Question Fans plugged into Commander Mini run at max speed when PC wakes from sleep

Hi guys,

So I have a minor issue and was curious if anyone else has experienced this issue and knows how to remedy it.

I'm using a Commander Mini with 5 fans plugged into it (2x AF140 on front of case, 2x AF140 on H115i radiator, and 1x AF120 on rear of case). Every time I wake my PC from sleep, all five fans are at max speed, regardless of the profile set before it was put to sleep, and will stay at this speed. Every time I wake my PC, I need to go into Link and re-select my low-speed fan profile, though it still shows it's selected for the fans to re-enter a low-speed state.

To add, this happened to me on Windows 7 too (now on 10) and on my old AMD build (now running Intel) so it seems like it's definitely a Commander Mini bug. Only thing I can think of is some sort of incompatibility between the 3-pin AF fans and the Commander? Maybe the service crashes on wake and doesn't restart until I select a profile?

Currently on Link 4.7.

Any help is appreciated.

Thanks.

If I remember correctly this is a known issue with Commander Mini having trouble waking up from sleep and unfortunately won't be fixed. :(

Nope, I have the same problem using the Commander Pro. My fan profiles do not work after waking from sleep and my H115i becomes unresponsive to any changes. Disabling and Enabling via device manager fixes the problem until the next sleep. It believe possible to create a script to automate this process, but I ended up just turning off sleep altogether. It is not worth the risk of overheating my hardware if I forget...

Thanks for the response, BangDead. Weird though, as my H115i is still responsive after wake, it's just my fans that are maxed out and need to be reset.

To clarify the fans still run after sleep but my profile does not load and I am unable to change the speed of the fans on the cooler.

Idea Try using Device Manager to disable and then enable the H115i

If you exit CL4 then from Windows Device Manager you disable and then enable the H115i, restart CL4 can you then change the fan speeds?

Yes, that is the only reasonable workaround that I have found. I just ended up turning off sleep altogether to save me the trouble.

Arrow I suspected it would

I suspected it would and I think the root cause is the SIUSBXP driver does not handle Windows PNP power transitions correctly.

In my code I worked around the issue by automatically doing the disable/enable when the system resumes from sleep, see http://forum.corsair.com/forums/showthread.php?p=857462

I am not sure what to suggest, you could try asking Corsair to fix their driver.

This is something I forwarded to our Validations team to look into. If it's driver-related, we may or may not be able to fix it depending on whose driver it is. But we can at least look into it.

Dustin,

I've had my commander mini for like 2 years now. I've always had this issue since day one. If this was a known issue with the commander mini, why was it never resolved?

Oops Corsair don't have the CLCC firmware source

It's partially down to Corsair not having the CLCC firmware source, but I can't see any good reason why CL4 can't work around the CLCC firmware issues as I managed to do this in my software.
