Airflow Imaging: NVIDIA RTX 3080 Founders Edition Schlieren Photography

Using Schlieren photography techniques, we're able to show NVIDIA RTX 3080 Founders Edition airflow paths and behaviors. This is new to us, and we have a lot to learn for the future.

Thank you for 1 million subscribers! It's been a crazy ~13 years since we started the website, and a crazy 11 on YouTube).

Look at this airflowtograph. In this video, we're using our new Schlieren photography setup for the first time to take images of the airflow pattern of the RTX 3080 Founders card, as we're able to take images of the density gradient of the air. As stated above, this is the first time we've done this, so we still have a lot to learn. Some things we'd like to improve in the future would involve a separate lens for our high-speed camera, so that we can get enough of a zoom to take these images (the focal point is 10 feet away from the mirror!). Other improvements would be additional card comparisons, potential custom glass enclosures to somewhat simulate a PC case surrounding the cards, and just more experience for better analysis. We'll get there -- give us time -- but this was a fun introductory test case with a lot of interesting airflow patterns.
