I read a book or series in the mid 1980's which featured:
- organic computers that had to be connected to a tap by the hacker so that the running water would cool them
- main character(s) injected with nano-chips (as children?) that gave them special (mental?) abilities
- high-tech spy gear included a cool-suit which absorbed body heat to elude thermal imaging cameras around the yard of a building, but had a limited usability because after a certain amount of time the heat-sinks would have to vent steam or else quickly cook the wearer.
Unsure if within the same series, but there was one character who stowed away on a spaceship which was travelling to one of the gas-giant planets in our Solar System (Jupiter or Saturn?) and within the gas giant whale-like intelligences were discovered.
