A YouTuber has unveiled the mystery behind the weight reduction of the new PS5 model. Austin Evans found that Sony changed the heat sink and replaced it with a significantly smaller one, taking the machine apart piece by piece. Due to the small size of the heatsink, however, it seems that the console heats a few degrees more than the launch version. Evans has disassembled a Digital Edition. For now, it remains to be clarified whether the heatsink has also been changed to the version with a disk drive.
A new PS5 model began appearing in Australia, Japan, and parts of the US earlier this month, with a new stand design and mysterious weight reduction. Thanks to a teardown video from YouTuber Austin Evans, the mystery has now been solved: Sony has changed the heatsink that helps cool the PS5.
According to Evans, the new heatsink is significantly smaller than the original and offsets the entire 300 gram (0.6 lb) weight reduction. It’s unclear why Sony replaced the heatsink so soon, but Evans notes that his particular drive overheated as a result, with rear exhaust temperatures about 3-5 degrees higher. However, this could be due to manufacturing variance.
Sony uses this heat sink to cool the PS5, and the console has a heat pipe with a shape and airflow designed to create the same level of performance as a vapor chamber. The heat sink, hard copper plate, and aluminum dissipation fins take up a significant amount of space inside the PS5 and contribute greatly to its overall size.
Evans concludes that the changes make the PS5 worse due to the extra heat it registered. “I don’t think it’s a bad thing this is a worse console, at least for thermals and cooling,” Evans says. “As far as I’m concerned, I’d rather have a launch PS5.”
Evans has only opened a Digital Edition version of the PS5, so we don’t know if Sony has also changed the cooling unit on the model with a hard drive.
