1. A method for two-phase immersion cooling, the method comprising:
unsealing an immersion tank used in immersion cooling of a computing device, the immersion tank at least partially filled with dielectric working fluid, the computing device submerged in the dielectric working fluid;
creating a negative pressure at a vapor collection point, wherein the vapor collection point is not in fluid communication with an interior portion of the immersion tank when the immersion tank is sealed; and
when the immersion tank is unsealed, collecting, at the vapor collection point, working fluid vapor from the dielectric working fluid.
