You need a splitter if it's a 4-pin fan. Even if it's NOT four-pin, you can buy an adapter to make it four pin.
Alright, I just got an old Compaq Deskpro from my aunt. I installed Xubuntu on it. Today, I opened it up, and saw that in the front of the case, there was a place for another fan. So, I decided that I would buy another fan for it. However, I've been looking, and there is no other place for a fanto be hooked up. How can I do this?
