Question Why did my case fan stopped working?

[Vincentinus]

I have a Zalman I3 series case. The last 2 months everything was fine, but suddenly the leds and fans stopped working. Is there a way to solve this? Thank you in advance.

System working? just the case fan and led?

Everything fine. This case has an own fan controll part. So the fans are not connected to the motherboard. I am afraid the case control system died. Extra usb and start and restart buttons are okay. Thanksfully i still have warranty but i would be happy if i could solve it without sending back and wait for a month to get it back...
Edit1.: sadly i dont even have more than 1 free fan slot to put them on the motherboard...
Edit2. : omg i am stupid. One of the power supply cable loose a little bit.. I just put to together again an now everything fine... Im sorry for wasting your time and thank you.
