hi guys,
i have this problem with the AMD HD7950 DDR5 3Go fans, the 2nd fan (near the HDD) starts spinning only at 80°C (tested on MSI Kombustor Stress test)
i need some clear ideas about this problem, thank you
Depends on the exact make/model card, some may switch to additional fan/s at certain temps.
Using 3rd party oc/fan control apps together with wattman/overdrive can sometimes conflict.
