The title of the question says it all really. I have a new laptop with Ubuntu 14.04 installed. There appears to be an overheating problem which fortunately does not appear to be affecting performance. I suspect it is my nvidia geforce card, even though I have Bumblebee installed.
In essence what I am looking for is a way, either via terminal or an app, to monitor the temperature of components so as to definably find out what may be overheating.
