I think they should spinn all the time at the given fixed speed 80% with -tt -80 right?
Anyone else with same issue?
here is my bat
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

Your fans probably stops spinning because gpu temperature drops below 50°C and they won't turn on until gpu temperature reaches above 50°C.
Most of modern GPU's have that feature.
