Even with a part that seems as simple as a fan, consoles can require a lot of custom work. Dellinger pointed out that the X's struts are straight where the S's are curved, and they're on opposite sides if the S fan is exhausting air, too. (Image credit: Microsoft)Īre the Series S and Series X using the same 130mm fan? Even if it's the same part, the way the fans in the two systems work in practice could be pretty different. The Xbox Series S fan grille makes it look like a speaker, but it should pay off with serious ventilation. This may be required from a visual design or EMI perspective but it definitely introduces extra airflow resistance, which isn't ideal from a cooling perspective." "In the exploded view, it also looks like there are two layers of fan grills. The big fan on top "could also be an intake fan," Dellinger told me. The smaller Series S has grilles on what would be the bottom if you stood it vertically, but it also has holes on other sides to compensate for that orientation. The Series X draws its air in from the bottom, which is why it has a stand that will raise it up a few millimeters for ventilation. This illuminates one of the challenges of console design: they almost always have to work vertically or horizontally, which limits where you can place intake fans. Even if the fan exhausts to the top, fresh air needs to be drawn in from the sides rather than from the bottom, so the fan will have to do all the work." "Assuming that the fan exhausts, it certainly seems to use much less of a chimney effect because the case is much slimmer, so it probably relies much more on forced convection rather than natural convection. Without a teardown, it's hard to know exactly how the Series S's cooling will work, but Dellinger had a couple thoughts. What about the Series S? No console has ever had a giant fan right over its processor before, or purposefully made the fan a core part of the aesthetic. Microsoft says "the vapor chamber in the Xbox Series X enables evenly spread temperatures with the core and memory." (Image credit: Microsoft)
