Do Blower-Style Graphics Cards Sacrifice Performance for Lower Temperatures?
For the uninitiated, a blower-style graphics card is a type of graphics card that uses a fan to blow air through the heat sink and cool the internals of the card. These types of cards are typically found in small form factor builds or in systems that require high airflow. They are also often used in server builds due to their ability to keep a consistent temperature in a closed environment.
But the question remains: do blower-style graphics cards sacrifice performance for lower temperatures? We’re going to explore that question in detail in this blog post.
Understanding Blower-Style Graphics Cards
To understand how blower-style graphics cards work, it’s important to know the basics of how traditional graphics cards function. A traditional graphics card features a large heatsink that sits on top of the GPU (graphics processing unit) and other components. This heatsink dissipates heat from the internals of the card and transfers the heat to the surrounding air. This type of graphics card design is known as an open-air design because the heatsink is exposed to the surrounding air.
Blower-style graphics cards, on the other hand, use a different design. Instead of a large heatsink, these graphics cards feature a smaller heatsink, with a fan attached to it. This fan pulls in air from the front of the card and exhausts it out the back, creating a more focused airflow that moves through the interior of the card. This type of graphics card design is known as a closed-air design because the heatsink is enclosed within the card.
Blower-Style Graphics Cards vs. Traditional Graphics Cards: Temperature Differences
The primary reason that blower-style graphics cards were introduced was to provide better cooling performance in cramped computer cases or cases with poor airflow. Compared to traditional graphics cards, blower-style graphics cards typically run at much lower temperatures. This is because the closed-air design of the heatsink and fan arrangement creates a focused airflow that moves across the components of the GPU more effectively than traditional passive cooling.
For example, a blower-style graphics card like the AMD Radeon RX 580 will often run at around 66°C under a heavy load, while a traditional graphics card like the NVIDIA GeForce GTX 1080 will run at around 75°C under the same conditions. This means that a blower-style graphics card will typically run cooler and will not overheat as quickly under heavy loads.
Blower-Style Graphics Cards vs. Traditional Graphics Cards: Noise Differences
Another major difference between blower-style graphics cards and traditional graphics cards is the level of noise that each type of card generates. Blower-style graphics cards run much more quietly than traditional graphics cards, because they move the same amount of air at a lower velocity. This makes them ideal for scenarios where noise is a concern, such as home theater PCs (HTPCs).
On the other hand, traditional graphics cards use a larger heatsink and multiple fans to cool the internals of the card. This allows them to run at higher speeds, but also means that they generate more noise. If you’re building a gaming PC that’s going to be used in a noisy environment, such as a LAN party, then a traditional graphics card is likely your best bet.
Blower-Style Graphics Cards vs. Traditional Graphics Cards: Performance Differences
So, now that we’ve talked about temperature and noise differences, let’s discuss performance. Do blower-style graphics cards sacrifice performance for lower temperatures? The answer is… it depends.
In general, blower-style graphics cards do not offer the same level of performance as traditional graphics cards, primarily because they are designed with a smaller heatsink and typically run at lower speeds. However, this is not always the case.
For example, the NVIDIA Titan Xp Collector’s Edition graphics card features a blower-style heatsink design, but it is still one of the most powerful graphics cards available today. This is because the card features a custom PCB design and a higher double-precision floating point performance rating.
Another factor to consider is the size of the computer case that you’re building in. If you’re building a small form factor PC and don’t have much room for a large heatsink, a blower-style graphics card may be your only option. In this case, sacrificing a few percentage points of performance may not be a big deal, since you’re building a system that’s designed to be quiet and cool.
Conclusion: Are Blower-Style Graphics Cards Worth It?
So, are blower-style graphics cards worth it? It depends on your priorities. If you value temperature and noise levels over pure performance, then a blower-style graphics card may be the right choice for you. On the other hand, if you want maximum performance and don’t care about noise levels, then a traditional graphics card is likely the better choice.
In general, blower-style graphics cards are great for small form factor systems or for use in server environments where consistent temperatures are essential. They are also an excellent option for people who are building a quiet HTPC and don’t want to hear loud fans all the time.
Ultimately, the choice between a blower-style graphics card and a traditional graphics card comes down to a matter of personal preference. Both types of cards have their advantages and disadvantages, so it’s important to consider your priorities before making a final decision.
