NOTE: Does NOT work with the stock fan shroud. I ended up drilling holes and mounting it on the outside of the stock shroud but I still had heat creep issues. So I finally printed the Hero Me fan duct (see pic) and the issues is solved. LOVE this fan. Plus now I have 3 backups. I have used this brand in the past and they tend to fail after about 4-5 months of heavy use but we'll see if this model is more durable.

I have used this brand in the past and they tend to fail after about 4-5 months of heavy use but we'll see if this model is more durable.
After several months, the fans (40x20 24v dual bearing) are doing great. With the stock Ender 3 V2 parts cooling fan, it was always on 100% to move enough air. With these fans on a dual Fang setup, I never have to set it above 15%, so they're MUCH quieter than stock.
Had to remove a star for the garbage insulation and brittle wires. If you're going to use them on the hot end you absolutely must reinforce any part of the wire that moves repetitively during prints, otherwise the insulation and wire will eventually fatigue and break. I had to use a combination of hot glue and heat shrink tubing to use as flexible stress relief.
-----------------------
First review:
Bought a 4 pack, and already two of them have had broken wires. Whatever they use for the insulation on the wires is brittle and garbage.
Will update if seller honors 24 month warranty.
They are quiet and have enough power to pull the air through the filter.
Top reviews from other countries
Ils ont un très bon débit d'air et ne fond pas de bruit.
Je recommande sans problème
here are the pros:
1- air flow is much much better that before.
2- the fan will start blowing air at 5% power compared to the stock part fan that does not start spinning until 10% power.
now the cons:
1- not any less noisy compared to stock fans.
