I am not 100% sure, but I think it have been the replacement impeller that has been the new stiffer one...
I think we all must be more clere to what we have bought.
I have 2 of the new "Replacement Blades & Carrier for 12 Blade High-Performance 90mm EDF Ducted Fan Unit" and both of them weights 51 grams.
So you bought just the replacement fan that comes with the washers... I bought the "whole unit" which is the fan and shroud and mine was the old 45g version. If the fan didn't take out the shroud when mine let go I'd buy what you bought.
