Always on fan speed slower than PWM fans
-
I used to use thermo control on my cold section fans, but I switched them to the always-on headers. When they were PWM controlled they were SCREAMING, and now they barely even bother me. Is that normal?
-
@gnydick It sounds suspiciously odd (excuse the pun). Might it be that you have a jumper set incorrectly such that Vfan is incorrect for the fans you are using? Eg, 12V being supplied to 24V fans?
-
Could the screaming sound have been the PWM frequency, when you were running the fan at less than 100%?

@dc42 sorry, screaming was used as a colloquialism to mean REALLY fast.

@deckingman it's always a possibility, I haven't touched that jumper, I'll take a look tomorrow.
