BIIIRLL Posted April 18, 2019 Share Posted April 18, 2019 (edited) Hi Everyone. Something happened today with my Corsair 780T case. all was just fine, when suddely the LEDs from my front case fans started to blinking. I opened the front protection and realized that all my case fans stopped (2 front and 1 rear). When I plug the fans cables directy in MOBO, they works fine. What can that be? I gonna put a pic that shows a fan working fine, plugged in MOBO and the other stopped above , plugged directly in case cables. https://ibb.co/dbRCsqR Edited April 18, 2019 by BIIIRLL The image doesn't appear Link to comment Share on other sites More sharing options...
c-attack Posted April 18, 2019 Share Posted April 18, 2019 Check the power/SATA cable that supplies the 780’s front fan controller. Look for any breaks in the wire or loose connections. Link to comment Share on other sites More sharing options...
BIIIRLL Posted April 20, 2019 Author Share Posted April 20, 2019 hey.. I tried it. Unplugged and plugged it again... nothing changed. I don't found any problem in the wire. Broken places, anything. Don't have any idea. Link to comment Share on other sites More sharing options...
c-attack Posted April 20, 2019 Share Posted April 20, 2019 It suggests there is a problem with the case's built in fan controller. Blinking LED fan lights and stopped fans seems like a power delivery issue. If there is no obvious breaks or loose connections, you can try a different SATA power connector from your PSU or temporarily attach it to a known working connector from a drive. There is also nothing wrong with using the motherboard to power the three fans individually. Some people like a manual fan control. Some people prefer programmed behavior.
