150

Lowest price ever for the non PST version: https://au.camelcamelcamel.com/product/B07HC7P3HJ

Comes down to $5.17 per fan which is utterly ridiculous considering how they perform. No wonder they get gobbled up in minutes.

Previous comments have mentioned that you can add anything from Amazon UK to make up the $49 then cancel it and still get free shipping.

  • Are these pwm?

    • No, these are the non-pst (non-pwm sharing technology). They'll just tick along at fixed speed, 1800rpm.

    • No, speed fixed at 1800rpm

    • So basically they’re always on… I suppose if they’re quiet enough anyway no issue. Depends on the life of the bearing perhaps though

      • around 7 years probably, and you can use speed limiters

        • Hmm if my memory is correct chassis fans are normally controller by voltage limiting by the motherboard - unlike cpu fans which are EXPECTED to be PWM.
          Therefore they’ll modulate just fine, but without PWM the current might be limited per fan?

  • Wow 5 fans that blows me away.

  • If I use these as case fans can I still control the speed in the bios??

    Or is it worth waiting for the PWM ones and replacing my Corsair SP120s on my AIO as well?

    • Nope, that's what the PWM would do. These are fixed speed.

    • You can still change fan speed using the DC fan option in BIOS… Pretty sure most, if not all boards will allow you to do it from the board headers. But not sure about if you connect it to the AIO though.

    • Yes, nearly all boards will automatically switch to DC voltage control when they detect a 3 pin fan plugged into a 4 pin header, so you can control them just fine. They will work on your AIO or air cooler by plugging them into any header that can be controlled based on CPU temperatures. I avoided NZXT CAM for years by using the UEFI to set the fan curve instead.

      The benefit of PWM is more granular RPM control and lower minimum RPMs, which can be useful for forcing quieter operation.

  • The P14 is never in stock when I look arrrrgg

  • Thought it was PWM, was about to order. Glad I double checked.
