then exhausted out of the back of the case.
If there is not enough airflow, the GPU will overheat and may be damaged.
Is CPU Fan Intake Or Exhaust?
Assuming you are talking about a standard computer CPU fan, the answer is that it is an intake fan. That means that it takes in air from the outside and blows it across the CPU to help keep it cool. Some cases have a separate exhaust fan that helps push the hot air out of the case, but not all cases do.
So, if your case only has one fan, and it’s blowing air into the case, then that’s your CPU fan and it’s an intake fan.
Are PSU Fans Intake Or Exhaust?
Most power supply units will have their fan facing the front of the case as an intake. However, depending on the layout of your case and other components, it’s not uncommon for the PSU to be mounted upside down with the fan facing downwards as an exhaust. There isn’t a “correct” way to orient your PSU, but we typically recommend having the fan face towards an intake so that it can draw in cool air from outside of the case.

Are CPU Fans Intake Or Exhaust
As you might have guessed, the answer to this question is a bit more complicated than a simple yes or no. In most cases, CPU fans are designed to be used as either intake or exhaust fans, depending on the needs of your particular setup.
If you have a standard tower case, the vast majority of airflow will come from the front panel intake fan(s).
This brings cool air in from outside of the case and forces it through the various components inside, including the CPU cooler. The hot air is then exhausted out the back and top of the case by one or more fans.
In some situations, however, it may be beneficial to reverse this airflow pattern.
For example, if your CPU cooler is particularly large or has a lot of fins/heatpipes sticking up into the path of incoming airflow, it can block a significant amount of that airflow from reaching other parts of the motherboard and GPU. In this scenario, it would often be preferable to use the CPU fan(s) as exhaust fans instead. This would pull hot air directly off those components and expel it out of the case quickly and efficiently.
There are also instances where using both intake and exhaust fans on the same side of the case can create positive pressure inside- meaning there’s slightly more air being brought in than expelled. This can help reduce dust buildup inside your case over time as well since there’s less opportunity for particulates to find their way in through gaps and cracks. Positive pressure setups typically use larger intake fans than exhaust fans though, so it’s important not to go overboard or you’ll just end up with noisy Fans spinning away for no reason!
Conclusion
GPU fans are designed to be intake fans. This is because they are responsible for cooling the GPU, which generates a lot of heat. The intake fan draws cool air from outside the case and into the case, where it can cool the GPU.
