Hello,

I just installed Arch on my new laptop (month old). This system has a quad core AMD N950. Great computer!

Now on with the issue. I got my system all up and running nicely as I would like. I was using Windows 7 on this machine and CPU temps would average between 39-42 idle or doing very little stuff. I do have scaling working on Arch.

My CPU in Arch is idling at 48. I know from many years of using computers that heat is the enemy. Am I hurting my CPU by using Linux? A 9 degree difference between Winows and Arch is nothing to over look.

I am almost sure it comes from the fact that the CPU is not being under volted just under clocked. I looked at some under volting programs and it looks like they only work up to the K-8.

Thanks in advance!

I have no problems with my Phenom II, so I doubt that this is a undervolting issue, also because I can see the voltages change. Are you sure that your frequency-scaling is working correctly?

I have conky running and it shows it at 800MHz right now as well does cat /proc/cpuinfo.

I have also not messed with the ondemand thresholds, they are set to 95. Just a few minutes I started watching a video in flash and the temp shot up to 60 in no time flat with the fan screaming.

In Windows when it would hit around 58 or so it would undervolt and clock down a bit and would run nice and cool. I have never seen this machine go over 62 in Windows and that was gaming, if I wouldn't of stopped that movie I think it would of just kept climbing.

Where do I check voltage BTW?

Nevermind... No voltage sensor.. nice

Actually, after taking a closer look...

sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1: +47.4°C (high = +70.0°C, crit = +115.5°C)

acpitz-virtual-0
Adapter: Virtual device
temp1: +47.0°C

I'm not really sure either of those temps are CPU?

Maybe? In Windows it does read each core though.....?

Same problem here, only one temp for my CPU, so I would assume that this is your CPU, especially when I look at the high and critical temps.

By the way, other as in Windows Flash is really a hog on CPU-load in Linux, on my laptop (dual core AMD) i often get temps of 70-75°C watchin Flash. But 60 on your CPU is not that high and is not dangerous to your CPU.

I would assume that there is a special software running under Windows, that causes this behavior.

Thanks for the help.

I have actually been reading where lm-sensors has issues with some chips and I think I have one.

Here is just a small portion about borked sensors not reporting correct values.

The good temp reading in Windows could very well just be some kind of proprietary crap.

So I could indeed be running at 39 idle and could have shot to 50 when I paniced (that would be a fast jump but expected).

So I guess the moral of the story is, unless I suffer 3rd degree burns on the palms or a flame shoots out the side, I'm not gonna worry bout it....lol
