A teardown of the Marvel’s Wolverine Limited Edition PS5 Slim has revealed a new internal hardware revision built around an EDM-051 motherboard. Console technician and modder Modyfikator89 documented the changes after opening the system, finding a revised board layout, easier access to the CR2032 CMOS battery and several changes to the cooling assembly. Sony has not publicly announced the revision, and the findings currently come from a single inspected console rather than a confirmed change across every PS5 Slim production run.
One of the most noticeable differences is the motherboard layout itself. Components have been rearranged and the overall internal design appears to be simplified compared with earlier PS5 Slim revisions. The CR2032 CMOS battery can also be removed and replaced more easily, improving serviceability if the battery eventually needs to be changed.
The HDMI retimer implementation has reportedly been revised as well. Modyfikator89 described the newer solution as a lower-cost and more optimized design, although there is no evidence that the change improves image quality or gaming performance. As with many console revisions, the redesign appears to balance manufacturing efficiency with component consolidation rather than introduce a new feature for players.
Cooling receives the more technically interesting changes. Sony continues to use liquid metal between the PS5’s custom AMD APU and its heatsink, but the containment structure surrounding the processor has been redesigned. The newer barrier reportedly leaves less liquid metal exposed and more closely resembles the approach used in the PS5 Pro, which should help keep the conductive material confined around the die.
The heatsink itself has also changed. According to the teardown, its construction and materials differ from earlier PS5 Slim models, suggesting Sony has continued refining the thermal design even after previous Slim revisions already altered the cooling system. However, there are currently no controlled temperature, fan-noise or sustained-performance tests showing that EDM-051 actually runs cooler than existing retail models.
That distinction matters because the new revision should not be treated as a performance upgrade. There is no indication that the APU, memory configuration or core gaming specifications have changed, and the teardown does not show any improvement in frame rates. The likely benefits are instead related to manufacturing, thermal reliability and repairability over the life of the console.
Sony has repeatedly adjusted PlayStation hardware internally without giving each revision a major public announcement. Smaller motherboard changes, cooling revisions and component substitutions are common during a console generation as manufacturers reduce costs, address reliability concerns and adapt to available parts. The latest PS5 Slim motherboard and cooling changes fit that pattern rather than representing a new model generation.
The fact that the revised board appeared inside the Marvel’s Wolverine Limited Edition bundle also does not yet establish how widely EDM-051 is shipping. Retail PS5 Slim units can move through different production batches, and Sony has not identified the revision through new branding or packaging. Buyers therefore may have no straightforward way to know which motherboard is inside a particular console without checking the hardware directly.
The easier CMOS battery access is one of the more practical improvements for long-term ownership. A replaceable CR2032 battery is inexpensive and widely available, but reaching it in older electronics can require substantial disassembly depending on the design. Making the battery easier to service reduces one potential maintenance barrier as current-generation consoles age.
For now, the EDM-051 revision is best viewed as an internal engineering update rather than a reason for existing PS5 Slim owners to replace their consoles. The new liquid-metal containment, revised heatsink and more accessible CMOS battery could improve reliability and serviceability, but broader conclusions will require more teardown samples and direct thermal testing. Sony has not confirmed whether the revision is exclusive to newer production batches or will become standard across all PS5 Slim units.
