The much-anticipated PS5 Pro has arrived with an innovative upgrade designed to address a notable concern of its predecessor. Console experts and repair enthusiasts have been abuzz with the revelation discovered by Steve Porter, a YouTuber who operates TronicsFix. Porter’s teardown of the new PS5 Pro unveils a redesigned heatsink featuring machine-grooved architecture. This enhancement is engineered to mitigate potential leaks of the liquid metal thermal interface material (TIM), especially when the console is positioned vertically.
The original PlayStation 5 experienced some trepidation among users regarding the possibility of liquid metal leakage, which although largely debunked, was not entirely unfounded. Adverse effects such as dry spots and oxidation on the die could surface due to contamination or the inherent volatility of liquid metal. The release of the PS5 Pro signifies a strategic step by Sony to ease these issues.
The new heatsink’s grooves aren’t merely a design flair; they play a functional role by retaining the liquid metal TIM more securely. This modification potentially prevents it from pooling at the bottom of the die—a flaw that led to thermal inefficiencies and necessitated laborious console repairs.
Steve Porter’s insightful examination sheds light on the grooved design, which appears to substantially boost the surface area for heat dissipation, promising an overall improved cooling performance. While traces of liquid metal outside the grooves were noted, the majority remained neatly contained within them.
In an informal stress test, Steve simulated an accident by dropping the PS5 Pro from a few inches above a desk, subsequently re-examining the internal structure for displacement. The grooves proved successful in maintaining the liquid metal’s position, suggesting a promising solution to prior concerns.
Despite these promising findings, definitive assessments will only emerge with prolonged use. The PS5 Pro’s new feature sets a positive precedent for gamers looking for longevity and performance efficiency, paving the way for a potentially smoother gaming experience. Whether this engineering marvel will live up to expectations in the long term remains to be seen, but the signs are promising for Sony’s latest console iteration.
