Lord_MessiCooler is utterly useless, as you can see after you attach the cooler , theres a space between cooler and device and as we know do remove the heat , physical contact is needed
Try to play with cooler and see if this problem still happen
If it's not happen after use cooler then overheat is your problem
Danishbluntdo you have any guide that you could point me out to?
Then its a thermal issue. Either fix it urself or get a 3rd party to fix it.
