Custom Water-Cooled PS3 Gets a 50% Performance Boost, Running Gran Turismo 6 at 60FPS - Yanko Design
"Zac Builds explored that alternate timeline by engineering a water-cooled, overclocked variant that pushes a carefully selected CECH2501B model to its absolute limits. Through precision engineering, advanced materials, and custom firmware, this modified console achieves what Sony left on the table: locked 60fps in Gran Turismo 6 and dramatically smoother performance across PlayStation 3's library. The whole project started from a simple observation: modern hardware comes aggressively tuned from the factory, leaving maybe 3-10% performance on the table if you're lucky."
"Those integrated heat spreaders covering the CPU and GPU use thermal interface material that dries out over time, turning your console into a space heater. The GPU's spreader was literally glued down, requiring hot air and steady nerves to pry off without destroying the chip. The CPU spreader used a silicone ring that needed careful knife work to remove. One wrong move and you've got an expensive paperweight."
An overclocked CECH2501B PlayStation 3 was modified with water cooling, upgraded thermal interfaces, and custom firmware to maximize performance. The 45nm CPU and 40nm GPU in the CECH2501B provide thermal headroom and remain hackable, unlike later super slim models. Dried factory thermal material was removed, the GPU spreader required careful prying, and the CPU spreader used a silicone ring. PTM7950 thermal compound was applied and high-temperature RTV silicone sealed components for longevity. The result is stable locked 60fps in Gran Turismo 6 and notably smoother framerates across many PS3 titles.
