I bought a HD 3650 AGP videocard and the fan doesn't want spinning. Power connection is 4-pin molex and power supply is Gigabyte Superb 460W. I have linux operating system and this catalyst is not showing fan speed or temperature unfortunately. By the way, the card is working, I can watching HD videos through vaaapi, but I don't want gaming and no need extreme 3D, only HD capability. Is there any chance to turn on the fan? Can I try connect to power the fan directly? How dangerous using this card without fan?
