. . . . .
far too simplistic a question to assess the impact of fans and tubing size

start with noise:
list all sources and levels
identify those which can be altered
so where does WCing fit ?
the fan on the hsf went to the rad - presumably bigger and slower making less noise
but a pump is added, how much noise ?
-> note that the pump size IS related to the tubing size, so for a low noise WCing solution the 1st choice is the pump - which if based on noise will be small
- so the line size is small

do you understand that a small pump and fat tubes are incompatible ?

so now you have small tubing and a small pump, and large tubing with a large pump
- now one could put a big pump on the small tubing, but to what purpose ?

now the rad size can be addressed, for Swiftech this is predicated on installation convenience, you would consider noise
-> the only low noise solution is a thin rad, the bigger the better
-> a thick rad with a low noise fan will be outperformed by a thin rad with the same fan

so the only true low noise solution uses a silent pump, which requires smaller tubing

ah, but how big can the small lines be ?
well, again it depends on the pump - but not less than 8mm ID for a low noise Swiftech kit
