getting case fans to work

[bolejniczak]

Case has 3 fans but motherboard has only one fan connector. What is the best way to hook up the other 2 fans? Maybe using an adapter from the power supply?

Yes..most likely you have molex connecters to spare.
In that case you may want this.
Be aware that you'd have no control of speed

you have a few options.
first, if the fan has a molex connector as well as the 3 pin connector, then use the molex connector to connect the fan to the psu, or, like dudio said, is to get a 3 pin to molex adapter like this:

however, the fans would then start spinning at their maximum speed, which may be quite noisy depending on the fan model.

secondly, you could get a fan controller, which looks like this:

this way, you could individually control the speed of each fan that is connected to it.

finally, as far as i know, you could also get a fan hub like this:

this way, the fans would increase and decrease their speed together, so no individual control, but it is a lot cheaper and does not require a 5.25" drive bay
