Fan for hard drive

[Magnum]

I would like to attach a fan to the connector shown show in this pic.

It has 2 voltages, 5.0 and 7.0.

Which value should I use to look for a fan?

Thanks.

The 4-pin molex connector used for drives supplies 5v and 12v. If you mean a molex to 3-pin fan header, like this, they should be readily available.

I wan't to use 2 of the pins of the 4-pin connector to power a fan that I will use to blow on my hard drives.

Case fans commonly have a molex connector, and there should be specialized drive fans available.

I found this.

I will have to find out if I can switch out my CD and DVD player for the 2 hard drives in order to be able to mount it.
My system is an Optiplex Gx110.
