Corsair fans with PWM?

[Mychon CZ]

Hi, I have two questions.

Has Corsair AF120 Performance Edition and AF140 LED Quiet Edition PWM? If not, can I change RPM in Bios or somewhere?

Thank you for answers.

Hi, well yes both should come with 4-pin PWM connectors. I have these fans myself and they are pretty neat!

Check if they have PWM connectors on the site you're buying them from. Corsair may have editions without PWM but i don't really know. I doubt they do, but juct check to be sure.

You can control your fans by changing voltage. You can chose between 5V, 7V and 12V. You can change this in the BIOS or use a Fan controller. You could possibly have one in your case (i do). I don't know if there is software that allows you to change the fans voltage but i bet there is.

Update: I looked it up! You can use a program called SpeedFan, but i would recommend hardware, not software to change the speed of your fans.

They are not PWM controlled fans. They are voltage controlled.

If the motherboard allows the changing of voltage level to the fan headers then should be able to control fan speed that way.

That's weird. Mine are PWM controlled...

From back in October:

Both models only come in 3-pin versions, and there was no word on whether any PWM versions would be released.

I still don't see any PWM versions on Corsair's website.

Oops, I already choose 'Best solution' and then I see, that there are another answers. So I only can hope, there will be 4-pin. But 25 or 30 dBa is not very much...I hope. Thank you guys.
