MacBook Neo mod uses water cooling to boost performance beyond expectations
Water-cooled MacBook Neo mod boosts performance by over 20%, highlighting the impact of improved thermal design.
The MacBook Neo was originally designed as an affordable, everyday laptop rather than a high-performance machine. Built to handle routine tasks with reliable battery life, it was never intended to compete with more powerful systems or run demanding workloads. However, an unusual modding project has challenged those limitations by dramatically enhancing its performance through an unconventional cooling solution.

The project, carried out by modders known as jakkuh and Zip Tie Tech, set out to address one of the laptop’s most significant shortcomings: heat management. Under sustained workloads, the MacBook Neo reportedly reaches up to 105°C, which can trigger thermal throttling and reduced performance. For the modders, this presented an opportunity to explore how far the device could be pushed beyond its intended design.
From simple tweaks to ambitious experimentation
The modification journey began with a relatively modest upgrade. The team replaced the laptop’s stock thermal material with a 2.5mm thermal pad to improve heat transfer away from critical components. This initial adjustment delivered measurable results, with performance increasing by around 14% while temperatures dropped slightly.
Although the improvement was notable, the modders were not satisfied with incremental gains. Their goal quickly evolved into something far more ambitious: transforming the MacBook Neo into a system capable of sustaining significantly higher performance levels without overheating. This shift marked the transition from practical enhancement to experimental engineering.
Encouraged by the early success, the team decided to abandon conventional laptop cooling approaches altogether. Instead, they began designing a custom liquid-cooling system, typically reserved for desktop computers and high-end systems. This decision set the stage for a complex and highly unconventional modification process.
Building a custom water-cooling system
To implement liquid cooling, the modders created a bespoke copper water block that sits directly on the laptop’s processor. They also constructed an acrylic reservoir to hold the coolant, forming the core components of the system. The process proved challenging, with issues including difficult-to-machine copper, broken drill bits, and intricate threading.
The most drastic step was cutting a hole in the bottom of the MacBook Neo’s chassis. This irreversible modification allowed the cooling system to connect externally, effectively transforming the laptop into a hybrid device that resembled a desktop computer more than a portable computer.
The completed setup incorporated a small pump originally designed for smart watering systems, paired with a large power steering cooler repurposed as a radiator. Together, these components enabled continuous coolant circulation, dissipating heat far more effectively than the laptop’s original passive cooling design.
At this stage, the MacBook Neo had been fundamentally altered. Its portability and simplicity were sacrificed in favour of raw performance, turning it into a showcase of engineering creativity rather than a practical consumer device.
Performance gains and benchmark results
Despite its unconventional nature, the modification delivered substantial performance improvements. According to the modders’ results, the fully water-cooled MacBook Neo achieved a 21.2% increase in performance compared with its original configuration.
The gains were particularly evident in benchmarking tests. In the 3DMark Solar Bay Extreme benchmark, the modified device reportedly achieved a world record score for this model. This result highlights the extent to which thermal limitations had previously constrained the laptop’s capabilities.
Notably, the enhanced MacBook Neo was said to outperform the M1 MacBook Air in the same benchmark, demonstrating how effective cooling can unlock additional processing power even in lower-tier hardware. While such modifications are impractical for everyday users, they underline the importance of thermal design in modern computing devices.
The project ultimately serves as both a technical demonstration and a reminder of the trade-offs inherent in laptop design. While manufacturers prioritise portability, efficiency, and cost, these choices often limit performance under sustained workloads. By removing those constraints, the modders revealed the MacBook Neo’s hidden potential, albeit through a solution few would consider practical.
