Connector with wire for the fan on the third link is only available from 1000 pieces. I don’t need so many :). Gouwa, you can give me a other link to connector for fan VIM2 ?
You planning to release the adapter from the fan connector on the Board VIM2, on standard versions of the 2PIN connectors that are commonly used on fans. I think this adapter at low cost of production, many users will want to buy the 3-5$ for the VIM2.
By the way, if you add a set of fan for VIM-1, with this adapter, you can issue one set of fan for all produced now models VIM. You can take as a basis the existing option kit fan for VIM-1, add an adapter to the VIM2, radiator (in my tests is enough 20x20x6), and can produce a new universal kit for all VIM.
