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

EDIT: Its been long enough, they absolutely need these in 140mm variants!

These fans are really nice, they push air very well without having to sound like a jet engine going in your pc. I use these as radiator fans in my Lian Li Dan A4 case which is a VERY snug fit but works really good by pushing all the air out. Comes with everything youd need, screws and extensions, Also daisy chained braided cables which is nice.

Perfect and quiet even a 2000rpm, at max its louder but not like other fans.

I just finished a new rig, and - after making several mistakes (Corsair…), I ended up purchasing this for an external radiator I set up.

If you like the Noctua NF-A12x25 performance and quietness then these take both to a new level. Very quiet with more CFM but can also deliver more top end CFM of course at the cost of higher db. No regrets!

Tried it today, at 1600rpm moves more air than all the other fans I own... But because I work on a dead silent place its not good for me... Past 1600rpm, I can hear the motor, and its a penetrating sound, the mini itx case is 24 away from me it disturbs me after a while... I will use it on my gaming Atx Tower Rig, but for my office no.... Just for information, I have tried fans like XPG PRO GT2150, Noctua a12x25, Be Quiet Silent Wings 4 and Arctic P12 Max, and between 1600 and 1850rpm, all I can hear is the air moving... But with these ones I can hear the motor... Great fan, As a technician, I highly recommend it, static preassure and airflow are above expectations... Great fans over all

One caveat - they are rather hard to screw mount due to glass fiber reinforced material on the housing.

In my 25+ years of pc building, this is by far the best fan Ive ever used. I removed the stock fans from a Thermalright Peerless Assassin cooler and replaced both of them with one of these in the middle. Temps dropped by 3-4 degrees celsius and it is super quiet. Moves a ton of air with high static pressure. Perfect fan other than the high price.

If youre thinking of replacing NH-D15S stock fan with these, they fit just fine with the included NH-D15S clips.

If anyone knows something about how crucial air flow is, ask the homies with the tiny computers.
