This thermal grease stencil tool is used to retrofit the S19 hash board heatsinks. It covers the S19 hash board except for the ASIC chip so that it can evenly spread the thermal grease without damaging other small electronic components around it. Improve the success rate of installing and upgrading heat sinks, reduce maintenance costs, and increase the coverage of silicone grease. It is a common spare for using modified radiators.

How to use: Put the heat sink in the template, brush the thermal grease evenly, and then cover the heat sink with the grease on the hash board.
