Best Fan Upgrades

The Hl14 comes with 6x COOLERGUYS 120X120X25MM 3 PIN FAN MEDIUM.


  • 1700RPM
  • 32.5dBA
  • 73CFM
  • 2.47mm H2O

If you compare the specs of Noctua’s 120mm 3-pin 12V fans, the NF-F12 industrialPPC-2000 comes closest to the CG fan specs.

NF-F12 industrialPPC-2000

  • 2000RPM
  • 29.7dBA
  • 121.8 m3/h (72CFM)
  • 3.94mm H2O

The NF-A12x25FLX is comes close, but it has lower CFM and static pressure.


  • 2000RPM
  • 22.6dBA
  • 102.1 m3/h (60CFM)
  • 2.34mm H2O

So … I’d argue the iPPC-2000 is the best replacement. I run 3x 140mm iPPC-3000s in another build and they’ve been rock solid, no issues.
