Ps5 Slim Vs Original Ps5 Is The Smaller Size Actually Helpful For Cooling

When Sony unveiled the PS5 Slim in late 2023, it marked a significant shift in console design philosophy. The new model reduced the overall footprint by nearly 30%, weighing less and featuring a more compact chassis. While many welcomed the smaller form factor as a welcome upgrade for entertainment centers with limited space, a pressing question emerged: does shrinking the console compromise its ability to stay cool under load? More specifically, is the smaller size of the PS5 Slim actually helpful—or even neutral—for cooling, or does it introduce new thermal challenges compared to the original PS5?

This isn’t just about aesthetics or convenience. Thermal management directly affects performance, longevity, noise levels, and user experience. A poorly cooled system can throttle processing power, shorten component lifespan, and generate excessive fan noise. To understand whether the PS5 Slim’s design improves, maintains, or undermines cooling efficiency, we need to examine internal architecture, airflow dynamics, real-world testing data, and engineering trade-offs.

Design Evolution: From Original PS5 to PS5 Slim

The original PS5, released in 2020, was notable not only for its powerful hardware but also for its bold, futuristic design. Standing at approximately 390mm tall and weighing around 4.5kg (for the disc edition), it was one of the largest consumer consoles ever made. Its size wasn’t arbitrary—Sony engineers used the generous volume to incorporate a large heatsink, an expansive heat pipe array, and a 120mm diameter cooling fan capable of moving substantial volumes of air while maintaining relatively low noise levels.

In contrast, the PS5 Slim reduces the height by over 60mm and trims the depth slightly. The weight drops to about 3.2kg for the disc version. Visually, the redesign splits the outer shell into four removable panels, allowing easier access to the SSD expansion bay without requiring screws. But beneath the surface, the changes are more profound.

Sony didn't merely shrink the original internals into a smaller box. Instead, they redesigned the motherboard, used a smaller yet denser power supply unit (PSU), and implemented a more compact heatsink and fan assembly. These modifications reflect advances in component miniaturization and improved manufacturing processes since 2020. However, reducing physical size inherently limits the potential for passive heat dissipation and restricts airflow pathways.

Thermal Architecture: What Changed Internally?

Cooling effectiveness depends on three key factors: heat generation, heat transfer, and heat expulsion. The PS5 Slim retains the same AMD Zen 2 CPU and RDNA 2 GPU architecture as the original, meaning peak thermal output remains similar—around 200–220 watts under full load. What differs is how efficiently that heat is managed.

The original PS5 used a vapor chamber-assisted heatsink with multiple heat pipes spreading thermal energy across a large aluminum fin stack. Air was drawn in from both sides, passed through the heatsink, and expelled out the rear via a wide axial fan. This setup prioritized surface area and laminar airflow, minimizing turbulence and hotspots.

In the Slim model, Sony replaced the vapor chamber with a more traditional copper heat pipe solution and downsized the heatsink. The cooling fan is now 100mm instead of 120mm, though it spins faster and uses a nine-blade design optimized for higher static pressure. Additionally, the internal layout has been reorganized to fit within tighter confines, which alters airflow patterns.

Despite these reductions, early teardowns by iFixit and Digital Foundry revealed that Sony maintained strict attention to thermal interface materials (TIMs) and retained the liquid metal thermal compound between the SoC and heatsink—a high-performance choice that improves heat conduction significantly over standard thermal paste.

Tip: Always place your PS5 in a well-ventilated area, regardless of model. Even efficient cooling systems rely on ambient airflow.

Real-World Cooling Performance: Benchmarks and User Reports

To assess whether the smaller size impacts cooling, several independent labs and tech reviewers conducted side-by-side stress tests using identical games, room temperatures, and positioning. Results show a nuanced picture.

In controlled environments, the original PS5 typically operates with CPU junction temperatures between 70–78°C under sustained gaming loads. The PS5 Slim, under the same conditions, reaches 74–82°C. While slightly warmer on average, these readings remain within AMD’s safe operating range (up to 90–95°C for Zen 2). No evidence of throttling has been observed in either model during normal gameplay.

Noise levels, however, tell a different story. The Slim’s smaller fan must spin faster to move equivalent air volume, resulting in a measurable increase in acoustic output. At peak load, the Slim registers around 48–50 decibels, compared to 44–46 dB on the original. Most users report this as noticeable but not disruptive—more of a consistent hum than a distracting whine.

A mini case study illustrates this in practice:

Mini Case Study: Living Room Setup Comparison

Alex owns both the original PS5 and the PS5 Slim. He runs *Spider-Man: Miles Morales* at 60fps in Performance Mode on both systems, using identical HDMI cables, TV settings, and room temperature (22°C). After 45 minutes of continuous play, he measures:

- Original PS5: Surface temp ~43°C, fan noise barely audible beyond 1 meter.
- PS5 Slim: Surface temp ~46°C, fan produces a steady mid-frequency tone detectable across the room.

While performance is identical, Alex finds the Slim slightly noisier but appreciates its smaller footprint on his crowded media shelf.

Is Smaller Size Helpful for Cooling? A Balanced Answer

The short answer: no, the smaller size is not inherently helpful for cooling—but it doesn’t catastrophically harm it either, thanks to careful engineering.

Physics dictates that larger volumes allow for better heat dissipation. More space means larger heatsinks, longer heat pipes, and slower-moving fans—all contributing to quieter, cooler operation. By reducing size, Sony sacrificed some of that thermal headroom. However, they offset this loss through material improvements, refined airflow channels, and tighter integration of components.

One advantage of the Slim’s design is improved manufacturing consistency. Early original PS5 units showed variability in liquid metal application, occasionally leading to uneven thermal performance. The Slim’s revised assembly process appears to reduce such inconsistencies, offering more predictable cooling behavior across units.

Additionally, the modular panel system allows easier cleaning of intake grills—an indirect benefit for long-term cooling. Dust buildup is a major contributor to rising internal temperatures over time, and the Slim’s tool-free access encourages maintenance.

“Smaller consoles aren’t inherently worse for cooling—but they leave less margin for error. Sony’s use of liquid metal and precision fan tuning keeps the PS5 Slim thermally viable despite the reduced volume.” — Dr. Lena Park, Hardware Thermal Systems Engineer

Best Practices for Optimal Cooling (All Models)

Regardless of whether you own the original or Slim PS5, proper placement and maintenance are critical for long-term thermal health. Follow this checklist to ensure your console stays cool and performs reliably:

• Provide clearance: Leave at least 10cm of space on all sides, especially near intake vents (sides) and exhaust (rear).
• Avoid enclosed spaces: Never place the PS5 inside a closed cabinet or tight shelf without ventilation.
• Keep vents clean: Use compressed air every 3–6 months to remove dust from intake grills.
• Use vertical or horizontal position correctly: If placing horizontally, ensure the base is securely attached to prevent airflow blockage.
• Monitor ambient temperature: Avoid running the console in rooms above 28°C for extended periods.
• Consider external aids: In particularly hot environments, a dedicated console cooling stand with quiet fans may help, though it’s rarely necessary.

Tip: If you notice increased fan noise over time, check for dust buildup first—it’s the most common cause of thermal strain.

FAQ: Common Questions About PS5 Cooling

Does the PS5 Slim run hotter than the original?

Yes, slightly. Internal measurements show the Slim runs 3–5°C warmer on average under full load. However, this difference is within safe operational limits and does not affect performance or longevity.

Can poor cooling damage my PS5 over time?

Prolonged exposure to high temperatures can degrade capacitors and other components, potentially shortening lifespan. However, both PS5 models include robust thermal safeguards that will throttle performance or shut down the system before critical damage occurs.

Should I choose the original PS5 over the Slim for better cooling?

If ultimate silence and maximum thermal headroom are your top priorities, the original model has a slight edge. But for most users, the Slim’s compact design, lower cost, and comparable real-world performance make it the more practical choice. The cooling difference is minor in everyday use.

Conclusion: Size Isn’t Everything—Engineering Is

The PS5 Slim proves that thoughtful engineering can overcome the thermal disadvantages of miniaturization. While the smaller size doesn’t enhance cooling—it technically constrains it—Sony compensated with smarter design choices: retained liquid metal, optimized fan blades, and improved manufacturing control. The result is a console that stays within safe thermal limits, performs identically to its predecessor, and fits more easily into modern living spaces.

Cooling isn’t just about raw capacity; it’s about balance between efficiency, noise, size, and reliability. The PS5 Slim strikes that balance effectively. For the average gamer, the reduction in footprint far outweighs the marginal increase in temperature and fan noise. And with proper care, both models should deliver years of stable, high-performance gaming.
