【Honeywell PTM7950 High-Performance Phase Change Thermal Pad / Silicone Grease Set】 Compatible with GPU, CPU, SSD, M.2, Laptops, PS5, and Steam Deck Honeywell's PTM7950 is a phase change thermal pad with excellent thermal conductivity, boasting higher reliability and heat dissipation efficiency than conventional thermal paste. • Size: 40 x 80 x 0.25mm • Phase Change Temperature: 45°C • Thermal Conductivity: 8.5W/m・K • Low Thermal Impedance: <0.04℃・cm²/W (without shim) Employing new polymer PCM (Phase Change Material) technology, it achieves excellent adhesion and very low contact resistance even within the typical operating temperature range. It boasts high durability, withstanding a 1000-hour baking test at 150°C and T/C-B 1000 cycles. Includes high-conductivity silicone grease (8.5W/mK) Using it in conjunction with the thermal pad maximizes cooling performance.
