|Platform||Asus Z97I-Plus||OS||Windows 7||OS Version||64Bit|
|Product Version||4.50 beta|
|Fixed in Version||4.51 beta|
|Summary||0002584: Speedfan 4.50b2 forgets advanced option of NCT6791D during suspend-resume|
|Description||Speedfan 4.50b2 ist set to control the fans ("Advanced" -> NCT6791D -> PWM1 to PWM3 mode set to Manual (checked "remember it). "Fan Control" used to determine own profiles.|
Everything works well after cold boot. After a suspend-resume cycle the Asus UEFI fan control seems to take over. Checking "Advanced" -> NCT6791D tells for all "PWMx modes" tell me "DO NOT USE". Changing back to "Manual" does not work. A reboot fixes the situtation.
Feel free to contact me for further information or debug files. I appreciate your outstanding work. For me Speedfan support is vital before I buy new mainboards.
|Steps To Reproduce||Set "Advanced" -> NCT6791D -> PWM x mode to "Manual" (remember it)|
Make own profiles in "Fan Control" --> Works well
Goto to suspend mode
Wake computer --> Fan control via Speedfan is broken, Asus fan control kicked in
Check "Advanced" -> NCT6791D --> PWM x mode is set to "DO NOT USE"

I think the BIOS, or some other tool, is aggressively resetting those registers. SpeedFan reapplies advanced settings after resume. Now I need to understand what is applying a further change after SpeedFan.
Can you send me a SEND REPORT from SpeedFan's INFO tab after a resume from suspend? Thank you.
Report sent. I am with you with your assumption that the registers seems to be overwritten by -most certainly- bios. Bios fan control is in charge after resume - fans react to higher workload but speedfan control is not working. Manual exiting of speedfan and restarting speedfan leads to again working fan control by speedfan.
I try to monitor bugtracking frequently to assist in short time.
just add the speed fun reinitialization option on pc wake up/resume in the next build. and it would be cool to add custom fan profiles to an app!:)
for now I added a task that restarts the speed fan on wake up and it solved the problem...
