If you place your hand on the power supply and feel no heat, then I'd expect the fan to be off.
I some a good size power resistors mounted to a heat sink with a fan that I used for testing power supplies. Testing with no dummy load is not very meaningful. The load is set up so it can be quickly rewired with resistors in series or parallel in different ways using a terminal block.
