My fans are not working
Our recommendation is that you check whether is a loose connection. You can check if the power connection is properly connected - sometimes it can be loosened by moving or similar and can cause a loose connection.
In addition, it can also be beneficial to see if your fans are connected to the motherboard.
If the above does not have an effect or you need help checking for a loose connection, then feel free to contact our support department and we will be happy to help further.
