PTM7950 by CSGR is a premium phase change thermal pad designed to maximize heat dissipation and ensure optimal cooling for your electronic devices. Measuring 40x40x0.25mm, this advanced thermal pad features exceptional thermal conductivity at 8.5 W/m.K*, effectively managing heat transfer between your CPU, GPU, and heatsink. Our PTM7950 undergoes a unique phase change at 45°C, transitioning from a solid to a liquid state during operation. This property allows it to seamlessly fill any gaps and provide consistent thermal contact. When combined with our K5 PRO thermal putty, which remains viscous and effective even if the heatsink shifts slightly, this duo ensures that all thermal interfaces are perfectly filled, maintaining optimal cooling performance. The PTM7950 by CSGR is designed for durability, withstanding temperatures up to 150°C and enduring 1000 thermal cycles without compromising its performance. This makes it a reliable choice for high-performance applications where efficiency and long-term reliability are essential. For the best thermal management, the PTM7950 by CSGR, in conjunction with K5 PRO, is highly recommended by enthusiasts and experts alike. This combination is celebrated across forums and review platforms for delivering exceptional cooling results for gaming consoles, high-end PCs, and other demanding electronic devices. *Computer Systems materials science laboratory testing: Method using a comparative technique (P.
