Question Corsair Sp120 Pwm?

[EmptyAlpaca]

Hi I bought the Corsair 220t which comes with 3 Sp120 RGB Pro fans that are meant to be pwm. But I noticed that the fans are 3 pin not 4 so are they really pwm or is it handled by the rgb control wire which s connected to a lighting node core?

According to fan specification on Corsair site SP120 RGB PRO is not a PWM fan.

Oh yeah sorry I saw on their website that the fan speed was up to 1,400 rpm and I thought that meant they where pwm, sorry
