MacBook Air fans go full speed when plugged


After a few months of use, my UD-CA1A makes my MacBook Air to turn its fans to full speed. I have reset PRAM and all that. I have also replaced to hdmi cables and removed all peripherals but the monitor.


Hello Lino, thanks for posting. I am sorry to hear this issue and I will be happy to help.

Thanks for letting us know the steps taken to troubleshoot already.

From here we’d want to see if a replacement dock exhibits the same behavior. Please contact us directly at with ‘Ticket Number 294098’ in the subject line so we can match everything up and facilitate this process directly.

Please also include the Amazon Order ID number for your purchase, the serial number from the bottom of the dock and your preferred shipping address in the body of this email to our support team.

We will then begin the replacement process and follow up with a direct email with tracking information.

Thank you,

David W.
