Arvind,
In a 10A dual PS, the fan was always On and the sound drove me nuts. I salvaged a thermal cut off from an old Yaesu battery pack and wired a relay to invert the action. The cut off opens at about 46C. Now the PS fan comes on only when on high load.
Cheers and Happy Deepavali to all celebrating.
