4 passes tends to mean each pass is done more quickly. Assuming the radiators are of similar size then the water will take roughly the same amount of time to flow through them (flowrate is uniform throughout the system). That means the water in the 4 pass has to move approximately 4 times as quickly as in the 2 pass. 4-pass tend to be higher restriction which impedes flow rates which is why 2- and 1-pass are favoured.

C/W = degrees celcius / watt. If you have a 180W heat source and a 0.17C/W cooler then the heat source will experience a 30.6C temperature rise over ambient.
