Great budget high pressure fan
A good budget option, especially if you can find it on sale, great for use on radiators if you are water cooling. Significantly more powerful than the dirt cheap generic ones, provides good airflow, strong pressure, with minimal noise. This replaced a cheap Chinese (I think thermaltake or thermalright?) exhaust on a 120mm radiator and it did make a small but noticeable improvement to my pc temps. It seems to be well built, with the plastic seeming strong, stiff but not brittle like cheaper alternatives. In terms of design it’s basically the same as every other fan, easy enough to install, the pwm and aRGB leads are a decent length which always helps - although I still needed to use extenders, this did make cable management easier. The PWM and RGB both work the same as every other fan I have, worked on both my motherboard headers and hubs, no software issues in terms of controlling speed and colour.This is for you if:- You only need one fan and you want RGB. I’d primarily recommend it for an intake or use on a radiator for watercooling due to the high static pressure.Maybe consider other options if:- you require multiple fans then you will often find better value in other products that come in multipacks, especially the Arctic P12.- you don’t intend to use the RGB, there are far better non-RGB options at this price point.At the end of the day I give it 5 stars as it’s a great product at a reasonable price and has no notable problems, however this comes with the caveat that you should shop around first as there will often be better value out there depending on your individual requirements.

Worth the price for high end case fans that look great
I sit right next to my rig so I wanted high end cooling performance from my case fans with low noise and I can say these fans check that box in a big way.I set my fan curve in the bios so they run at 33% constant (silent at my seating distance of right next to the box) until the CPU hits 65 degrees and in most games 33% speed is enough so that the CPU never gets hot enough for the fans to spin up! Big win.When I put on a proper stress test and the fans do spin up the temps drop quickly and under sustained 100% load I have never seen the CPU or graphics card go above 70 degrees.The fans ARGB looks fantastic and is dimmable, the attached photo is from setting "Music" mode in MSI mystic light where the light pulses in time with the music.Your milage may vary depending on setup but I have found these to be excellent fans.

Good quality rub fan
Coolermaster fan, works as you expect quite and offers good aero performance.

Fantastic
The media could not be loaded. After going for a full Noctua fan system it was very dark.I still kept majority of my Noctua but needed something else with RGB and most importantly good performance and low noise.Replaced my Kraken fans with these and the exhaust case fan and they are very good.Lights are stunning and very low noise, I’m glad I’ve picked these as PC looks so much better now

Does the job
Used to replace 120x15 fan on Id-cooling IS-55,which stock is still a great CPU cooler. The case I was using was a Goodisory (SKTC) A02 which is a lovely case that takes LP GPU(without riser) but airflow is not very good. First tried Morbius OC in standard (middle mode) that worked fine but a little noisy,so tried on lower setting and much quieter and still CPU at sensible temps. It's handy to have fan speed toggle on cable

Worth buying on offer.
Outperforms more expensive Phanteks T30 flagship fan at lower RPM in noise & performance according to video reviews i bought enough to kit out 2 x cooler master NR200's. Lifetime warranty too.Update: i switched out 4x coolermaster sickleflow 120's (2x case 2x on Hyper 212 evo V2 cooler) in favour of 3x mobius OC (2x case and 1x on Hyper 212) and my idle temps dropped 5-6 degrees so clearly moving a lot more air. Idle temp on my delidded 9th gen 9700k @ 4.8ghz is now just 28'c

Amazing fans with a few quirks
First of all these fans are very quiet, secondly the RGB is very good. Once installed they are top tier!Secondly the installing should be easy but the cables are bit short, I had to use PWM extension cables to reach my fan hub. The ARGB connector is daisy chained which is handy but the tail to connect back to your motherboard or another ARGB device is way to short.Considering the price I would have liked to see some longer cables or extensions in the box. A three pack with the last tail extensions would be great.Even with the short cable issue I would still recommend the product.
