GPU Temp on VPCZ1

Hey guys, I would like to know what temp do u guys get when idling with your VPCZ1, when I am plugged in and the GPU speed is set to SPEED(AUTO), I get temperatures around 165-170F, or 73-76C, is that normal?
I am really starting to get worried!

 

Idling's around 60C. Playing in Silent mode I hit 79C max. Playing in Performance mode it's about 85C max.

Last week's pretty hot, the ambient temperature where I am got to 104. I looked at my GPU temps and it was about 65-ish. I thought: wow, my Z's so awesome, its operating temperature is below that of its environment!

Of course, I figured out what was wrong. Good thing I didn't post this on any forum otherwise I would have made a fool of myself.

Oh wait...

 

What is the ambient temperature? That does seem a little warm for idle. But I would worry more about what your temperature does under load. Idling at 73-76 isn't going to cause any problems for the GPU. That's not hot. But if you're seeing temperatures then in the mid 90s under load, I would start to worry. If you aren't breaking the 90 mark, then I wouldn't fret.

 

My Z idles around 48C

 

If you are plugged into external monitor GPU will idle quite a bit higher due to running at higher clock speed.

 

Yeah man, maybe that's my problem, I am always connected to a 32'' 1080p LCD, but do u think the laptop should idle at 75-78C? I'm not really a laptop guy, I'm more of a full case person, and I know laptop hardware is built to live with higher temperatures, but I am just feeling that almost 80 Celsius is kinda hot..
But thanks anyways

 

that seems hot still. Have you checked to make sure you don't have any processes maxing out cpu? Also, is the unit in a well ventiliated area and on a hard service? Lastly, check your thermal strategy in vaio control center and be sure to set it to balanced or high performance.

 

The power setup was at high performance, graphics at full speed, nothing messing with my CPU, just the external monitor.
However, now that I unplugged the notebook from the external monitor, my idle temperature is at 60-65Celsius, seems normal to me, right?

 

My GPU is idling at about 49-50 currently. Again, what are your ambient temps? My basement is quite cool. I wouldn't be too worried about 60-65. How hot does it get under load?

 

Idle doesnt' mean anything,
Load is what is important, check your load temps.
Mine idles @ 60 for what its worth. With overclock I get 86-89 under load.

 

But what is the thermal strategy set to? If it is set to silent things will get hot.

 

With my Z1, I find I get ambient temperatures of 50-62C for the gpu, and about 42-50C for the cpu.

Under (gaming) load, I find my cpu temps get to high 80's, even sometimes hitting 90C. The gpu tends to max out at around 86C. These temps are achieved with a laptop cooler; without one, the gpu tends to get to 90C too.

What confused me initially was that stress testing the gpu (e.g. furmark) only got the gpu to about 80C, so in fact I see higher temps in gaming than I do in stress tests that only stress the gpu.

I think it boils down to the temperature management for the cpu; my i540 likes to run hot it seems, and I'm not sure if this is just an outlier or if its designed to run that way. I suspect that the new i processors may actually be set up to run very hot; on a different thread on nbr (relating to dell) I recall someone mentioned that t-junction for an i430 is 105C, i.e. the cpu doesn't even start to throttle until you've hit that temperature. Failure would come even higher than this temp.

I'm much less concerned about temps now than I was a couple of weeks ago when I first noticed the temp levels; under full load, even whilst gaming for hours, the temps stay in the mid-80s. They drop very rapidly once I stop gaming. Whilst gaming, despite the high temps, I see no evidence of throttling or frame rate drops.

I think in the z, the gpu temp you see is driven as much by cpu load (and consequent cpu temp) as it is by graphical load. Highish ambient temps may be partly due to background processes that you're running.

 

Is this actually correct? I thought that under the silent profile, the Z reduces the temperature it allows the cpu and gpu to achieve, i.e. silent profiles lower performance rather than increase temperatures under load.

I find on my z that running on the performance profile, I see higher temps than if I run on the balanced or silent profiles, i.e. thermal management is set up to maximise cpu and gpu performance at the cost of heat and therefore fan noise.

 

^Yes. If you set to silent, it will do everything possible to not spin the fans up to high. It will throttle, etc. But in my accidental experience I notice things will get toastier unnder normal use

 

I have the same experience as you: under performance, the CPU isn't throttled and the temperature is higher than under silent mode. My app is Oblivion, and I've observed this many times.

 

I'm talking about normal (low cpu/gpu) use.

What I've found is that if you leave the performance profile on high performance but leave the thermal profile on silent during light use temps will be higher...during heavy use temps will be lower (lower than when the thermal strategy is set to performance) due to the miserable throttling.

Just my experience.
