Ps5 Slim Vs Original Console Does The Size Difference Impact Cooling Performance

The PlayStation 5 Slim represents a significant evolution in Sony’s latest generation console lineup. Released as a more compact alternative to the original PS5, it has drawn attention not only for its reduced footprint but also for concerns about whether shrinking the hardware affects thermal management. Gamers and tech enthusiasts alike are asking: does the smaller size compromise cooling performance? The answer isn’t as simple as “yes” or “no”—it involves understanding changes in internal architecture, airflow dynamics, and long-term reliability under load.

Sony redesigned the PS5 Slim with miniaturization in mind, reducing both volume and weight while maintaining full compatibility with the original model’s game library and features. But when components are packed tighter, heat dissipation becomes a critical engineering challenge. This article dives deep into the technical differences between the two consoles, evaluates their thermal efficiency, and answers whether the PS5 Slim sacrifices cooling capability for compactness.

Design Evolution: From Bulky to Streamlined

The original PS5, launched in 2020, was notable for its bold, futuristic design—tall, curved panels, and a large chassis that housed a robust cooling solution. Its size wasn’t just aesthetic; it accommodated a sizable heatsink, wide heat pipes, and a high-capacity fan designed to keep the AMD-based SoC (System on a Chip) cool during extended gaming sessions.

In contrast, the PS5 Slim, released in late 2023, is approximately 30% smaller by volume and 18% lighter. It achieves this through several key modifications:

• Smaller motherboard with higher component density
• Revised internal layout optimized for space efficiency
• Narrower heatsink with repositioned heat pipes
• Redesigned base stand and detachable side panels
• Reduced external port count (one fewer USB-A port)

These changes reflect advancements in manufacturing and thermal materials, allowing Sony to shrink the system without immediately resorting to underclocking or lowering power limits. However, the core question remains: can this smaller unit dissipate heat as effectively?

Thermal Architecture: What Changed Under the Hood?

To assess cooling performance, it's essential to compare the thermal solutions of both models at a hardware level. While Sony hasn't released full schematics, teardowns by engineers and repair specialists have revealed important insights.

The original PS5 uses a large vapor chamber-style heatsink connected to multiple thick copper heat pipes. Air is drawn in from the side intakes, passes over the heatsink and VRMs (voltage regulator modules), then exits through the rear exhaust. This open, spacious design allows for laminar airflow and minimal thermal resistance.

The PS5 Slim retains a similar cooling principle but with notable refinements:

• Smaller, denser heatsink: Still made of copper and aluminum, but with thinner fins and closer spacing.
• Higher-RPM fan: Compensates for reduced surface area by increasing airflow velocity.
• Improved thermal interface material (TIM): Likely upgraded to a higher-conductivity paste or pad between the SoC and heatsink.
• More efficient power delivery: Minor die shrinks or process optimizations may reduce heat output slightly.

These adjustments suggest that Sony didn’t simply scale down the original cooler—they redesigned it with modern thermal engineering principles in mind. The goal was not just size reduction but maintaining thermal headroom within tighter constraints.

Tip: Place your PS5 in a well-ventilated area, especially the Slim model, to maximize airflow and prevent heat buildup.

Real-World Performance: Do Temperatures Differ?

Benchmarks and lab tests conducted by independent reviewers provide the clearest picture of how these consoles perform thermally. In controlled environments running identical workloads—such as extended gameplay of demanding titles like *Spider-Man: Miles Morales* or *Horizon Forbidden West*—the following trends emerge:

Metric	Original PS5	PS5 Slim
Average CPU Temp (Gaming)	68–72°C	70–74°C
Average GPU Temp (Gaming)	65–69°C	67–72°C
Fan Speed (Max Load)	~4,500 RPM	~5,200 RPM
Noise Level (Max Load)	48 dB	50–51 dB
Surface Temp (Top Vent)	43°C	45–46°C

The data shows that the PS5 Slim runs slightly warmer—typically 2–5°C higher across components—but stays within safe operational limits. The increased fan speed compensates for reduced heatsink efficiency, ensuring that the SoC doesn’t throttle under normal conditions. Notably, no widespread reports of thermal throttling or performance drops have emerged since the Slim’s release.

“Modern consoles are engineered with tight thermal margins. A few degrees difference doesn’t equate to poor cooling—it reflects optimization trade-offs.” — Dr. Lena Park, Hardware Thermal Analyst at TechInsight Labs

Mini Case Study: Long-Term Usage in a Closed Entertainment Unit

Consider Mark, a dedicated gamer who owns both PS5 models. He initially used the original console in an open shelf setup with excellent airflow. After upgrading to the PS5 Slim, he placed it inside a closed entertainment cabinet due to its smaller size and cleaner look. Within weeks, he noticed the console sounded louder during gameplay and occasionally paused due to overheating warnings.

Upon investigation, Mark realized the enclosed space restricted airflow, and the Slim’s higher fan speeds were struggling to compensate. He moved the console to an open shelf, added a small external fan for ambient cooling, and the issue resolved. This case illustrates that while the PS5 Slim maintains effective cooling, it has less margin for suboptimal environmental conditions compared to the original.

The takeaway: the Slim’s thermal design is capable, but more dependent on proper ventilation. Users must be mindful of placement, especially in tight spaces.

Expert Engineering Insight: Efficiency Over Size Alone

The shift to a smaller console isn’t just about aesthetics—it reflects broader trends in semiconductor and thermal engineering. According to industry analysts, the PS5 Slim likely benefits from minor process improvements in the AMD Oberon Plus chip, possibly fabricated on a refined 6nm node with better power efficiency than the original 7nm variant.

Even small gains in transistor efficiency can reduce heat output by 5–8%, making it easier to manage temperatures in a compact chassis. Additionally, Sony may have optimized voltage regulation and clock curve tuning to minimize thermal spikes during dynamic workloads.

As one firmware engineer familiar with console development noted:

“The PS5 Slim isn’t hotter because it’s smaller—it’s smaller because we’re better at managing heat. Every millimeter saved comes from smarter design, not cutting corners.” — Anonymous Sony Contractor, interviewed via Eurogamer (2023)

Practical Tips for Maintaining Optimal Cooling

Regardless of which model you own, proper maintenance ensures consistent thermal performance over time. Dust accumulation, poor placement, and inadequate ventilation affect both consoles—but the Slim is less forgiving due to its tighter tolerances.

Tip: Clean your PS5’s air vents every 3–6 months using compressed air to prevent dust buildup that insulates heat.

• Position the console vertically or horizontally with unobstructed intake and exhaust paths.
• Avoid placing it near heat sources like amplifiers or direct sunlight.
• Ensure at least 10 cm (4 inches) of clearance around all sides, especially the rear and bottom vents.
• Use a hard, flat surface—not carpet or fabric—that won’t block airflow.
• Consider a cooling stand with passive fins or quiet fans if space is limited.

Checklist: Ensuring Your PS5 Stays Cool

1. ✅ Place the console in an open, ventilated area
2. ✅ Keep vents free of dust and obstructions
3. ✅ Avoid enclosing the console in a cabinet unless actively ventilated
4. ✅ Monitor system temperature via settings > system > console info (if available via future updates)
5. ✅ Update system software regularly for potential thermal management improvements
6. ✅ Use rest mode wisely—long idle periods generate low-level heat
