In the video, Jay conducts a comparative analysis between static pressure (SP) and airflow (AF) optimized fans, both Corsair 120 mm quiet edition models running at 1,200 RPM, on the same radiator. Using an EVGA GTX 1080 hybrid graphics card with a 120 mm radiator, Jay's initial tests show the SP fan achieving a baseline temperature of 49-50°C and a peak of 51°C. He uses paper tests to visually demonstrate the differences in airflow, observing less movement with the AF fan, indicating lower airflow. The speaker notes temperature variations of 54-56°C during high-performance tests, highlighting a minimal temperature impact due to fan type and emphasizing that radiator surface area has a more significant effect on cooling efficiency. They suggest that increasing the radiator size to 240 mm would reduce temperature differences and invite viewers to explore related content on fan setups.

In this part of the video, Jay discusses his plan to compare a static pressure optimized fan and an airflow optimized fan on the same radiator, using a consistent setup to determine the real differences based on fan type. He explains that both fans are Corsair 120 mm quiet edition fans running at a maximum of 1,200 RPM—one being an SP (static pressure) and the other an AF (airflow). The test involves using an EVGA GTX 1080 hybrid graphics card with a 120 mm all-in-one radiator, operating at 4K until temperatures stabilize. Initial results with the static pressure fan show a baseline temperature of 49-50°C, hitting a maximum of 51°C. Jay then points out that he uses paper on the radiators to visually compare the airflow between the fans, noting less paper movement with the AF fan, indicative of lower airflow compared to the SP fan, even though both run at the same speed.

In this segment of the video, the speaker discusses the temperature differences observed during a test involving a high-performance graphics card overclocked to its limits paired with a small 120 mm radiator. The test shows temperature variations around 54-56°C, indicating a 5°C delta during peak spikes and an average delta of 3-4°C. The speaker emphasizes that while static pressure fans are optimized for radiators, the radiator surface area is more critical than fan blade design for cooling efficiency. People should not panic if they use the wrong fan type, as the temperature impact is minimal. The speaker also references another video comparing push-pull fan setups for further understanding. Additionally, they note that increasing the radiator size to a 240 mm would likely reduce temperature differences. The segment concludes by highlighting the ongoing debates about fan setups and inviting viewers to check out related videos.
