Greetings Please be careful about assuming "Maximum" has anythinmg to do with what the manufacturer considers "The Danger Zone". It is quite often that "Maximum" fits in default or user set fan speed control watchdogs. I don't know of any CPU that will just roll over and die at any temperature below the human threshold of pain which is ~140 Fahrenheit. Most will operate considerably higher for fairly long times.

That said it isn't wise to run them at such temps because errors are more likely and lifespan is reduced. Laptops almost always run hotter than desktops but it is best to maintain them both but especially laptops to keep them optimally cool. Refreshing the thermal paste is a common requirement and most! especially! if! you! discover! it is one of those stupid double-sided tape foam monstrosities that only make assembly cheaper and easier. Check the paste, check the alignment, check the tightness of the fit and check to fan for any obstacles and proper lubrication. There are videos on youtube that can walk you through and you might even be lucky enough to see your specific model.

Yeah, I've dragged my feet on temporarily disabling my laptop by opening it up (my only spare won't take its hard drive, even in an enclosure), but I'd better soon. Clearly, applying some new thermal paste would be a good idea, and I can't assume anyone ever did it for this old laptop before I bought it last year.

And is my old tube of thermal paste probably still perfectly good after 6-8 years? It's just been sitting in a plastic bag in a closed box in my closet.

you may NOT be able to replace the CPU in a lap top most of the time they are soldered to the MoBo
unless your stupid rich and can shell out $1500.00 for the rig that can solder an IC package to a circuit board

ThinkPad T420 CPU-Upgrade auf Core i7 Quad-Core

it's them thin ones you need to worry about, they are "glued" to the MOBO. you have to replace a perfectly good motherboard even if you want to upgrade the CPU. Let lone replace it because "you" burned it up.

though with them one too can still replace the thermal glue/compound.

Intel Core i7-2760QM Mobile Processor 2.40 GHz 6MB PGA988 Quad-Cores SR02W

if you are going to replace it you might as well get a fast one for 50 US bucks.
