Best value to quality fans I know of
Great fans, quiet and very nice performance, though one did arrive with broken RGB. I have another 3 120mm versions installed in another PC and never had any issues with those, and the replacement fan works fine so I still feel good recommending these to anybody

Best fan's I ever had
Amazing fan's, a little expensive but the build quality makes up for that. Noise is okay and it kicks out alot of air. PC running 5°C cooler now after replacing my old cheap fans. RGB look's amazing. 10/10

Perfect RGB fans and great service. Will use again.
Fans are great and make a big difference in air circulation and visual appearance. No negative comments on this product or it’s dispatch and delivery. Will be ordering another pack of three fans next week. Great service.

brilliant colours through the fans and performance.
I decided to go for a full cooler master cooling solution and purchased these MF120 fans, looking at the numbers, they had decent numbers on the fan. they are easy to install and the instructions are easy enough to follow, I've ended up using the AIO in this setup too so plugged them into the controller from that set instead of the one that is included in this boxset. the fans look lovely, the RGB elements can be seen on all sides, what is nice for the aesthetics, ive tried to capture that in the images, my only issue is with either my wiring or a software hiccup, the colours arent staying what i set but that will be sorted with time. overall I find the noise levels adequate without being distracting, the colours are brilliant and so far keeping the system cool, i happy with the purchase.

Great Case Fans
Fantastic fan in Lian Li Lancool 216 RGB. Lian Li don't make matching case fans for their factory front fans, so I found these and think they work great. Not sure why, but the 120mm fan on my CPU cooler has the RGB going in reverse to the other 3, but still great fans and really pleased with my purchase.

Easy to install!
Dont believe people who miserably failed to simply install the fans into motherboard argb header. Always read the manual of your motherboard and this argb fan as it will save you a lot of time than watching youtube tutorials or googling it.

Very good
Very good fans but you can get them cheaper else where. £50 is what they are being sold for but overclockers are way cheaper but you have to wait a couple of days but all in all they are good
