SU1225FD12M-RHP

Update: after setting a fan curve, these fans are near silent and performing very well. 5 stars. TL:DR: if you want decent priced addressable RGB fans, these are a good buy. I have a fuma 2 CPU cooler which I really love, so I figured I'd go back to scythe for some case fans. These fans look and feel premium. Pros: -RGB looks nice, can use JRGB headers to sync with mobo lights -price isn't bad -Move a fair amount of air Cons: -a bit noisy. Maxing out at just 1200 RPM, I expected these to be virtually silent, but they are not. Not terrible, but not great. -the 4-pin fan cable is really short. The pics show the RGB cable and the fan cable at the same length, but the RGB cable is significantly longer. Had to buy some extensions.

i picked up this 2,000rpm model to replace the 1200rpm pwm version that came with my fuma 2. i had swapped out the front fan that came with it with a noctua a12 and wanted to upgrade the center fan as well to semi-match rpm's and static pressure. but i wanted to keep the alternative air thing scythe has going on with the fuma 2. since i couldn't find any other fan that spin clockwise like the kaze flex does, and since scythe doesn't make this version as pwm, i went ahead and just bought this one. this fan at 2000rpm really puts out a lot of air and a solid amount of static pressure through my fuma 2. its a really nice upgrade over the 1200rpm version. it is loud at 2000rpm, much louder than my a12, but its not a motor noise. its just the sound of moving air. in terms of voltage control, my motherboard appears to have no issue controlling its rpm via voltage. i have it sit at 30% at 30c, and ramps up to 100% at 55c which is very rare. it mostly sits around 30-70%. but its definitely not as smooth in rpm switching like a pwm fan is. i really wish scythe made a pwm version of this fan. with how high it can run at, i don't know why they didn't. i was interested in picking up their 1800rpm kaze flex rgb pwm version, but i can't find it at all for sale here in NA. so this was the only option. i would still buy it again, but if scythe released a pwm version i would grab it.

I replaced the middle Kaze Flex 120mm 1200 RPM fan on my Sycthe Fuma 2 with this. Not much of an improvement but there was some and didn't notice a difference in noise so I kept it. But it works best as an exhaust fan where it was quieter than the Arctic P12 and slightly cooler. Given this is an airflow fan and not high static pressure fan that's no surprise. So use it for it's intended purposes and it's a great fan up there with Noctua at a cheaper price. Highly recommended.

Scythe is practically the only company that makes fans that rotate the opposite direction of everyone else, which is the only way to get any actual additional airflow by stacking fans. It's still only a 15-25% increase over a single fan (depending on fan speeds and pressures), but if that's what you need, this is the fan for you. It's quiet, inexpensive, and well-made. It's not super high-performance, but there are tons of fans out there that are (I recommend Be Quiet! fans) and this is a good way to eke out a little more airflow from one of those.

You should know going in that a near constant speed 2000 RPM fan is going to be loud, not for the fan itself as much as the sound of air. The fan itself is surprisingly quiet, between the padded contact points and quality of construction, there's no whine or rattling to be found. That being said this is one of the most underrated case fans I have ever used. Have a mediocre case that was in desperate need of help reducing internal and component temperatures. This thing alone has decreased CPU and GPU temps significantly operating as a rear case exhaust fan. I'm pretty blown away (pun definitely intended). If you need a fan that is easier on the ears I would say some of their PWM models are likely to be winners as well, or potentially some of their lower RPM DC variants. I haven't tested it in a static-pressure dependent position but it seems to be highly rated on that front as well (confined intake and/or radiator applications). If you need a 3-pin fan that moves some serious air and do not care about excess noise, this is your fan, bar absolutely none.

One of the preinstalled fans in my case developed an extremely loud and obnoxious buzzing problem. Literally I could hear it from the other side of my house. No cleaning/dusting/adjusting that I could figure out helped at all. So after finding out from the manufacturer how said fan was meant to be accessed, I got this Scythe to replace the complaining fan. It was ridiculously easy to install (even the box was easy to open, unlike 98% of the products sold on Amazon) and it seems to be working perfectly. No more constant buzzing, now I can use my theater/gaming PC again without cringing... great product.

I am really impressed with the quietness of these fans. I purchased two 120mm fans and mounted them side by side inside a full size tower ATX case. There was hardly any noticeable additional fan noise created by these fans. There is a rubberized material in the four mounting corners which I believe is to help reduce vibration. I built my own PC and have 4 SATA hard drives installed plus I added a video card that had a large heat sink but no fan. My case allowed me to install one fan right over the video card and the other resides nearly over the processor fan so air flow is no longer a concern. Just for reference, the fan does not show air flow direction. The air flows from the sticker side towards the exposed fan blade side.

THESE THINGS ARE BETTER THAN MY NOCTUA FANS O_O

I'm surprised because a lot of the reviews say no motor noise, but all three that I purchased make a distinctive motor whirring noise. It's high pitched and very loud. I'm even using a scythe fan controller and the motor creates noise no matter how low I set the fan speed. Disappointed to say the least.

Funcionó de acuerdo a lo esperado, producto de calidad y cumple exactamente con lo que promete. Lástima que la marca no tenga en 80mm

静音タイプのPCケースファンで、羽根枚数が多く風量も十分に稼ぎながら それでいて静音なFANという、かなり欲張りな商品です。 風量は厚みのある(25mm厚)のファン同士で比べると必要十分な風量を稼ぎ出しています。 静音性は様々なタイプが出ているので全てを比べたわけでは無いのですが、 羽根枚数を増やした低速回転モデルの中では、高回転時もソコソコ静かで良いと思います。 オススメできます。

Scythe Kaze Flex 120 mm der scythe kaze flex werkelt bei mir als zweit cpu lüfter in einem push pull modus... der mitgelieferte lüfter meines mugen 5 rev b ist zu dem nachgekauften identisch, läuft aber etwas langsamer orginal mugen lüfter rpm 348-1118... nachgekaufter 370-1199 rpm... hersteller gibt eine toleranz von -+ 10% an beide laufen bei mir aktuell mit leisen 650 rpm -+25 rmp und halten dabei die cpu einen amd ryzen 5 3600 auf rund 50°C bei teillast bis 92% cpu auslastung ... im idle fällt die cpu temperatur auf unter 40°C... r23 cinebench bleibt die temperatur unter 70°C... 70°C wären bei meiner angepassten lüfterkurve 60% pwm also rund 800 rpm, was immer noch leise ist... nur der per y stecker mitangeschlossene 140mm deckellüfter wird dann etwas höhrbar, aber immer noch relativ angenehm leise... den Scythe Kaze Flex 120 mm würde ich als cpu lüfter erneut kaufen falls nötig
