CONNECT A 12 VOLT 2.6 WATT PC COOLING TO 220 VOLT AC AT 50 Hz?

could someone out here help me connect a 12 VOLT 2.6 WATT PC COOLING FAN to 220 VOLT AC 50 Hz. I thought of using a 15 VOLT 500mA transformer to step down voltage and using a 7812 at output of transformer to stabilize voltage...but how to regulate the current???...please don't advice using a resistor parallel to the fan...to be pin point ... HOW TO REGULATE CURRENT AT THE O/P OF 7812??? WHAT SHOULD BE THE I/P CAPACITANCE VALUE w.r.t THE 7812 CKT???


a circuit diagram would be appreciated..

Here's a suitable circuit.

The fan takes only the current it needs, the supply provides only what it needs, don't worry about it.

Also, depending on the usage scenario of the fan, you can cut noise substancially by undervolting these pc fans below about 80%. You don't see much higher rpm or airflow for that last 20% anyway, so consider a lower voltage (7-10vdc) adapter if that's also available -saves a part (regulator) and a lot of noise.
