1. High quality material: Made of with a high thermal conductivity of 401W/(m.k), chemically polished to prevent burrs and short circuits. 2. Comes with thermal conductive silicon wafers: Thermal conductive silicone grease is soft and resilient, paired with high-performance 5W/m.K thermal conductive silicon wafers, which can tightly fit the of electronic devices and fill in space in hard disk particles, keeping the heat dissipation fins at the same height, achieving rapid heat dissipation and extending the lifespan of the hard disk. 3. : Accurate size calculation to prevent installation deviation and short circuit, suitable for the installation space of laptops. 4. Usage: TN42 is suitable for M.2 2242 solid-state drives, does not support mSATA disks, but supports B Key and M Key disks. 5. : After multiple grinding and milling processes, the undergoes oxidation resistance treatment, which does not rust or oxidize, making it more than ordinary copper sheets. Combined with high-performance thermal conductive silicon wafers, it has better heat dissipation and is not easy to leave fingerprints. The will not oxidize and darken after long-term use.
