SSD temperature reading
#1
Hello. I've noticed that my M.2 SSD temperature reading does not change from 45 Celsius when the power plan is in balanced mode. When switching the power plan to Maximum Performance the temperature monitor starts to work.

Here is my log:

You can see the immediate change from 45 to 25 celsius when switching to maximum performance and back to 45 when returning to balanced mode. I prefer to use my PC in balanced mode but don't like that I can't see the temp of my m.2.

Thanks

Well, this is a really strange issue I have never seen before. I don't understand how could the power plan have influence on this.
Can you please attach the HWiNFO Debug File while in balanced mode?

Yes.

I downloaded the Western Digital SSD Dashboard, it shows the temperature and the same thing happens by switching power plans, so I don´t think this is a bug in HWiNFO.

That looks like some features of the drive (including temperature monitoring) are suspended in Balanced mode.
Must be some drive-specific 'feature'...
