New test shows that PS5's smaller, lighter heatsink helps it stay cooler

Last month, Sony started to release a new version of PlayStation 5: the design is slightly different, and the machine is lighter than before. After peeling off the new version, we see the heatsink - the metal pieces responsible for transferring the heat generated from the electronics to another medium, be it water or air - noticeably smaller.

Tested more closely, YouTuber Austin Evans found that the air coming out of the heatsink was hotter than the previous PS5 version. Therefore, Austin Evans temporarily concludes that the new version is hotter.
The heatsink size is different in the old and new versions.
However, in a new test conducted by Hardware Busters International , we see a different result. The air coming out of the heatsink is hotter, which means that the heatsink is doing its job well: getting more heat out of the machine.

The Hardware Busters team measured the device's temperature while running Devil May Cry 5 and saw noticeable differences in the two PS5 versions. It is true that the heat emitted by the new version is several degrees Celsius higher, but the APU (hardware that combines the power of both CPU and GPU) is up to 11 degrees Celsius cooler, down from 51 degrees Celsius to 40 degrees Celsius.

The temperature graph shows that the machine is cooler than before.
The new PS5 version's VRM voltage regulator module and memory are still higher than the old one; The VRM was about 1.3 degrees Celsius hotter and the memory temperature increased by 7 degrees Celsius. However, neither of these numbers affect performance or machine life. A drop of up to 11 degrees Celsius in the APU will compensate for these increases.
This is just a test comparing the two machines. As the number of machines tested increases, it is possible that other variables will emerge. But the new test is still enough to convince consumers to believe in the new PS5 version: a smaller heatsink does not mean a hotter device. If you want to know exactly what product you're about to buy, here's how to tell the difference: the old version has a production code of CFI-1102A, and the newer, lighter version has a CFI-1000.
