The old PS5 heat sink (left) vs. brand-new PS5 heat sink (right).

Its not clear why Sony has actually swapped out the heatsink so early on in the PS5s lifecycle, but Evans does note that his particular system ran hotter as an outcome– with rear exhaust temperatures around 3 to 5 degrees greater. Sony utilizes this heatsink to cool the PS5, and the console has a heat pipe with a shape and air flow thats created to create the exact same level of performance as a vapor chamber. Its intriguing to see Sony decrease the size of this part, and Im hoping this could be the first sign of the company working towards a smaller sized PS5 model.

A brand-new PS5 model began appearing in Australia, Japan, and parts of the United States earlier this month, with a brand-new stand design and a mysterious decrease in weight. Thanks to a teardown video from YouTuber Austin Evans, the secret has now been solved: Sony has changed the heatsink that assists cool the PS5.
The new heatsink is significantly smaller than the original, and makes up for the whole weight reduction of 300 grams (0.6 pounds), according to Evans. Its not clear why Sony has swapped out the heatsink so early on in the PS5s lifecycle, however Evans does keep in mind that his particular system ran hotter as an outcome– with rear exhaust temperature levels around 3 to 5 degrees greater. That might be down to manufacturing difference.

Sony uses this heatsink to cool the PS5, and the console has a heat pipeline with a shape and air flow thats developed to produce the same level of efficiency as a vapor chamber. The heatsink, difficult copper plate, and aluminum dissipation fins all use up a substantial amount of area inside the PS5, and contribute considerably to its general size. Its interesting to see Sony decrease the size of this part, and Im hoping this could be the first sign of the company working towards a smaller sized PS5 design. The PS5 is the biggest game console in modern-day history.
Evans does conclude that the modifications make the PS5 worse though, due to the extra heat he taped. That might well make the launch PS5s more preferable, if its something we see reproduced in other places.
The revision comes just as Sony exposes its no longer offering the $499 variation of the PS5 at a loss, and after reports in 2015 suggested Sony was fighting to keep the PS5 costs down thanks in part to its costly cooling solution. Evans has just opened a Digital Edition version of the PS5, so we do not know for sure whether Sony has actually also altered the cooling unit on the model with a disc drive.
