Refit T17 hash board tool thermal paste stencil This thermal paste stencil tool is used to refit the heat sink of the T17 hash board. Use this tool to cover the T17 hash board without covering the ASIC BM1397 chips.

The success rate of installing upgrading heat sinks is improved, the maintenance cost is reduced, and the coverage rate of silicone grease is improved. It is a common spare part for using refit heat sinks.
