A week ago I built my new pc. The case came with 2 in-built 3-pin case fans, and my motherboard only has one 3-pin SYS-FAN connection. One case fan is in top-rear of the case, and the other fan at the bottom-front.
Currently I'm using only the rear-top fan and I do not have problems with heat or airflow. However, I'd like to connect an additional fan, just because I have it.
There are two possibilities for the fan on the front:
- I can connect it directly to the PSU with a cable like this. The con is that the fan will always rotate at full speed. I do not know if fans are used to rotate at full speed.
- I can connect it with a Y-cable like this or this. Will a splitter like that work well? Looking at the second link, it seems that the speed-controlling cable is missing. Is this also the case in the first one?
I do not want to use a fan controller.
What do you recommend?
