Hi All I'm just looking at some fans and just wondering are branded fans just marketing hype if most factors are using the same base for comparison ?? EG: Generic: https://www.ebay.com.au/itm/265249361067?hash=item3dc2180cab:g:fy4AAOSwAdlhBlsG&frcectupt=true Brand: https://www.pccasegear.com/products/54753/arctic-p12-pwm-pst-120mm-pressure-optimised-fan-5-pack So I see that the Branded ones use better bearings (longer lasting / more quiet) ... but the Generic pumps out 18.2 CFM more (+32%) @ $10 cheaper (-28%) Am I missing anything here in my thinking (from a functionality POV) ??? Thoughts ??
