**Comparing Open-Air and Blower-Style Graphics Cards**
The SG 13 case with decent ventilation proved to be an excellent choice for our RT X 2070 Super card, providing the best GPU thermals out of the four cases tested. The blower card allowed our Rison processor to run around five and a half degrees cooler, which is a significant advantage in this setup. However, we noticed that the CPU temperature was about eight and a half degrees warmer with the open-air card configuration.
In contrast, the blower-style graphics cards showed promising thermal designs, but they fell short in terms of cooling performance when compared to our open-air card. The GPU clock speeds were only about 40 megahertz faster than the Isuzu turbo blower card, which may not be noticeable in most games. Additionally, the CPU thermals with the open-air card were significantly warmer, indicating that the hot air from the graphics card was affecting the CPU temperature.
The Sentry 2.0 case presented an interesting thermal design challenge due to its slim console lock form factor. The graphics card was connected via a two-piece riser card that stacked it above the motherboard and power supply. This setup allowed for ample ventilation at the top, but the heat also directed towards the motherboard, trapping some of it inside the case. As a result, we saw more thermal differences between the open-air and blower-style graphics cards in this configuration.
**Performance Comparison**
In our tests, the GPU thermals were fairly close between the two configurations, with only about one to two degree difference. However, for CPU temperatures, we saw an eight and a half-degree warmer result with the blower card. This significant difference highlights the importance of proper cooling design for both GPUs and CPUs in compact cases.
The noise levels also played a crucial role in our comparison. The blower-style graphics cards created a louder system due to their fans, which was still audible even at 30 minutes of continuous operation. However, if we were to run a fan curve instead, the two configurations might become closer in terms of noise levels.
**Recommendations**
For users building small form-factor cases or gaming rigs with limited volume, we highly recommend an open-air graphics card for its more effective cooling design and lower temperatures. While the thermal design of blower-style cards is promising, they often rely on cheaper components to achieve their performance claims. In certain situations, such as slim console-like cases or scenarios where CPU thermals are critical, blower cards can be beneficial.
However, when building in a small space, we recommend opting for the largest graphics card that will fit inside the case. This usually provides the best performance and cooling solution. Additionally, users should keep an eye on CPU cooler thermal increases relative to what they'll get with a blower card. A more premium cooling solution often means better overall system temperatures.
**Conclusion**
In conclusion, our tests demonstrated the importance of proper cooling design in compact cases. While both open-air and blower-style graphics cards have their strengths and weaknesses, we recommend an open-air card for most users due to its more effective cooling solution and lower temperatures. However, users should consider their specific needs and case constraints when making a decision.
**Recommendations for Open-Air Graphics Cards**
For those looking to build in small form-factor cases, we recommend the following:
* Check out our recommended list of top open-air graphics cards.
* Consider the largest graphics card that will fit inside your case.
* Keep an eye on CPU cooler thermal increases relative to what you'll get with a blower card.
* Don't be afraid to consider manual tuning or under-volting to optimize performance.
**Recommendations for Blower-Style Graphics Cards**
For users who may benefit from the benefits of blower-style graphics cards, we recommend:
* Consider the advantages of blower-style graphics cards in slim console-like cases or scenarios where CPU thermals are critical.
* Look for high-quality blower-style graphics card designs that prioritize thermal performance and noise reduction.
* Be aware that blower-style graphics cards often rely on cheaper components to achieve their performance claims.
**Final Thoughts**
In the world of compact gaming PCs, cooling design is everything. While both open-air and blower-style graphics cards have their strengths and weaknesses, we recommend an open-air card for most users due to its more effective cooling solution and lower temperatures. By considering your specific needs and case constraints, you can make an informed decision that ensures optimal performance and thermal comfort in your gaming rig.
