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

Product does what it says. I had a 3000rpm fan before this for my heatsink, but it was quite noisey, so after looking at reviews I came to the conclusion this was the best 2000rpm fan out there, perhaps even better than Noctua. It may run 1-2 C hotter than my 3000rpm fan, on max temperatures, but the averages are around the same, however it is for sure quieter than my 3000rpm fan, which is the main reason I purchased it. Great product. Yes - there is a 3000rpm mode for this fan too, but I prefer to keep it quieter for now. Looking at some reviews online it sounded like 3000rpm mode was quite loud.

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

This is the best 120mm fan on the market - not much else to say.

These fans rock, just be ready to muscle in the screws.

The 20% added thickness how to make these fans one of the best there is I replace the best noctua fans with these. The fact that you can daisychain them helps with wiring.

The noctua fan I wanted was out of stock so I looked for alternatives and the t30 was one of the top results and I have no regrets in buying it. This thing is solid and pushes a ton of air.

Fans go burrrrrr

Using this in my ThermalTake the tower 100. The top fan area has about 40mm of space for a fan so I wanted to try and fill it up more with a thicker fan. I run this on a 60mm thick EK radiator and it pulls the air through like a champ. Deff recommend.

Moves a ton of air and is very quiet below about 1600 RPM. At 3000 RPM they move a metric ton of air, its nice to have the cooling headroom if needed, their loudness will tell me my rads need cleaning lol.

These replaced my 3 arctic p12 pwm pst on my black ice nemesis gts 360 radiator and provided a significant improvement. At 1000 rpm the fans are barely audible but in a pleasant tone and feel like they provide +5c difference.
