The GPU (Graphics Processing Unit), VRAM (Video Memory), and VRM (Voltage Regulator Module) are the components of a graphics card that generate the most significant heat. Therefore, all of the features described above must be kept cool; otherwise, your computer’s graphics card may experience difficulties such as instability, shutdowns, freezing, or even damage.

Inside the graphics cards, there are generally two sorts of air coolers and fan types. One is a blower GPU, while the other is a fan GPU. These air conditioning devices perform the same function and have their own set of benefits and drawbacks. These pros and disadvantages may be essential to consider when purchasing a graphics card to meet your unique requirements.

Blower Vs Fan GPU | The Ultimate Comparison 

The distinction between GPU CPUs boils down to how the fans on your graphics card get rid of that excess heat. Both types employ one or more fans on the cooling unit, placed on the outside of the plastic case and powered by the card. These fans draw in the heated air from within your PC case. They don’t discharge air into it, at least not right away.

Check out the chart below for more information on the uses, benefits, and differences between the Blower vs. Fan GPU.

Blower Vs Fan GPU

Blower GPU

 A blower-style cooler is often seen in laptop CPUs, and it comes with a blower-style fan. This fan pulls air from the top and pushes it sideways to the heatsink fins, where it may quickly exit via the back. The hot air held in the graphics card escapes through the back vents, which also house the graphics card’s display connections or ports in blower coolers.

NVidia’s Founders Edition graphics cards are all equipped with blower-style cooling. These blowers are standard in low-cost graphics cards, particularly those made in China. On one end of the graphics card, you can see a blower-style cooler with a blower-type fan.

It is average, and the fan makes very little noise, but it can become extremely noisy at larger loads. In addition, overclocking is difficult for graphics cards with blower GPUs due to their poor cooling capabilities. However, compared to some of the massive open-air or fan coolers that may take more than two slots on your motherboard or computer case, these coolers are thinner and shorter in length. For obvious reasons, this is also known as a “rear exhaust” design. Here’s an example of what it looks like:

The Dark Point About The Blower GPU

The blower fans were said to be quite hot and noisy. However, intellectually understanding something and experiencing it are two very different things. When you think of a “gaming PC,” hot and noisy don’t even begin to characterize a blower fan.


These open-air GPU coolers, also known as Fan GPU coolers, use a conventional technique where a fan is placed above the heat sink and pushes cool air directly over it. Most of them employ fan coolers, whether it’s a cheap, mid-range, or high-end graphics card. In addition, these coolers are usually larger than blower-style coolers compared to graphics cards with the same GPU.

 May include Heat pipes in the heatsinks of these coolers for improved heat dissipation and transmission, but heat pipes are not included in the heatsinks of blower fan-type coolers.

 May overclock a graphics card with a decent open-air cooler or a fan cooler with two or triple fans to higher frequencies, which is impossible with blower coolers. Open Air Fan Coolers with numerous fans are included with all OC Edition Graphics Cards. For your convenience, I’ve included a photo of an open-air fan graphics card cooler with three fans and its airflow.

Performance Of A Fan GPU

Fan-type coolers outperform blower-type coolers in terms of performance and are also reasonably quiet when in use. An open-air cooler can have up to three fans, but a blower cooler can only have one fan, regardless of how powerful the graphics card is. May use small form factor graphics cards with open-air fan cooling in SFF or Mini-ITX systems.

Dark Point About The Fan GPU

Because most of the hot air from the cooler is distributed in all directions or gets spread in the computer case, it may increase case temperature. However, between the Blower VS Fan GPU, Fan having excellent airflow within your PC case and a sufficient number of case fans may quickly alleviate this problem. It should have at least one intake and one exhaust fan, according to our recommendations.

Which One Is Better Between The Blower And Fan GPU?

That is dependent on your configuration to decide between the Blower VS Fan GPU. Open-air coolers function better in a traditional desktop PC with a large, spacious chassis and a few case fans, cooling the GPU to a somewhat more prominent degree. It is because they have more excellent airflow and fewer obstacles. 

Having that extra flow will keep your GPU a little cooler, even though the system utilizes the warm air that’s already within the case. For most users, the differences between the two types of coolers GPU are insignificant—less than five degrees of heat in one direction or the other, which is generally insufficient to cause decreased performance.

Of course, high-end users who wish to control better their internal airflow (or build a cool-looking PC) may utilize a liquid cooling solution, which already uses a radiator to evacuate the air. If you don’t have any special requirements for your PC case’s ventilation, don’t worry about the blower vs. Fan GPU debate. 


It should be evident for you to choose between the Blower Vs. Fan GPU according to your system requirements. For example, if you’re creating a minor case or intend to use liquid cooling on your CPU, a blower GPU cooler is a way to choose if the cards are otherwise equivalent. On the other hand, select an open-air design if you intend on overclocking your GPU and need maximum performance in a big chassis.

Between the Blower vs. Fan GPU, were known The Blower fans for being extremely hot and noisy. However, intellectually understanding something and experiencing it are two very different things. When you think of a “gaming PC,” hot and noisy doesn’t even begin to explain a blower fan; to comprehend the realism of the experience, imagine an electric hand drier in a public toilet or a hairdryer.
