"220V Cooling Fan" at the bottom of the heatsink temperature probe close to embed a core position, the probe is connected to the intelligent temperature control circuit, a temperature control circuit automatically adjusts "220V Cooling Fan" speeds depending on the graphics card temperature measured, Work has been reached so that the graphics always aim at an ideal temperature. Display chip heat small, low core temperature corresponding fan speed is relatively low, "220V Cooling Fan" noise will be low. Temperature probes will detect the results transmitted to the smart temperature control circuit, intelligent temperature control circuit will automatically adjust the fan speed, speed up heat dissipation, so that the card can still run at a suitable temperature, the stability of this system has been secured .
