ok another question :s , can i place the pump (mcp655) vertically without doing damage to it? i mean placing it on its side or on its back?
and also will the pump be efficient to run this loop:
MCR320 -> CPU -> MCR120 -> Mosfets -> NB -> SB -> MCP655?
or should i run the third loop on its own? because i don't want to add a 3rd res and pump to the case it would be too crowded

thanks again guys
