A year after the release of the PS5, Sony decided to rethink the console, make minor changes, and make a major upgrade in the cooling department. This update has a new, smaller heatsink, which has shown lower cooling performance, but as it turns out, it's not linear.
The first experiments by Austin Evans, although limited, concluded that the output temperature of the updated model was between 3 and 5 degrees Celsius warmer. In this video, Austin also compares the new system's cooling solution to the "old" console and shows the differences in different sizes, materials, fixtures and fans. Another difference mentioned by the YouTuber is the Wi-Fi antenna setup, but no tests have been done on it.
A higher outlet temperature does not in itself prove that the system performs worse in cooling. It just shows that the air leaving the console is warmer. This can be due to a number of reasons, including the new placement of the heatsink. Higher outlet temperatures also result from efficient cooling, not just hot components.
Other experiments were performed by HardwareBusters using sensors attached to various parts of the control unit, including VRM, exhaust, and VRAM. According to the data, the CPU in the new PS5 console is 11°C cooler, from 51°C to 40°C. In terms of memory and VRM temperature, they increased by 7.5 °C and 1.5 °C, respectively. The output temperature of the old PS5 was about 2.5 degrees Celsius lower.
However, that wasn't the end of it. Following the unfortunate claims of HardwareBusters' testing method, the YouTube channel has partnered with LAB Igor to take new measurements to compare test results from the older PS5's GamerNexus. Instead of comparing the measured temperature, they used the ambient temperature to better show the difference between the two models.
< p > Based on the data in the table, the new PS5 model is generally superior to the old console. Although some values are not comparable due to lack of data on the old PS5, we can still check the improvement of VRM, memory and APU temperature. As we saw in the first trials done by HardwareBusters, it was a real surprise in the VRM and memory. Both were cooler than the PS5 GamerNexus, with temperatures around 9°C lower and memory temperatures ranging from 6.4°C to 20.4°C.
Other tests by HardwareBusters show that fan cycle performance was roughly the same between the old and new models, but the noise measured in the latter was slightly higher in the standby mode. The power consumption of the two models was very similar during the game, and the new one was somewhat more inclined. On the home screen, an updated PS5 consumes less power.
