The Halos will somewhat constrict the fan's airflow a bit, and basically you'd get the same constriction for the Silverstone fan ARGB ring. I'm not sure how much difference it makes, or whether it's more/less if the light ring is mounted on intake or exhaust side. I got both of them to try with my Noctuas, but eventually decided to use them elsewhere and leave my Noctuas bare and unrestricted.
(The Halos will probably give the better fan lighting effect than the Silverstones, but what I did was mount the Silverstone rings on their own as overhead lighting on the "roof" of my case which works nice.)
