A week ago EVGA started offering free thermal pads to users of its GeForce GTX 1070 FTW and GTX 1080 FTW video cards because of VRM overheating issues in some extreme usage cases (such as FurMark).
Today there's a post at TechPowerUp that EVGA has issued new BIOS versions for not only its GeForce GTX 1070 FTW and GeForce GTX 1080 FTW, but also the GTX 1060 FTW versions. This update adjusts the fan speed curve to ensure sufficient cooling across all operating temperatures:
"Recently, it was reported from several sources, that the EVGA GeForce GTX 1080 FTW PWM and memory temperature is running warmer than expected during Furmark (an extreme stress utility). EVGA has investigated these reports and after extensive testing, below are our findings:
On ACX 3.0, EVGA focused on GPU temperature and the lowest acoustic levels possible. Running Furmark, the GPU is around 70C +/- and the fan speed is running approximately 30% duty cycle or lower.
However, during recent testing, the thermal temperature of the PWM and memory, in extreme circumstances, was marginally within spec and needed to be addressed.
Users who don't want to do the VBIOS update themselves can request a warranty cross-shipment. EVGA also notes that all cards shipped after November 1 feature the new VBIOS.
