Fantastic fan and pretty good value.

Pros: Great airflow Low noise Very smooth Good on radiators and dust filters Fairly inexpensive Inoffensive color scheme No bearing or motor click Pwm and dc are both smooth
Cons: No rubber grommets or mounts No included LN or ULN adapter I only bought one
Overall Review: I plan to purchase another two of these eventually and make them my main fans but for now I have two corsair sp120 qe's as my radiator fans and this is serving as my intake onto my cpu. It does excellently against flow restrictions but if you have it in open air, it's pretty much silent at full speed. The pwm control is fantastic and it gets down to about 400rpm like it's supposed to. It performs pretty much on par with Corsair's sp120 qe but at full speed it has a more spread out and less noticeable sound signature and at low speeds it pushes a bit more air. Both are excellent on a radiator and perform great as intakes with or without restriction. What really sets this fan apart which I wasn't expecting, though I probably should have heeded everyone else's regard for Noctua, is how polished of a fan this is. It's using Noctua's last generation bearing though you wouldn't know it because it is incredibly smooth with zero vibration and the blades are wonderfully balanced and centered with it doing no blade wobble or anything. Their "smooth ic" for pwm is super excellent. Corsair's fans are excellent but they vibrate a little bit and at lower speeds they click a little bit. these are perfectly silent at low speeds and there is no clicking or vibration. Tbh they don't even need the anti vibration mounts. Another thing is the magnet that helps stabilize the bearing is super strong. If i put the fan on some steel on my case, it will stick to it while it's sliding down. My corsairs don't do that at all and neither do any of my other fans besides my fractal design venturi hp12 but their magnet is considerably weaker. I now understand noctuas hype. They're fantastic fans and for $14ish dollars, they are totally worth it. Especially since they are grey instead of brown and beige. Great buy and will be buying more noctua from now on.
Probably a just a dud.

Pros: Looks good, good value, pretty thin, comes with am4 support.
Cons: Sounded like it wasn't filled properly, came with a few bent fins even though everything was packaged excellently, fan vibrates like crazy, cooled slightly worse than stock wraith spire, tubing a little short somewhat difficult to mount on am4.
Overall Review: It was probably only my unit but it gurgled constantly like it wasn't filled properly and the fan was super loud but not due to its 2000 rpm blade, it seemed unbalanced and vibrated like crazy. The packaging looked excellent and everything looked pristine except a couple of fins were bent. Probably due to the filling part, it cooled worse than my stock wraith spire cooler. On the plus side it's only 25mm thick so it fits most places but in a Silverstone rvz03 the tubing was barely, barely long enough to reach to my cpu so placement can be key. Another positive is that the pump looks surprisingly good. While I'm glad it came with am4 support, I wish they would give it a proper mount like they did for am3+ and lga 115x/2011. The clips were incredibly hard to get over the brackets on the board and to remove the cooler I had to unscrew the brackets from the board.
Simply excellent

Pros: Looks great, great price, great overclocker, works well on Ryzen.
Cons: I only have two ram slots to put these into.
Overall Review: I've had good luck with team ram overclocking well in the past so I decided to pay the $5 more for their rgb kit and it did not disappoint. I was able to get it up to 3200MHz on a Gigabyte ab350n board at 1.25v at stock xmp timings. The rgb looks fantastic and I didn't even bother syncing it with Gigabyte fusion, which it does work with by the way, since the "force flow" looks so good. 10/10 would recommend spending the extra 6.25% to get the great looking rgb.
Mostly great

Pros: Quiet, works well as a static pressure fan, feels high quality, cost effective.
Cons: Hub is a little big but good trade off. I worry about the fan vibration, which it seems to have a fair bit of, making extra noise once I finally eliminate my cpu cooler noise.
Overall Review: Especially if you can find it on sale for around $10 then it's a steal since it performs pretty similarly to Noctua's lineup and I've heard that they're a small bit quieter than the f12's. I was able to pick up two of these for the price of one f12 so personally I'd take that value over a degree or two improvement at the cost of minor amounts of noise most days.
