Ubuntu :: Display Info On CPU Temp & Other Sensor Information?

Is there a Linux application which can display motherboard and CPU sensor information and which also satisfies one other, absolutely key, requirement: It should be directly usable, after installation, by a reasonably intelligent computer application user. That is, it does NOT require deep internal knowledge of specific hardware or obscure system software customisation. It does not require hours, days or weeks of reading of documentation which is so crafted as to be the antithesis of end-user guides. It must be capable of being invoked easily.

This eliminates all software that the Ubuntu Software Centre lists when performing a search with the term 'sensors', with the exception of xsensors. All other software listed with this search installs without error but is then totally invisible to me - not even listed under 'installed software'. I am aware a key requirement to be a Linux developer is an advanced commitment to play games of 'I bet I can make my software harder to use than yours', but I'm too old for that now. I don't have a need to prove how technically capable I am.

Xsensors installs and tells me where it can be found, but is inadequate as it lists only 2 CPU core temperature readings. It does not give me any indication of motherboard temperature or fan speeds. That's all I want to do - get a simple snapshot of sensor values without having to resort to entering BIOS setup. It's the sort of information that is so easily available using the ASUS-supplied 'asus-probe' software under Windows. Is it possible, given the key requirement previously mentioned?
