hello guys
i have an issue with my armoury crate which is i always use manual mode when gaming and i always use the thermal target to
75C as you can see in this pic:

the lowest degree that avilable so i dont want my gpu heat to get
86C or higher when gaming for 4 hrs or more so sometimes it works and the degree dosent go above 75C and sometimes it doesn't even if i apply the setting more than once
anyone know the issue for this problem?
thnx.
