Ps5 Slim Vs Original Ps5 Is The Size Reduction Actually A Downgrade In Cooling

When Sony unveiled the PS5 Slim in late 2023, many gamers welcomed the more compact form factor as a natural evolution of the original console. But with a smaller chassis comes a critical question: has the internal redesign compromised the system’s ability to manage heat? The concern isn’t unfounded—thermal performance directly affects longevity, noise levels, and even sustained processing power. This article dives deep into the engineering behind both models, comparing their cooling solutions, real-world thermal behavior, and whether the size reduction represents a meaningful trade-off.

Design Evolution: From Bulky to Compact

The original PS5 launched in 2020 with a bold, futuristic design that prioritized airflow over minimalism. Its dual white fins and wide vents were not just aesthetic choices—they served as part of an expansive internal cooling architecture. The large chassis allowed for a substantial heatsink, multiple heat pipes, and generous spacing between components, all contributing to efficient heat dissipation.

In contrast, the PS5 Slim reduces volume by nearly 30%, trimming down both height and depth. To achieve this, Sony redesigned the motherboard, used a smaller optical drive (in the disc version), and introduced a new internal layout. Most notably, the heatsink is visibly smaller, and the fan now sits lower in the casing. While the exterior maintains a similar visual language, the internals tell a different story—one of tighter integration and component miniaturization.

This shift reflects broader industry trends toward denser hardware, driven by advancements in semiconductor efficiency and manufacturing. The PS5 Slim leverages a revised 6nm AMD SoC (codenamed Oberon Plus), which generates less heat than the original 7nm chip. This die shrink plays a crucial role in enabling a smaller cooling solution without necessarily sacrificing performance stability.

Cooling Architecture Compared

To understand whether the PS5 Slim’s cooling is truly inferior, it's essential to examine how each model manages heat under load.

The original PS5 uses a vapor chamber-style heatsink with five heat pipes spreading across the CPU and GPU. Airflow is guided through front intakes, across the motherboard, and out the rear via a 120mm double-sided fan. This setup creates a broad thermal envelope, allowing heat to disperse gradually rather than building up in localized hotspots.

The PS5 Slim replaces the vapor chamber with a more traditional aluminum heatsink and fewer heat pipes. The fan remains 120mm but operates at higher RPMs under load to compensate for reduced surface area. Thermal pads have also been improved, enhancing conductivity from the SoC to the heatsink. Despite the smaller profile, Sony claims the new design maintains equivalent or better thermal resistance metrics.

Independent teardowns and thermal testing support this claim to a degree. In controlled environments, the Slim often runs slightly warmer on average—but rarely exceeds safe operating thresholds. Peak temperatures during extended gaming sessions may reach 6–8°C higher than the original, but throttling has not been observed, indicating that the system still operates within designed parameters.

Performance and Noise: Real-World Implications

Thermal performance isn’t just about temperature readings—it impacts user experience through noise and long-term reliability. A cooler-running system typically allows for slower fan speeds, resulting in quieter operation.

In side-by-side tests, the original PS5 tends to operate more quietly during moderate loads, such as menu navigation or streaming. Its larger heatsink absorbs heat spikes more effectively, reducing the need for aggressive fan response. Under peak gaming loads, however, the difference narrows. Both models ramp up fan speed significantly when rendering demanding titles like *Spider-Man: Miles Morales* or *Horizon Forbidden West*.

The PS5 Slim’s fan can be noticeably louder during sustained gameplay, particularly in its default vertical orientation. Horizontal placement appears to improve airflow marginally, suggesting that positioning still matters—even in the newer model. However, no reports indicate coil whine, shutdowns, or frame rate drops due to overheating, reinforcing that the system’s thermal management remains effective.

Tip: Place your PS5 in a well-ventilated area, avoid enclosing it in tight cabinets, and keep vents free of dust to maximize cooling efficiency—especially important for the Slim model.

Longevity and Reliability Concerns

A persistent myth in gaming communities suggests that higher operating temperatures shorten console lifespan. While extreme, prolonged heat can degrade solder joints and capacitors over time, modern consoles are engineered with wide safety margins. The PS5’s silicon is rated for operation up to 90–95°C, and both models consistently stay below that threshold.

What matters more than peak temperature is thermal cycling—the repeated expansion and contraction of components as the system heats and cools. Frequent power cycles exacerbate this stress. Users who leave their PS5 in rest mode rather than fully powering down may actually reduce wear over time, as the system maintains a stable thermal baseline.

The PS5 Slim’s more compact design could theoretically increase the risk of dust accumulation in tighter spaces, potentially insulating the heatsink over months of use. Regular maintenance becomes even more critical. Unlike laptops or PCs, the PS5 is not user-serviceable, so cleaning is limited to external vent brushing and environmental control.

Mini Case Study: Two Gamers, Two Consoles

Consider two users: Alex owns the original PS5, purchased at launch, and plays 15–20 hours per week. Jamie bought the PS5 Slim at release and has a similar usage pattern. Both keep their consoles in open entertainment centers, away from direct sunlight, and clean vents every three months.

After one year, telemetry data from system diagnostics shows Alex’s console averaging 70°C under load, with fan speeds peaking at 4,800 RPM. Jamie’s Slim reaches 77°C on average, with the fan hitting 5,200 RPM during intense sequences. Neither experiences performance drops, and both report satisfaction with reliability.

However, Jamie notes the fan noise is more intrusive during quiet game moments, prompting a switch to headphones. Alex appreciates the quieter background operation but acknowledges the original’s bulk makes cable management harder. Neither has encountered errors or overheating warnings.

This scenario illustrates that while thermal differences exist, they don’t necessarily translate into functional drawbacks. User tolerance for noise and space constraints may matter more than raw temperature metrics.

Actionable Checklist for Optimal Cooling

• Ensure adequate clearance: Leave at least 4 inches of space around all vents, especially the rear exhaust.
• Use horizontal or vertical consistently: Switching orientations frequently can disrupt airflow patterns; pick one and stick with it.
• Dust regularly: Use a soft brush or compressed air to clean intake grills every 2–3 months.
• Avoid enclosed spaces: Never place the console inside a closed cabinet or between tightly packed devices.
• Monitor ambient temperature: Keep room temperature below 25°C (77°F) for optimal performance.
• Update firmware: Sony occasionally releases updates that refine fan curves and thermal management logic.

Frequently Asked Questions

Does the PS5 Slim overheat more than the original?

No, the PS5 Slim does not “overheat” in the technical sense. It runs slightly warmer under load due to a smaller heatsink and denser layout, but it stays within safe operating limits. No throttling or shutdowns have been reported under normal conditions.

Is the smaller size worth the potential heat trade-off?

For most users, yes. The PS5 Slim offers the same performance in a more space-efficient package. The minor increase in temperature and noise is unlikely to impact gameplay or longevity, especially with proper ventilation.

Can I replace the thermal paste or upgrade the cooling in either model?

While technically possible, neither console is designed for user modification. Opening the device voids the warranty and risks damaging internal components. Sony does not support aftermarket cooling upgrades, and doing so may lead to instability or failure.

Step-by-Step Guide to Maintaining Console Temperature

1. Position the console correctly: Place it on a hard, flat surface with full access to intake and exhaust vents.
2. Check airflow monthly: Run your hand near the exhaust to feel consistent hot air output. Weak airflow may indicate dust buildup.
3. Power down weekly: Fully shut off the system at least once a week to allow complete cooling and reset thermal sensors.
4. Clean external vents: Use a dry microfiber cloth or low-pressure air duster to remove surface dust.
5. Monitor performance: If games begin stuttering or the system shuts down unexpectedly, check for overheating signs and consider professional servicing.

Final Verdict: Smaller, Not Weaker

The PS5 Slim’s size reduction is not a downgrade in cooling performance—at least not in any practical sense. While it runs warmer and slightly louder than the original, it achieves this within the boundaries of a more efficient chipset and refined thermal materials. The engineering trade-offs reflect progress, not regression.

What was once a necessity—large cooling systems for power-hungry chips—is giving way to smarter, denser designs made possible by process node improvements. The PS5 Slim proves that miniaturization can coexist with reliability when paired with thoughtful engineering.

Ultimately, the choice between models should hinge on personal preference: do you value footprint and aesthetics more than marginal noise differences? For apartment dwellers, minimalist setups, or those upgrading from older hardware, the Slim is a compelling option. For audiophiles sensitive to fan noise or collectors who appreciate the original’s statement design, the launch model retains its appeal.
