The blower fan works great. It's not a true drop in replacement because the connector on it is the wrong sex, so needs splicing. I'm not sure if it's male and need to be female or the other way around, but either way - some "sex replacement surgery" is required. Other than that - works great, and is much better then the stock fan in every way imaginable (quieter and blows more air etc).
The heatsink fan is very quiet. I'm not sure if it's quieter then the Noctua. The only place i used these smal 40x10 Noctua's so far has been as a replacement for stock fans on the x570 motherboards. I opened up one of my cases just now to hear how it compares noise wise to the Winsinn, and to my human ear i cannot tell the difference.
Anyway, here is the pack i used - https://www.amazon.com/gp/product/B07R97ZSF6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
