RTX Titan got overheated easily

Hello folks,

I have an RTX Titan, which got overheated very easily, As long as I deploy any program on it, even if it is a very light one, the card reaches its thermal limit quickly and the process starts slowing down. The slowing down makes sense of course.

I have checked, the fans are spinning normally, so my guess is that the thermal paste or other stuff is malfunctioning. I am contacting customer service and they ask me to post my issue here first. Any thoughts?
