I have got 650 watt power supply unit. It has a lot of SATA cables. There is two cables, both splits to 4 molex connectors. Two molexes are used for my two optical drives. 3rd one is used for ATI Radeon HD 4650 (AGP) and there is an 80 mm case fan attached to that molex. So that calbe leaves one molex free.

My question: is it safe to add 40 mm fan to that molex?

Both fans are from Xilence.

This cannot be answered properly without information about your power supply and its current load on the rail.

A fan is usually 5 watts.

So take your PSU info, see maximum load on the rail, calculate your current usage and if you have more than 10 watts to spare it should be OK.
