Hi there folks,

 

what i have here isnt so much a problem as it is a question. I have an Asus Aspire A515 51G 58ug. ( Thats an I5 8250u, with a Geforce MX150 8gb ram and a 256SSD. ) Everything is running fine, the temperatures measured with coretemp (39/40 C idle, 49-60 C on 2D, 65 - 83 on 3D games) are well within reason for a Multimedia Mass Market Laptop. Here is a question though:

 

Not all of my games can actually take advantage of the 4 cores of my CPU - Neverwinternights 2 for example does not. (And since it isnt programmed all that well, it still gives my CPU a run for its money, despite being 12 years old. NWN2 slathers all of its load onto one core, which consequently is more taxed and runs a bit hotter than the others.

 

My question for you guys is, if running a single core on a multicore CPU for extended periods can damage the CPU as a whole. ON lower temperatures, effects like these are probably negligible, but what about a long gaming session?

 

I could upload a Coretemp log of me playing NWN2 for an hour or so. Last time i checked, i never crossed 78 C even with the unlucky core NWN2 decided to agonize.

 

If you got the time, some advice would be appreciated,

 

Sincerely,

Disorganizer

I don't think using just one core can damage a cpu, but always keep an eye on temps just in case something goes wrong.

FWIW.

 

Systems are built to run programs...some programs utilize multicores, some don't.  Some multitask, some don't.

 

From checking when I am encoding video...I would say that it would be unusual for all cores to be involved in a single process/program.  Not all programs are written so that require or can take advantage of multiple cores of a system.
