We found previously that stacking multiple RTX 2080 video cards next to each other for multi-GPU rendering led to overheating and significant performance throttling, due to the dual-fan cooler NVIDIA has adopted as the standard on this generation of Founders Edition cards. Now that manufacturers like Asus are putting out single-fan, blower-style cards we can repeat our testing to see if the throttling issues are resolved and find out how well these video cards scale when using 1, 2, 3, or even 4 of them for GPU-based rendering in OctaneRender and Redshift.
The new GeForce RTX series cards perform well in GPU based rendering, as individual cards, and have great potential for the future thanks to their new RT cores. However, when stacking them together to measure multi-GPU scaling we ran into some serious problems.
Puget Systems has used many variations of the Antec TriCool 120mm fan over the years – including the red, blue and green LED versions in our colored case fan kits – due to their excellent noise to airflow ratio. However, Antec has recently discontinued the green LED version of the Antec Tricool, so we needed to find a good replacement fan for our green LED kits. In our search for a replacement, we found that the Cooler Master SickleFlow fan fits all of our requirements as a replacement fan to the long-lived green Antec TriCool.
Fan grills are a component in a computer that is often underestimated in terms of their contribution to both system noise and airflow. Most often, grills are chosen based on aesthetics with only a small thought towards performance. In this article, we will be examining nine different grills to determine the effects of grill design on both noise and airflow.
