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.

Best fan I ever bought for my pc build. The original fan I bought was high end and Quiet “ Noctua” but it a high pitch sounds at speed 700 to 1200 RPM and wired Harmonics. The Phanteks T30 fix all my issues almost have no noise

Ive done a lot of research on fans over the last few years as I have tried to make my PC as quiet and cool as possible. Until someone else releases a 30mm 3000+ rpm fan, this will be the champ. I have a powerful pc, custom water cooling and these fans have been the biggest improvement so far. They are quieter than my D5 water pump and keep my 13700K and RTX 3080 cool with a 360mm radiator. They move so much air at lower RPMs, with so little noise. Yes, 3000RPM is pretty noisy but also unnecessary. I cant imagine who would need 3000RPM out of these fans. Having the switch to limit the fan speed is pretty handy too. Love that you can daisy chain, just make sure you dont overwhelm your fan header. If you can afford it, its worth it. The performance/noise is tough to beat.

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

If you can, install this first

I have been battling heat for awhile. I have used many fans including: Corsair, Antec, no names, and Noctua. These are by far the best! CPU temp dropped 10C and VRM by 15C, They fit well in my Thermaltake case despite being 5mm thicker. They are pricey, but they finally get the job done. Update: I just installed one on my Corsair Hydro H-60, the temperature dropped by another 4C. i9-11900K idles at 28C, SSD temps. also dropped.

Best fans out there if you have the space for it.

These fans are great! They move tons of air, especially through a radiator. I have a 240mm EKWB AIO and these are keeping CPU cooler than the fans that came with it! Just be careful, as other reviews have stated, these fans are quite thick, 30mm thick compared to the standard 25mm think can be quite a difference; however, if you can fit them, they are the best you can buy.

Wow to loud and my old fans did the same airflow

Using as exhaust, it throws a ton of air back. Should replace my AIO fans with three like these.
