be quiet! Pure Wings 2 140mm PWM fan

  • 140mm
  • <1600 RPM 60-65 CFM (I think this is the 1000rpm model)
  • Rifle
  • 15-20 dBA
Edit: These fans don't have rubber grommets/mounts.

Edit 2: Not sure which model these fans are. They see to have specs from both their regular and high speed on newegg. I'm thinking these are the normal speed quiet fans from the newegg overview and the part number in the specs. The 1600rpm seems to be a mistake on newegg.

Under the specs, Newegg lists the model as BL040, so it's max rpm is 1000 rpm (and not 1600 rpm the high speed version goes up to).

That said, these are great fans for $8. I own some of these and they are really quiet.

They should pair nicely in my fractal design define R5 which only has 3 of their GP-14 140mm fans installed.

I used these in multiple machines and they're dead silent and move air quite well. When you buy them in the 5-packs they come out to ~$9 and sometimes on sale for less.
