Do you not need a more powerful pump to get the water round?
Most radiators are not very restrictive.

Yea rads are not that restrictive. I was surprised when flushing it how easy flow can pass through. It's just cpu and gpu blocks which seem to restrict flow. obviously more blocks you have will increase pressure slightly but nothing compared to adding a second gpu and block.Most radiators are not very restrictive.
That is true, but the sound of fans doesn't increase in a linear fashion. For example 4 fans aren't twice as loud as 2 fans. So it's very possible that there wouldn't be a perceivable difference in volume going from 8 go 12 fans if they're well performing at low RPM.Of course, I see your point, but fans only run so slow, and it's not like you can keep ratcheting fan speed down relative to quantity of fans... eventually you hit a bottom speed limit (400-600RPM typically, depending on the fan in question, some will be higher). For example, for fans running at 600RPM, x12 of them are going to emit more noise than x8. That's just obvious, they aren't totally silent. How much noise will depend on the fan of course, and it may be negligible in some instances to the point that it isn't really noticeable. Every set-up will be different. Ultimately though, it's pointless beyond a certain number, especially when you factor in cost/performance.

This is a handy calculator for working out noise levels when adding more sources. The more you add of the same noise level the less overall effect it has.

Interesting. Less effect, but that obviously doesn't mean 20 fans would be quieter than 10.
