Personally , I spend a disgusting amount of time on the wiki . That ' s how I remember everything . <| sep |> I have what I think is a loud T 430 . As I understand it , the fan assembly came from multiple manufacturers , and in some models an inferior , louder fan is used . The internet tells me the quiet fan produced was made by Delta Electronics . Is this the same reason you replaced yours ? This could also possibly be the case for the T 420 as well . <| sep |> there is a special place in hell for people like her . <| sep |> I hope you are enjoying the watch , but to me it isn ' t anything like any other Patek . When I think Patek , I think of elegant , classy watches . This one doesn ' t do it for me . Anyway , I genuinely hope you enjoy it !
