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

Great quiet fans that are in use with my radiators. It moves a lot of air and is comparable to the cost of the Noctuas. I have 3 240 48mm HeatKiller rads using these and the water temps at idle is 28 degrees Celsius. Ambient temp is 24 degrees Celsius. My 5900x is sitting at 38.5 and 3080ti at 28.5. Overall, I think it’s an upgrade from the Noctuas.

Perfect for applications that need silence and high airflow. Will be purchasing a few hundred more for my computing farm.

Good and quiet, and objectively performs better than Noctua fans with a radiator.

I bought a couple of these to replace the stock fans on my Gigabyte rtx 3080 ti xtreme waterforce, these run at minimun of 30% (bios restriction) and even at these speed the stock fans are really loud, with the Phanteks T30 I get 7C degrees less on GPU core and silent fans. Very satisfied with this purchase

Wow to loud and my old fans did the same airflow

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.

i used these fans to install on a gpu. its slightly over 4 slots now lol. performs way better than Noctua nf-a12s did. the only problem i had is with the plastic fan power connector/jumper right next to fan shroud. it gets in the way around tight places. i made it work though. i really want to use these on an cpu air cooler. you cant since they are 30mm. the thin metal clamping piece other cooler manufactures give you only fit the 25mm fans. i hope somebody creates those metal clips that will work. moves a ton of air. i cant wait for a 140mm version. best 120mm fans i know of.

Absolutely the best fan due to its sheer volume of air movement alone it passively is quieter and still has incredible performance and even cranking it up all the way it really isnt that loud.

Chart-topping performance for watercooling

I read and saw many reviews and was eager to try these out. However, I am unable to complete installation. These fans are 30mm thick rather than the standard 25. Many cases are designed with 25mm fans in mind so you may find it difficult to use these in the same configurations you would use typical fans. My main issue right now is that the screws that come with these fans do not fit into my bits power radiators - these screws are too skinny. So, I either replace my radiator, send back these fans or try and get the correct size and length screws from a hardware store.
