Too many fans?

Hi
I want to connect another case fan to my PC, but the 3 pin motherboard
socket is already used up by my VGA cooler controller. What shall I
do?

Thanks to anyone who helped me in my other thread (overheating).
I now have a lovely cool and quiet Zalman copper VGA cooler, which has
solved the problem. (Thank you to Paul for your recommendation.)

Fans also come with a regular Molex connector, you could use one of those.
If it is too noisy, there's a modification that can be done to change the
voltage to the fan.

This adapter connects the fan to a Molex disk drive connector. Since
there is a male and a female 1x4 Molex, you can cascade these. For
example, if you connected four of these in a row, then connected
one end to the computer, you could power four fans.

As one reviewer noted, the male 1x3 mini fan header is dangerous.
You should fit the fan with the power off and make sure the 3 pin
female on the fan, is securely fastened to the 3 pin male. If they
ever come apart, the pin with +12V on it can brush against the
computer case, which is at ground potential. That would throw sparks
and short your power supply. So make sure the 3 pin part is covered,
before turning on the power.

This is what the adapter is supposed to do:

Molex +12V -------------------- To fan's +12V
GND -------------------- To fan's GND
GND ---X (Fan RPM signal is not connected)
+5 ---X
