Flashforge Creator 3 Print head cover

I will replace the print head fan. the original one is very noisy.
Original is a 4010 and the original cover is very tie.
My new one is Fan/Ventilator 24V 1,4W 40x40x10mm 11,9m³/h 27dBA ; Sunon KDE2404PFV2-11AB

This design also fit a 4015 fan
I print this in PETG it's ok as all plastic part are far from very hot part
May be Polycarbonate would be better
