💡 How to pick case fans
What to look for:
  • 120mm most common, 140mm moves more air quieter
  • Higher CFM = more airflow, higher dBA = more noise
  • Static pressure fans for radiators, airflow fans for cases
💰 Two intake + one exhaust is a solid baseline for positive pressure

★★★★★Quiet and Cool
I bought these to go in my NZXT H9 Flow case and replace the stock case fans (3wire) with these PWM 4 wire fans, they offer superior control over the normal 3 pin. This keeps my case cool and quiet with the proper tune. I do near hear any rubbing or vibration from these so they should be well balanced. Use the Qtuning in the BIOS or any smart fan control that is available and switch the fans to PWM in the bios to properly use these. My temps are low on high end stuff and fan speeds stay minimal. Absolutely functions perfect in my case and settings. Keys to quiet: Bigger fans offer more flow at lower RPM = lower noise. More fans = more flow allowing lower RPM of all fans. A bigger case is usually better at cooling, a 9-10 fan case will not be noisy if tuned and built properly.

★★★★★GOOD, QUIET, COOL. [Literally]
BETTER THAN EXPECTED. Replaced the stock "rgb fans" that were installed previous. WAY BETTER. QUIET. POWERFUL. DEFINITELY saw a decrease in temperature using "SPECY" pretty darn satisfied so far. Used for a few months so far.

★★★★★Great 140mm fans if you are going for silence.
Fantastic fans for the price, used for a build in the Be quiet pure base 900 case, and they move a lot of air, have a great range for fan speed, and are quiet as always.
