Intel optane causing high CPU usage - c940-14"

2019-12-24, 23:01 PM

Anyone else seeing this? 

 

Today is the first day I've really tried to use the c940 at work, for work and I'm seeing/hearing intolerable CPU and fan thrashing going on.

 

This thing was stuck running at 90 degrees C while I was chatting with a coworker. I had chrome (4 tabs) VS code (idling) and nothing else runnign when I noticed the temperature.

 

Looking in the task manager showed this - 

 

It was occasionally going up to 30% or so, and 'System' alternated with 'Explorer' for the other part of the outrageous CPU usage.

 

Anyone else seeing this? 

 

My machine is fully updated...

This happened to me all of a sudden today too. Not sure what caused it, and it persists between reboots. I already have issues with my C940 fans running nonstop and this optane process just started kicking the fans up even higher :/

argh.

 

This machine drives me nuts. I really want to like it/keep it because of the build quality & feel but..

 

* fans are obnoxious

* charging sucks

* no multimedia keys

* (4K) screen has poor dynamic range/contrast

 

Intel Optane seems like complete garbage anyway (right now at least) and it's only getting dumped on us through manufacturers.

 

Really frustrating to know

Same bro, I feel you. Intel Optane begins using high CPU after I game. But as of late it's been resolved on my end.

For the complaints you mentioned, make sure you give a try at undervolting since that solved the fan issues for me quite consistent.

I just found that you can disable the optane feature.

So I'm giving that a try for the next couple days.
