With Single-phase Liquid Immersion Cooling (SLIC) technology, temperature regulation is done by either increasing the amount of cooling surface area, or by increasing the efficiency of the cooler (most often by having thermostatically-controlled fans). Increasing the fluid flowrate helps only if the flowrate is too low to efficiently remove heat from the hot components; once it's flowing fast enough to do that, then further flowrate increases won't help.
Increasing the fluid volume won't help the system run cooler, but it will help the system to be easier to maintain at a steady temperature when there are fluctuations in other parameters. Having too little fluid in a system makes the system less stable and run on a "knife edge".
