Schlieren photography is useful for visualizing air patterns and movement when the air density has a gradient -- or a change in density -- surrounding a product. This isn't a perfect testing method and doesn't tell us thermal performance (we use thermocouples for that, and the Series X thermals will be uploaded in a few days), but it does tell us how the air exits the consoles, how obstructed it might be, and what directions it takes. This also allows us to the opportunity to closer analyze the console's internal heatsink design: Even though we can't see the heatsink with this imaging, we can see how the air exits the device and at what angle, and speed, and all of these factors allow us to better understand the finstack impedance and angles. The Sony PlayStation 5 already had thermal testing in one of our previous pieces, with the Xbox Series X thermals coming up soon.
