Synapse auto fan changes itself to manual fan mode after windows restart | Razer Insider

Synapse auto fan changes itself to manual fan mode after windows restart


If i restart the Pro 17, the fan profile in balanced mode sets itselft to manual fan every time!

I am troubleshooting this for 2h now. Resettet the machines profile, reinstalled synapse (clean) etc.

if i shut down the Pro 17, Synapse keeps the auto fan mode. Only when restarting windows (20H2), fan profile changes itself to manuel and therfore the Pro 17 is loud, even when idling....

May be this is a bug or something?

Am I the only one with this problem ?
(Razer Blade Pro 17 Early 2021, QHD/3070)

Even did a clean Windows install, same problem. Every time I restart Windows 10, the fan profile in Synapse changes itself from auto (silent when idle) to manual....

This shit drives me crazy.

Considering uninstalling Synapse, since i dont want to change the fan profile every time I do a restart...
Synapse Autostart deactivated -> System keeps silent after restart
waiting 2-3 minutes then starting Synapse manual -> same problem, Synapse changes from last saved fan profile "auto" to manual an therefore fans are scraeming at me....

Hello, I can confirm this issue also on the latest Razer Blade Advanced 2021 QHD. Many people seeing the same type of behaviour in the previous models: https://www.reddit.com/r/razer/comments/lpkq0u/razer_blade_15_fan_speed_changed_to_manual_after/
Could you please check and fix this issue in Synapse, it is ongoing for years now.
