Console Repairer Unveils Innovative PS5 Pro Heatsink Design with Machined Grooves to Prevent Solder Paste Leakage

Sony’s introduction of the new PlayStation 5 Pro includes a subtle yet fascinating change in the design of its heatsink. It appears that TronicsFix, a popular console repair channel on YouTube, made the discovery that this PS5 Pro heatsink isn’t the typical smooth design we’re used to seeing. Instead, it boasts a unique rectangular spiral pattern on its surface.

TronicsFix suggests that this intentional patterning could play a role in minimizing dry spots and preventing oxidation that might occur when liquid metal thermal interface material (TIM) spreads over the heatsink. The channel also hints that this design tweak might subtly increase the contact area with the cooling system.

If you’ve dabbled with liquid metal, you’re probably aware of its tendency to pool and wander into places it shouldn’t, a behavior that differs significantly from traditional thermal pastes. Systems utilizing liquid metal for heat dissipation often incorporate a seal or barrier around the heatsink. This precaution ensures that the conductive material doesn’t leak and jeopardize other components.

Additionally, TronicsFix notes that the liquid metal’s movement may be more pronounced in PlayStation systems that are used vertically. Given TronicsFix’s extensive experience with PS5 repairs, their insights might well be right on the mark regarding these potential issues.

It’s intriguing to see Sony opt for these spiral grooves, especially since such a design seems counter to traditional cooling strategies. Enthusiasts often try to achieve a mirror-like finish on their heatsinks for optimal heat transfer, but the use of liquid metal has changed these standards. Sony likely carried out a series of tests comparing this new heatsink structure to the traditional smooth designs and found this adaptation beneficial for thermal performance.

With the PS5 Pro packing enhanced processing capabilities, particularly a more potent GPU, it’s reasonable to assume these heatsink grooves are a deliberate effort to prevent thermal throttling from becoming a concern.

Though the PS5 Pro was officially revealed in early September, it has only recently hit the shelves for consumers. As enthusiasts and experts continue to dismantle and scrutinize its design, we’re learning more about its innovative features. Many technical specifications were initially shared by lead architect Mark Cerny during the product’s launch live stream, offering us a deeper look into this upgraded console.
