A few weeks ago, the YouTuber Austin Evans (opens in new tab) published a video where he took various measurements of the new revision of PS5, and compared them to the original model. He discovered that the PS5 was outputting more heat out the back, and upon taking it apart, concluded this was down to a smaller heatsink not doing its job as efficiently as the original.
But some — including my colleague Marshall Honorof — have pointed out that a higher exhaust temperature isn’t the same thing as hotter components. All that proves is that more heat is being removed from the casing, which could in fact point to more efficient cooling.

Further testing was clearly required, and the first sets of results are in and looking far more positive for Sony.
First Hardware Busters has published a video (opens in new tab) where the team attached sensors to different parts of the two PlayStation 5 revisions. And while the exhaust temperature was indeed lower on the original hardware, the video found that the CPU was running 11º C cooler on the newer model, with a modest 1.5º C rise to VRM temperature. The memory was running 7.5º C higher, but overall it certainly cast doubt on the original worries of a cheaper build.
But to convince people further, Hardware Busters put out a second video in partnership with Igor’s Lab where a massive 12 sensors were installed in the new PS5 and then compared to temperatures measured from a launch PS5 by Gamers Nexus at an earlier date.
Obviously, that’s not an ideal comparison due to potential environmental differences (and the fact that the original analysis used fewer measurements), but it should give you a general idea all the same. Here are the results:
Generally, it seems to be a big improvement for the revised hardware across the board, despite the higher ambient temperature of the lab, with temperatures ranging from 6- to 20-degrees lower on the revised hardware. The tests also revealed similar power consumption, with a slight increase on the new model when idle.
No doubt further testing will be done to eliminate any remaining doubt and ensure identical conditions for revisions, but even with the data we have, it seems pretty clear that anybody purchasing a new model of PS5 has little to worry about in terms of long-term reliability.
It seems that Sony was right to reduce the weight of the PS5, and take full advantage of all the cost savings derived from producing a lighter product.
