OK, so I've tried pretty much every fan mod that's on here for the creality/ender series (I have the Ender 3) and I've had issues with all of them. Either the fit isn't right or the airflow isn't as good as it needs to be. I've also had issues with certain fan mods actually catching on parts of the prints if it's blobbed up ever so slightly or some of the ooz sticks to them, filling my entire hotend with extrusion as they essentially act as giant cups for the extrusion to fill.
I've only tried a few prints with this one so far, and I only have it made in PLA, but so far it's hands down, second to none, the best option I've come across. Not just because it's performed so far, but the design, ease of use and the fact that it uses all stock parts. One thing I want to say though is if you're going to print this, make sure you compensate for the shrinkage of whatever material you print with by scaling it up a percent or two when slicing.That said, the only thing I had to do (since I forgot) was to cut out just over half a millimeter to get the top fan to click in place with an exactoknife. Everything else fit as if factory made. I can't recommend this enough from my initial impressions, and this isn't likely to ever be taken off unless I reprint it in PETG.
Edit: I've now done many prints, including printing at 230C for TPU and it's still working flawlessly. I have around 30-40 hours of printing with it now, and ~8 of those are printing TPU. The PLA is still holding up, so I don't think this will be a problem for anything that doesn't require an enclosure or is something super exotic where you need to be around 300C to print.
