MSI Afterburner Fan Speed 100%

NeverWinter · 21 Oct 2019 at 12:47

I have a GTX 1080 cooled by a Kraken G12 with an Arctic F9 PWM (connected to the card fan header) fan blowing on the card.

When booting up Afterburner sets the fan to 100% even though it is set to 40% and I have to move the slider to 100% then back down to 40%.

Any ideas why it's doing this?

Afterburner v4.61

Not yet, might give it a go later.

This is a fixed speed profile, not sure how a fan curve reacts.
AB is set to apply on start-up.
Profiles are set to short cuts.
I do press apply after moving the slider or what I have started doing was applying a second profile which is the same settings except a fan [rofile of 100% then re-apply the 40% one.

Didn't get a chance to try un-installing/downgrading yesterday.

Of course, that's why re-applying the profile works.

Adding some screenshots here to illustrate the issue.

This is at boot up, you can see Afterburner is setting the PWM to 40% but the fan stays at max RPM:

This is after applying a 100% fan profile and switching back to the 40% profile:

I've uninstalled and re-installed AB. Any thoughts?
