Phanteks (PH-F120T30_BG_3P) T30-120 Fan Triple-Pack, Premium high-Performance Fan, Excellent Sound Quality, 4-pin PWM, Multiple Fan RPM Modes, Black/Grey

TL;DR: meaningful only for situations where the Noctua NF-A12x25 is just not enough (e.g. hight TDP CPU in a computer case without enough space fort a full size cooler) and where there is an extra 5mm of space to accommodate the 30mm thickness.

Love these things. My CPU would throttle before, but once I exchanged the radiator fans, it was ice cold. The volume of these fans are good too.

These fans offer excellent performance at all noise levels and came with the screws I needed to use them as case and rad fans. I like the flexibility to ramp them up to 3000 rpm if I want, or just get better performance at lower RPMs. I swapped out stock radiator fans on my radiator and saw my GPU die temps drop, and overall my system temperatures are down due to increased airflow. Id definitely recommend these.

The Fans itself are pretty good. Impressive as many have mentioned before. I used it on my new Arctic Liquid Freezer II 360, initially intending for Push-Pull configuration with my first foreray into AIOs, though it turned out all I could do is use a push or pull configuration because the 90 mm clearance on my Lian Li O11 Dynamic was not only over by a bit when having 2 sets of these, the cooler itself was 38 mm depth, thus needing 98 mm to clear. For me, that wasnt so bad until realizing that I had both the thick CPU Power cords and the I/O Shield in the way of slotting the back part. Thus, I COULD do 5 fans, though Im not sure how much of a difference that would make having 1 section getting only pull.

If they fit your case, need tons of airflow and dont mind some noise, you will be very happy with these fans.

These fans are powerful, quiet, and very efficient. I just installed them on 2 1080mm radiators which take 9 fans each. Super easy to connect with the built in daisy chain. Amazingly I am able to run 9 fans at full power in performance mode (2000rpm) daisy chained on a single motherboard header. In Hybrid mode you could chain 20 of them together on a single 1 amp header (0.05 amps each).

These Phanteks (PH-F120T30_BG_3P) T30-120 Fans work really well. They are the best fans I have used. They push a lot of air and is still very quiet. Price was somewhat higher than I wanted to pay but its a supply and demand issue and I needed to get the best cooling solution I can get.

These fans are great as intake case fans or fir a radiator. While they might be a bit loud at 3000rpm, its not nearly the noise level of the indistrial 3000rpm noctua fan. Static pressure is great thanks to the thicker fan blades and I expect they will last quite some time with their magnetic levitation bearing.

having purchased in total nine of these fans for two systems, i needed to return three as pwm settings were being ignored and regardless of switch settings the fans always wanted to use the 3000rpm profile. Wanted to return the others also however buyer must pay to return and then accept phanteks will also deduct 15% !!!!!

I built a SFF case using the DAN A4 H2O case.
